Google Antigravity 2.0 Setup Guide: Clash Verge Rev Routing for CLI and Gemini API (2026)

1. Who this is for—and what Antigravity 2.0 changed at I/O

You already run Clash Verge Rev with a subscription or self-managed Mihomo profile, and you want reliable paths to Google’s newest agent developer stack without tunneling your entire laptop through a congested default route. At Google I/O 2026, Google repositioned Antigravity as an agent-first platform rather than a VS Code derivative: a standalone desktop application for orchestrating multiple agents in parallel, scheduled background tasks, and ecosystem ties to AI Studio, Android, and Firebase. The Antigravity CLI—invoked as agy—replaces the Node-based Gemini CLI for most consumer and Pro accounts, with a migration deadline of June 18, 2026. The Gemini API gained Managed Agents: a single API call spins up an agent that reasons, uses tools, and executes code in an isolated Linux environment, powered by the Antigravity harness on Gemini 3.5 Flash via the Interactions API. This article does not replace Google’s account eligibility or billing documentation; it explains how to engineer proxy routing so when Google says “available in select regions,” your Clash policy—not your ISP’s mood—decides which sockets qualify. We differentiate from consumer Gemini Spark guides on this site: those focus on the Gemini app and personal agents; here we target builders installing binaries, calling APIs, and running multi-agent harnesses from terminals and IDEs.

2. Why “toggle VPN” fails for Antigravity’s multi-process footprint

All-in-one VPN clients optimize for a single cooperative browser session. Google Antigravity 2.0 in 2026 spans at least five distinct traffic shapes: the standalone desktop app downloading updates and syncing agent state, the Go agy binary talking to model and tool endpoints, OAuth flows on accounts.google.com, programmatic calls to generativelanguage.googleapis.com for Managed Agents and SDK workflows, and browser sessions in aistudio.google.com when you prototype Interactions API payloads visually. The CLI install path itself is a network probe: curl -fsSL https://antigravity.google/cli/install.sh | sh must reach Google-hosted distribution endpoints before you ever run agy plugin import gemini. Go binaries often honor HTTPS_PROXY when exported, but desktop Electron shells may ignore shell profiles entirely unless system proxy or TUN captures them. Fake-ip DNS pools in Mihomo profiles can break Google sign-in if synthetic addresses disagree with what your browser cached five minutes ago. Clash Verge Rev matters because you can steer only the Google AI and Antigravity slice through a quality relay while keeping npm registries, internal Git, and video calls on predictable DIRECT paths—something binary VPN switches handle poorly once you live in both worlds daily.

3. Inventory surfaces: desktop app, CLI, SDK, Managed Agents, AI Studio

Before editing YAML, list which binaries and browsers actually talk to Google during a failing Antigravity session. The standalone desktop app typically loads UI assets from Google CDN hostnames and authenticates through standard Google OAuth—often the same accounts.google.com redirects you know from Workspace, but with additional Antigravity-specific endpoints under antigravity.google.com or related Google developer domains. The Antigravity CLI shares authentication and context with the desktop app per Google’s documentation, yet terminates TLS from a separate process that may not inherit IDE-integrated terminal env. The Antigravity SDK lets you define agent roles, tools, and sandbox constraints on your own infrastructure—or delegate execution to Managed Agents in the cloud. Managed Agents traffic hits the Gemini API and Interactions API backends; your scripts may also touch cloud.google.com documentation or Cloud Console if you wire enterprise billing. AI Studio remains the visual sandbox for prototyping agent configs before you POST them programmatically. Write this inventory in your team runbook with timestamps from Google I/O 2026 onward so future hires do not resurrect 2024 Gemini CLI hostname lists missing Antigravity-era redirects. Document which account tier you use (consumer Pro versus enterprise Workspace); Google has stated enterprise Gemini CLI support continues separately from the consumer migration to agy.

4. Build a hostname list from Verge Rev logs—not forum copypasta

Forums still circulate prehistoric DOMAIN-SUFFIX shopping lists; Google’s CDN and auth edges move faster than that—especially the week after a keynote. Reproduce a failure—install script stall, blank agent picker, Managed Agents timeout—with Clash Verge Rev logging verbose enough to print policy decisions. Record every Server Name Indication string, then group them: primary Antigravity and AI Studio hosts, OAuth redirects, static CDNs, CLI distribution endpoints, telemetry you may REJECT on purpose, and enterprise forwarders that must bypass Clash entirely. Minimum candidates to validate on your network today include antigravity.google.com, aistudio.google.com, ai.google.dev, generativelanguage.googleapis.com, www.googleapis.com, and accounts.google.com during login. If Managed Agents upload artifacts or pull dependencies inside Google’s isolated Linux sandboxes, your local machine still initiates the API call—watch for additional *.googleapis.com names in the same session trace. Keep package registries, internal APIs, and RFC1918 ranges on explicit DIRECT lines above any wide Google suffix you add later. When remote rule providers back your profile, refresh on a sane interval; hammering strangers’ lists every minute does not make Antigravity CLI respond faster.

5. YAML scaffolds for Antigravity 2.0-era Google traffic

Exact subscription files differ, but ordering does not: specific domains before coarse GEOIP buckets, corporate guards first, MATCH last. Below is illustrative—rename GOOGLE_AI to match your outbound group (auto, url-test, or a dedicated US/EU selector).

# Assume outbound group GOOGLE_AI exists (stable US/EU node recommended)
rules:
  - DOMAIN,antigravity.google.com,GOOGLE_AI
  - DOMAIN,aistudio.google.com,GOOGLE_AI
  - DOMAIN,ai.google.dev,GOOGLE_AI
  - DOMAIN,generativelanguage.googleapis.com,GOOGLE_AI
  - DOMAIN,accounts.google.com,GOOGLE_AI
  - DOMAIN-SUFFIX,googleapis.com,GOOGLE_AI
  - DOMAIN-SUFFIX,gstatic.com,GOOGLE_AI
  - DOMAIN-SUFFIX,googleusercontent.com,GOOGLE_AI
  - DOMAIN-SUFFIX,your-corp.internal,DIRECT
  - IP-CIDR,10.0.0.0/8,DIRECT,no-resolve
  - GEOIP,CN,DIRECT
  - MATCH,GOOGLE_AI

Swap hostnames for what your traces proved; duplicate stanzas if you rely on regional Google endpoints not shown here. Prefer scalpel DOMAIN lines when compliance teams fear over-broad suffixes; widen to DOMAIN-SUFFIX only after measurement, not before keynote excitement. If you run url-test groups, pick health-check URLs that correlate with sustained TLS to Google, not random ICMP-friendly CDNs unrelated to API latency. Annotate Git commits when you add lines after Google I/O 2026; six months later you should still know whether a rule was measured necessity or anxiety.

6. Process proxy and PROCESS-NAME rules for agy and the desktop app

Domain rules alone cannot help when a binary opens sockets without sending the SNI you expected—or when install scripts use raw IP literals briefly before TLS. On Windows and macOS, Mihomo supports PROCESS-NAME rules that map specific executables to a policy group. The Go agy binary may appear as agy.exe on Windows or agy on Unix; the Antigravity desktop app ships its own binary name per platform—verify with Task Manager or Activity Monitor rather than guessing. Example pattern (adjust names to your traces):

rules:
  - PROCESS-NAME,agy.exe,GOOGLE_AI
  - PROCESS-NAME,Antigravity.exe,GOOGLE_AI
  - PROCESS-NAME,agy,GOOGLE_AI
  # ... domain rules follow ...

Process rules sit early in the list but should complement—not replace—domain rules, because child helpers may spawn under different names. TUN mode captures everything when process inventories grow unwieldy; accept the broader routing footprint and maintain explicit DIRECT guards for banking, LAN, and corporate VPN traffic. On Linux, install scripts and package managers may run as root with different env; document whether sudo sessions inherit proxy variables or need TUN.

7. Policy groups: pick exits that survive long Managed Agents sessions

Antigravity demos emphasize parallel agents, but real sessions push sustained upload/download through the same relay node—especially when Managed Agents execute code and stream tool results back through the Interactions API. Create a dedicated policy group—call it GOOGLE_AI if you like—containing nodes in regions Google actually serves for your account tier. Avoid ultra-cheap relays that collapse when you attach large context payloads in AI Studio or run parallel agy subagents against Gemini 3.5 Flash. url-test is fine when health checks hit Google-adjacent TLS endpoints; pure latency pings to unrelated hosts lie constantly. Document fallback behavior: if every node in the group fails, do you want DIRECT (often worse for region locks) or hard failure (clearer for debugging)? Teams sharing one subscription should align on the group name in YAML comments so incident responders speak the same vocabulary during post-I/O migration spikes toward agy.

8. System proxy versus TUN for CLI, desktop, and SDK workflows

System proxy mode plus a working mixed-port keeps blast radius understandable: Chromium-based AI Studio tabs, Edge, and many shells align when HTTP_PROXY family variables point at localhost. That fails for the Antigravity desktop app if it ignores OS proxy, or for Go binaries started before you exported env. TUN mode captures those black sheep because the kernel routes packets, not because Google suddenly standardized developer etiquette. TUN is broader—sloppy exclusions may steer unrelated UDP gaming or banking apps through nodes you never audited. On Windows, plan for Hyper-V and WSL2: Linux namespaces do not mirror host env automatically; document a hybrid with explicit proxy IP toward the Windows listener when running agy inside WSL. On macOS, Little Snitch prompts still matter; laptop sleep sometimes detaches TUN adapters until you toggle Verge Rev off and on. Start conservative: system proxy for AI Studio in the browser, env vars for agy and SDK scripts, TUN only when logs prove stubborn DIRECT escapes from the desktop app.

9. Environment variables for agy, SDK clients, and Interactions API scripts

A practical trio is HTTPS_PROXY=http://127.0.0.1:<mixed-port>, mirrored HTTP_PROXY, and optionally ALL_PROXY=socks5://127.0.0.1:<socks-port> for tools demanding SOCKS semantics. Maintain NO_PROXY for localhost, 127.0.0.1, ::1, and internal suffixes so artifact uploads do not hairpin through another continent to reach a LAN registry. After edits, restart integrated terminals or IDEs; hot-patching shell profiles is useless if a long-lived agy daemon started before exports landed. Google client libraries for the Gemini API may honor application-default credentials and custom roots in enterprise MITM environments—Clash cannot fix counterfeit corporate CAs inside your runtime. When testing Managed Agents, run curl -v https://generativelanguage.googleapis.com/ from the same shell your automation uses; you want proof TLS completes, not necessarily HTTP 200 on every path without credentials. For the CLI install script itself, test curl -v https://antigravity.google/cli/install.sh through the mixed port before piping to sh—a common failure mode is the script never downloading, not agy misconfiguration.

10. Fixing CLI download failures and Gemini CLI migration friction

Search traffic spiked after I/O because developers simultaneously tried to install Antigravity CLI, migrate plugins with agy plugin import gemini, and retire the old gemini binary before the June 18 cutoff. Install failures often trace to blocked access to antigravity.google distribution hosts, not broken Go compilation on Google’s side. If curl reports connection reset or timeout, inspect Mihomo logs for DIRECT hits on Google domains during the install attempt. OAuth browser flows for agy auth require accounts.google.com and sometimes localhost callbacks—ensure fake-ip settings do not poison loopback handling. Skills migration from .gemini/skills/ to .agents/skills/ is a filesystem task, but verifying migrated agents with live API calls is where routing bites: each test invocation should map to your GOOGLE_AI group in logs. Enterprise Workspace accounts excluded from the consumer migration may still run legacy Gemini CLI indefinitely; do not apply consumer migration advice to those tenants without reading Google’s enterprise comms.

11. DNS, fake-ip, and OAuth loops after Antigravity launches

Mihomo stacks often enable fake-ip for speed; synthetic addresses confuse mDNS, split-horizon corporate DNS, or Google sign-in if layers disagree. Symptoms include endless accounts.google.com redirects, “Something went wrong” banners in AI Studio, or Managed Agents calls that load only after you disable Clash entirely. Mitigations include targeted real-ip behavior for auth hostnames, disciplined fallback resolvers, and flushing OS DNS caches when you change profiles during Google I/O 2026 week experiments. Captive portals and hotel Wi-Fi poison DNS too; validate with dig through a trusted upstream when failures appear only offsite. Huge ad-block hosts files occasionally blacklist shared Google CDNs; diff before blaming Managed Agents capacity. Keep GEOIP databases fresh; stale ASN data steers traffic through wrong cities until you refresh providers inside Verge Rev.

12. Operational checklist inside Clash Verge Rev

Confirm the intended profile is loaded—not yesterday’s experimental YAML left selected after keynote livestreams. Manually refresh subscriptions and wait for remote rule providers without TLS failures. Stress-test your GOOGLE_AI group with sustained downloads; skinny relays collapse under multi-agent uploads even when ICMP looks fine. Disable experimental toggles you cannot explain; nightly Mihomo builds fix rare HTTP/2 bugs and introduce routing surprises in the same tarball. Back up working configs before refactoring; symlinks without copies are how distributed teams lose reproducibility across time zones. If Verge Rev autostarts at login, guard against race conditions where agy or the Antigravity desktop app opens before listeners bind—a short delay is inelegant yet effective. Monitor RAM when gigantic rule sets meet verbose logging on laptops already running Docker, three browsers, and a desktop agent orchestrator.

13. Verify Antigravity and Gemini API access before long agent runs

From the browser profile you actually use, open aistudio.google.com with DevTools network filtering enabled; confirm TLS handshakes complete without certificate warnings. From your SDK shell, probe generativelanguage.googleapis.com with curl through the mixed port when isolating env inheritance doubts. Run agy with a minimal prompt or health subcommand and watch Mihomo logs map each domain to your intended relay—not accidental DIRECT. POST a lightweight Managed Agents or Interactions API payload and confirm streaming responses arrive without mid-session stalls. Compare two exit cities; when the second slashes time-to-first-token, your baseline node—not Gemini 3.5 Flash itself—was starving. Archive sanitized log snippets beside YAML commits so reviewers understand why a suffix rule exists post-Google Antigravity 2.0 launch.

14. Corporate VPN, Workspace SSO, and compliance boundaries

Always-on device tunnels and Clash TUN can fight for default routes; sketch who owns RFC1918 splits versus public Google API lists before enabling both. SSL inspection without updated trust stores breaks Google sign-in instantly—Clash cannot repair counterfeit corporate roots inside Chromium or Go TLS stacks. ZTNA agents rewriting global DNS need explicit coordination with Mihomo DNS panels, or you route half your lookups into contradictory universes. If policy forbids third-party relays for customer data or agent sandbox outputs, stop: elegant rules do not negate contractual obligations—even when Antigravity marketing is loud. Hybrid workers should test office Ethernet versus home NAT; asymmetric paths love to appear on only one side. Regulated teams invoking Managed Agents should confirm whether relaying API metadata through offshore exits violates data-residency commitments before enabling broad DOMAIN-SUFFIX,google.com rules.

15. Security notes when API keys ride inside TLS

Clash should not terminate Google TLS for routine development; you need ciphertext forwarding, not decrypted prompts in packet dumps. Guard AI Studio API keys, OAuth refresh tokens, and Antigravity auth artifacts; rotate when configs leak, and scrub Verge Rev logs before sharing—even redacted timestamps enable correlation. When exporting YAML for tickets, redact subscription tokens; airport links embed secrets more often than newcomers admit. Clarify jurisdiction: relaying regulated customer content through offshore exits may breach agreements even when the tunnel “works.” Require MFA on Google accounts that share emails with production cloud orgs to reduce lateral compromise after I/O-driven signup spikes. Managed Agents run in Google-hosted isolated Linux environments, but your local API calls still originate from your machine—treat local logs and env files as sensitive.

16. Troubleshooting when Antigravity still errors after routing fixes

First, confirm policy hits: live Mihomo logs must map failing hostnames to your relay group; DIRECT surprises mean ordering bugs. Second, rotate nodes inside the same group; universal failure points to DNS, MITM, or systemic blockage—not one bad city. Third, temporary global mode is a diagnostic scalpel, not a lifestyle; if stability returns, your split rules remain incomplete. Fourth, disable QUIC experimentally; some middleboxes mishandle UDP while TCP lives. Fifth, check laptop clocks; Google tokens fail mysteriously when NTP drifts. Sixth, distinguish Google account region messages from transport timeouts—only the latter belong in Clash tickets. Seventh, re-audit giant hosts merges for false positives blocking gstatic.com or install CDN names. Eighth, in WSL, ensure Linux namespaces reach the Windows mixed-port IP you think they do. Ninth, if install scripts fail, test raw curl to antigravity.google before reinstalling agy. Finally, open Google support only after attaching traceroutes and policy logs, not vibes alone.

17. Frequently asked questions

Why does the Antigravity CLI install script fail? Usually blocked or misrouted access to antigravity.google distribution hosts—fix domain rules and test curl through your mixed port.

Does the desktop app use the system proxy? Sometimes in Chromium surfaces, but validate agy and SDK subprocesses separately with env, logs, or TUN.

Why does AI Studio work while Managed Agents API calls fail? Different hostnames, DNS, and missing HTTPS_PROXY in the script shell dominate this pattern.

Should I use PROCESS-NAME rules for agy? Helpful on Windows when combined with domain rules; verify helper process names in live logs.

Still seeing errors after I/O? Split account eligibility from transport; inspect DIRECT slips, DNS, nodes, and OAuth redirects.

18. Why Clash Verge Rev beats opaque VPNs for post-I/O Antigravity workflows

Mass-market VPN apps optimize for streaming narratives and hide routing tables behind marketing globes; they rarely expose maintainable YAML, auditable domain rules for Gemini API and Antigravity endpoints, or Git-friendly diffs your platform team can review after every keynote. Hand-written firewall scripts rot when kernels update; maintaining parity across macOS, Windows, and Linux becomes a second job when you juggle a desktop agent app, a Go CLI, and cloud Managed Agents simultaneously. Clash Verge Rev with a Mihomo core lands in a pragmatic middle: tray toggles for daily use, textual policy for incident response, remote rule hydration for evolving SaaS footprints, optional PROCESS-NAME steering for agy, and TUN depth when browsers cooperate but SDKs do not. Commercial “AI accelerator” tunnels that refuse to disclose egress hops often fail security review for the same reason mystery relays fail procurement—whereas Verge Rev profiles stay yours to sanitize. The broader Clash ecosystem on this site already documents Gemini Spark, Claude Code, and Cline-style routing; aligning vocabulary means your team does not relearn contradictory networking lore every time Google ships an Antigravity headline.
