T3 Chat linking is live, but nobody knows it exists. You can't see how many tunnels you use. When you hit the cap of 3, you get a long relay error and a toast. The T3 Chat page is three clicks deep: avatar, Manage account, T3 Chat tab.

Now:

• Usage meter. "N of M tunnels in use" with one bar segment per tunnel. It shows in Settings > T3 Connect (desktop), the account T3 Connect page, and the T3 Chat page. It turns amber at the cap.
• Upsell at the cap. When the relay refuses a new tunnel for being at the cap, the Settings row and the Connect onboarding dialog show "You're out of tunnels (they cost us money)." with a nudge to Tailscale or T3 Chat. This replaces the raw error and toast. The button fits the plan:
  • Not linked: Link T3 Chat
  • Free or Pro: Upgrade on T3 Chat
  • Premier: Manage tunnels
• Direct link. Get more tunnels and Link T3 Chat open the account dialog straight on the T3 Chat tab. On the account T3 Connect page, Link T3 Chat starts the link flow in place.

The client works out the cap from the linked T3 Chat plan (3 / 10 / 100), because the relay does not expose per-user overrides. DEFAULT_MANAGED_TUNNEL_LIMIT moved into contracts so the relay and the client share it. Mobile is unchanged, because it can't add tunnels or link T3 Chat.

Proof: a new useCloudLinkController browser test turns a relay cap refusal into tunnelLimit with no error toast. vp run check:changed passes. Screenshots come from the real components in the browser test harness with fixture relay data. The dev setup has no Clerk or relay config, so I could not click through the live Clerk modal. That leaves __experimental_startPath: "/t3-chat" unchecked live, but it follows the existing /t3-connect path.

Walkthrough

The change adds a shared default tunnel limit and managed tunnel usage state. It handles tunnel-limit errors in cloud-link flows and adds usage meters, upgrade guidance, and account-link actions to profile, onboarding, and settings interfaces.

Changes: Managed tunnel usage and limit guidance

Layer / File(s)	Summary
Shared limit and usage state packages/contracts/src/relay.ts, infra/relay/src/environments/ManagedTunnelLimits.ts, infra/relay/src/environments/ManagedTunnelLimits.test.ts, apps/web/src/cloud/managedRelayState.ts	The relay contract exports the default limit, and relay limit handling imports it. Web state derives tunnel usage, plan limits, upgrade options, and refresh behavior.
Cloud-link tunnel-limit handling apps/web/src/cloud/useCloudLinkController.ts, apps/web/src/cloud/useCloudLinkController.browser.test.tsx	The controller captures recognized relay tunnel-limit failures, exposes the limit, and refreshes usage after link and unlink attempts. The browser test checks the captured limit and error handling.
Account linking and profile usage apps/web/src/components/clerk/useT3ChatLink.ts, apps/web/src/components/clerk/T3ConnectAccountPages.tsx, apps/web/src/components/clerk/T3ChatUserProfilePage.tsx, apps/web/src/components/clerk/T3ConnectUserProfilePage.tsx	The shared hook manages T3 Chat link actions, and the account-page hook accepts a selected page. T3 Chat and T3 Connect profile pages display tunnel usage and related upgrade guidance.
Limit alerts in cloud and settings flows apps/web/src/components/cloud/TunnelUsage.tsx, apps/web/src/components/cloud/ConnectOnboardingDialog.tsx, apps/web/src/components/settings/SavedEnvironmentRows.tsx, apps/web/src/components/settings/settingsSearch.ts	Shared meter and alert components provide usage and limit guidance. Onboarding and settings connect alert actions to account pages, and settings search adds “tunnels limit.”

- Around line 492-493: Update the cloud-link reconciliation flow that refreshes
tunnel usage to clear the `tunnelLimit` refusal state when the refreshed meter
confirms capacity is available, so the `SavedEnvironmentRows` branch no longer
renders `TunnelLimitAlert` after capacity returns.
