FLY.IO SUNSET HITS DASHBOARD, CLI DROPS TIMEOUT BOTTLENECK

By RepoJournal · Filed 06:03 UTC on May 12, 2026 · About Supabase

Supabase is surfacing the Fly.io May 31 suspension directly in Studio with per-project impact breakdown, while the CLI finally kills the 10-second upload timeout that was choking storage streaming.

The Studio team shipped a self-correcting Fly.io deprecation banner [1] that shows affected projects and vanishes automatically once users migrate off the platform — no manual cleanup required. Meanwhile, the CLI fixed a critical bottleneck: storage uploads were timing out under load because the service gateway inherited a 10s timeout from legacy health-check code [2]. This wasn't a design choice; it was technical debt from code extraction years ago. On the frontend, Studio is hardening against React 19 regressions [3] by fixing four patterns that break under the new version today but pass on React 18 — landing the fixes now so the eventual upgrade is seamless instead of a separate cleanup pass. The CLI also shipped the TypeScript implementation of `supabase functions dev` [4], giving developers a managed local Supabase stack with Edge Runtime, file watching, and hot reload in a single command. Separately, domain hygiene: Supabase updated security documentation to use `supabase.com` instead of the legacy `supabase.io` address [5], ensuring researchers file disclosures to the right inbox.

Action items

→ Upgrade CLI to latest and test storage uploads — the timeout fix unblocks streaming supabase/cli [immediate]
→ Check Studio for the Fly.io banner if you have projects on that platform — plan migrations before May 31 supabase/supabase [plan]
→ Try `supabase functions dev` if you're running the TypeScript CLI — local development just got faster supabase/cli [monitor]
