What Supabase does

TLS compatibility, reviewed October 12: Supabase plans to remove four CBC-mode TLS 1.2 cipher suites from managed project HTTP APIs no earlier than November 10, 2026. Auth, Data API, Storage, Realtime and Edge Functions share that boundary. Other supported TLS 1.2 ciphers and TLS 1.3 remain; direct Postgres, pooler and Management API connections, and self-hosted deployments, are excluded. This is a future compatibility change, not a current outage.
Supabase is a Postgres development platform that combines database, generated data APIs, authentication, file storage, and related backend services.
Status notification maintenance, reviewed October 10: Supabase's October 8 announcement moves status.supabase.com to incident.io without changing the URL. Email subscriptions were transferred automatically; existing Slack and RSS subscriptions need a fresh subscription. SMS and webhook subscriptions did not transfer and those notification channels are no longer offered. The replacement supports Email, RSS and Slack, with product and region choices for email. The announcement states that self-hosted deployments are unaffected; this is a status-notification change, not a database migration or outage announcement.
Framework adapter deadline: the October 5, 2026 announcement deprecates @supabase/server/adapters/hono, /h3, /elysia and /nestjs; they still work but are scheduled for removal on December 1, 2026. withSupabase(config, handler) is not deprecated, nor are withSupabase(config) and @supabase/server/middleware/* entries. This is not the retirement of Supabase Auth or the database service.
Authentication migration red line: an adapter using auth: 'user' must retain a required gate such as withRequiredClaims(), not optional withClaims(), which accepts anonymous requests with jwtClaims: null. For auth: 'publishable' and auth: 'secret', the announcement directs endpoints to stay on withSupabase because no bridge entry replaces those modes. auth: 'none' needs no gate; inventory each registration rather than applying one blanket replacement.
October 7 review: Supabase's October 6 announcement makes scoped personal access tokens (PATs) generally available for Management API, MCP and CLI integrations. Tokens can target selected projects in one organization or all projects in selected organizations, with capability-level permissions and expiry up to one year. Access cannot be edited after creation, and the user's current role still limits it. Existing tokens are not automatically revoked; the browser flow for supabase login still creates an account-level token. Scoped CLI authentication instead uses login --token or SUPABASE_ACCESS_TOKEN; supabase whoami does not support project- or organization-scoped tokens.
MCP permission examples from the PAT documentation: get_logs and query_logs need Logs Read; execute_sql needs Database Read and stays read-only without Database Read/Write; apply_migration needs Migrations Read/Write. A tool's confirmation prompt is separate from the token permission. Read-only access can still disclose sensitive results, so least privilege includes the selected project and the permitted data, not only the absence of writes.
Do not confuse management PATs with application API keys. A publishable key is intended for client-side use with application authorization and RLS; secret keys and legacy service_role keys bypass RLS and belong only in controlled server environments. A scoped PAT is not a replacement for application authentication or row-level policies, and no management token belongs in browser bundles.
October 1, 2026: OrioleDB enters Public Beta, including Pro, Team and Enterprise projects, with standard Postgres project billing. Supabase describes it as testing-only, not recommended for production, and without an SLA. Paid availability is not a production-readiness guarantee.
OrioleDB is selected when creating a project; it cannot be added to an existing project or removed later. Scheduled backups are supported, but Point-in-Time Recovery (PITR) and restoring a backup to a new project are unavailable. Existing alpha projects are not automatically moved to Public Beta. OrioleDB is not yet part of the self-hosted Supabase stack; the separately documented standalone Postgres image is a different scope.
Postgres upgrade checkpoint: Supabase's September 25, 2026 notice covers 15.19 / 17.11. From September 28, new projects use these versions and existing projects can upgrade in the dashboard. Self-hosted deployments can also be affected; this is separate from the logs API migration below.
Affected cases: older ltree indexes with multibyte/non-libc collation, or very deep paths; btree_gist float indexes containing possible NaN values; pgcrypto PGP data using bf/blowfish/cast5; and custom operators with non-built-in selectivity estimators. Indexes may return incomplete results. Legacy-cipher data was effectively unencrypted and stops decrypting by default after upgrade; default AES is not affected. Existing custom operators still work, but recreating them requires superuser. Extension-installed operators are excluded.
Supabase's July 23, 2026 announcement schedules removal of the Management API logs.all analytics endpoint for September 23, 2026. Its replacement, logs, accepts ClickHouse SQL and queries a unified logs table, with source_name selecting a log source and log_attributes replacing nested metadata traversal. This concerns managed log querying, not removal of Postgres or the application data APIs; the announcement marks self-hosted deployments as unaffected.
The migration notice also covers AI agents calling the Supabase MCP server's get_logs tool, which previously used logs.all internally. Supabase identifies mcp-server-supabase v0.10.0 as using the replacement endpoint. Dashboard Logs Explorer users are not affected by this endpoint removal. This is additional scope from the existing announcement, not a newly announced outage.
Supabase MCP server v0.13.0 adds a separate upgrade consideration: createSupabaseMcpServer renames its costConfirmation option to confirmation, a breaking change for integrations using that option. Confirmation now also covers destructive SQL in execute_sql and apply_migration; the local HTTP entry point opts in both tools. This does not replace the earlier get_logs migration.
SQL confirmation requires the relevant tools to be enabled in the confirmation configuration and a client supporting form elicitation. Supabase's implementation notes describe the regex detector as best-effort, not a security barrier: some destructive statements can be missed, and clients without elicitation support can execute SQL without a prompt. Hosted-platform SQL opt-in is separately feature-flagged; the package release alone does not establish your hosted project's behavior.
It covers a major backend stage in an AI-built application, but schema design, authorization policies, migrations, backups, observability, and data ownership remain operator decisions.
