Sign-ups are failing and auth looks fine. Polylane finds the layer that actually broke.
Polylane connects your database, auth, storage and edge functions in one graph, and reads Supabase's own logs, so an auth error gets traced to the database that caused it.

What Polylane reads from each Supabase project.
Project Postgres Database Connection Pooler Edge Function Database Branch Storage Bucket Auth Service Storage Service Realtime Service REST API Custom Domain Secret Network Restrictions Auth, storage, functions and Postgres, all in view.
Every part of the project, linked
Every project lands in the graph with its databases, branches, edge functions and buckets, plus the auth, storage and realtime services behind them. When one layer fails, Polylane can see the others.
Linked to the apps that use them
Polylane spots Supabase hosts in environment variables across your other clouds, so it already knows which service talks to which project. When checkout breaks, the project behind it is already in the picture.
Watching what Supabase reports
Polylane watches edge 5xx rates, Postgres error logs, auth failures, function errors and service health, judged against how each project normally behaves. No thresholds to tune.
Every log Supabase keeps
Edge, function, Postgres, auth, storage and realtime logs become evidence in investigations, alongside the security and performance advisors Supabase already runs on your projects.
Your rows stay yours
Polylane reads the Supabase Management API and nothing else. It never connects to your databases, never sees your rows and never stores project API keys. Your credentials are encrypted before they're stored.
The migration that broke it, fixed
When the cause is a bad migration, a misconfigured function or a line of code, Polylane writes the fix on the repo behind the app, with the evidence attached.
These prompts already work. Copy one, swap your own service name in, and run it.
Give it to your coding agent and let it cook.
“We're renaming the orders table tonight. Which services, queries, and crons touch it?” 
“Map our AWS account: what's running, what depends on what, and what's critical?” 
“Find the risky configuration: public buckets, missing alarms, single points of failure.” Use Supabase with any coding agent. Polylane connects them.
Connect your agent to Polylane once and it can query Supabase alongside the rest of your stack.

Common questions.
Is Polylane an AI SRE for Supabase?
It does that job; we call it self-operating software. Polylane keeps your projects, edge functions, branches and storage in one graph, investigates what breaks and fixes it with your approval.
How does Polylane connect to my Supabase organization?
With OAuth or a personal access token: approve in Supabase, or paste a token. Either way it's encrypted before it's stored.
What Supabase resources does Polylane sync?
Projects, Postgres databases, connection poolers, database branches, edge functions, storage buckets, the auth, storage, and realtime services, REST APIs, custom domains, secrets, and network restrictions. The full list is on this page.
Can Polylane change my Supabase projects?
Polylane investigates and explains. Code fixes go to the repo behind the project for your review, and any write against Supabase waits for your approval unless you've allowed it ahead of time.
How does detection work without alert rules?
Polylane reads each project's logs and health signals regularly and compares them with that project's normal: edge 5xx, Postgres errors, auth failures, function errors, request volume and advisor findings.
Does it work with my observability provider?
Yes: Datadog, Sentry, Honeycomb, Axiom, Grafana Cloud, Logfire, Better Stack and OpenStatus. Forward their alerts and Polylane triages each one.
What does it cost?
There's a free plan, and paid plans start at $80 a month. On Scale and above you can switch on pay-as-you-go beyond the included credits. Every limit is published at polylane.com/pricing.
