Fix database issues automatically. Polylane finds slow and failing queries, works out why, and writes the fix.
Connect with OAuth. Polylane never touches your rows.

Everything Polylane reads from your PlanetScale organization.
Polylane connects your databases to the services that use them.
- query latency checked
- errors checked
- volume checked
- issue when something is off
Checks your production branches
Query latency, errors and volume on production branches are checked automatically. When something is off, you get an issue.
- connection host matched
- username matched
- checkout its database known
Knows which service uses which branch
Polylane matches connection hosts and usernames, so when checkout slows down it already knows the database behind it.
- slow queries
- failing queries
- latency spikes
Reads Query Insights
During an investigation Polylane pulls the branch's slow queries, failing queries and latency spikes as evidence.
- new branch
- schema change
- migration checked first
Watches schema changes
New branches and schema changes are recorded. When an app breaks after a migration, Polylane checks the migration first.
- bad query or missing index
- fix repo behind the service
Writes the query or index fix
When the cause is a bad query or a missing index, Polylane opens a pull request with the fix on the repo behind the service.
- PlanetScale API read only
- your rows never seen
- DB credentials never held
Never connects to your databases
Polylane reads the PlanetScale API only. It never sees your rows and never holds database credentials.
Use PlanetScale with any coding agent. Polylane connects them.
Connect your agent to Polylane once and it can query PlanetScale alongside the rest of your stack.
Guides for PlanetScale
- Guide PlanetScale MCP Server: Setup and Production Permissions Connect the official PlanetScale MCP Server to Claude Code, Cursor and Codex. Set narrow permissions, inspect Insights and review writes before execution.
- Guide PlanetScale Insights: Debug MySQL and Postgres Queries Use PlanetScale Insights to find slow query patterns, anomalies and errors. Compare MySQL and Postgres features, test an index and close production alert gaps.
- Guide PlanetScale Best Practices: A Production DB Checklist PlanetScale Best Practices for production: compare MySQL and Postgres branching, schema changes, connections, indexes, Insights, backups and engine limits.
- Blog Turn your app into a context graph Agents that run software need a context graph of the app: every resource, what it connects to, the repository that deploys it and the team that owns it. How we built one on Durable Objects, keep it fresh across every provider without polling AWS, decide what counts as a change, and delete from it safely.
Common questions.
Is Polylane an AI SRE for PlanetScale?
It does that job; we call it self-operating software. Polylane keeps your databases and branches in one graph with the services that query them, investigates what breaks and fixes it.
Can Polylane change my databases?
No. Polylane only reads the PlanetScale API, never your rows or your credentials. When the fix is a query or a migration, it goes to your repo for review.
How do database issues show up?
Through the services that use them. When an app slows down, Polylane follows it to the branch behind it and pulls that branch's Query Insights: slow queries, errors and latency spikes.
Does it work with my observability provider?
Yes. Polylane supports all the major observability providers, and you can connect any other through MCP. The full list is on polylane.com/integrations.
What does it cost?
Every plan, price and limit is on polylane.com/pricing.
