Ten deploys a day. One of them breaks. Polylane catches it, works out why, and fixes it.
Vercel made deploying disappear. Polylane does the same for everything that comes after: watching, debugging, and fixing production.

Projects, domains and deploys, linked
Projects, deployments, domains, Edge Config, Postgres, KV, Blob and firewall rules all sit in one graph with their history. Polylane knows which project a domain serves, and which DNS record on another provider points at it.
Webhooks keep the graph current
The moment you ship, the graph knows: what deployed, which domain moved, what config changed. When production breaks right after, the investigation starts from that deploy.
Alerts triaged on arrival
Polylane picks up every failed deployment and alert as it lands, judges it against how the project normally behaves, and folds repeats into one issue instead of pinging you for each one.
Misconfigurations surfaced early
Polylane flags domains pointed at the wrong project, certificates about to expire and environments drifting apart. Each shows up on the resource it affects, saying whether Polylane can fix it in place or what you should do.
OAuth from the Marketplace
Polylane installs from the Vercel Marketplace: pick the team, choose which projects it can see, and you're done. Polylane investigates and explains, and any write action waits for your approval unless you've allowed it ahead of time.
It knows which deploy did it
Polylane compares the signals most at risk before and after every deployment or config change. When the cause is a line of code, it writes the permanent fix on the repo behind the project.
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.
“Review PR #241 against production: what does it deploy to, and what breaks if it merges?” 
“If checkout-api goes down, what goes down with it? Walk the graph and rank by traffic.” 
“List every deploy since Friday and flag the ones whose metrics moved afterwards.” 
“P99 on checkout-api doubled at 14:10. Find the cause and show the evidence.” Use Vercel with any coding agent. Polylane connects them.
Connect your agent to Polylane once and it can query Vercel alongside the rest of your stack.

Common questions.
Is Polylane an AI SRE for Vercel?
It does that work, though we call it self-operating software. Polylane keeps your projects, deployments and domains in one graph, investigates what breaks and fixes it with your approval, so the project looks after itself.
How does Polylane connect to my Vercel account?
Through the Polylane integration on the Vercel Marketplace, over OAuth: no API keys to create or rotate. Pick the team, choose which projects it can read, install.
What Vercel resources does Polylane sync?
Projects, deployments, domains, Edge Config, Postgres, KV stores, Blob stores, log drains, custom environments, firewall configuration, webhooks, and integrations. The full list is on this page.
Can Polylane change my Vercel projects?
Only with your approval, or where you've allowed it ahead of time. Polylane investigates and explains, code fixes go to the repo behind the project for your review, and any other write against Vercel pauses until you approve it.
How does detection work without alert rules?
Polylane triages every deployment event and alert the moment it lands, and judges each signal against how the project normally behaves. No thresholds to configure.
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.
