Understand users
before you ship
Swarm sends AI personas through your product like real users, then tells you where they got stuck and what to fix.
Trusted by product teams that ship fast.
Ask a question. Send the swarm. Fix what they found.
1.Describe the flow
Ask the question you'd put to a room of users and point Swarm at a URL, a localhost port, or screenshots.
2.Send the swarm
Personas work through the flow on their own devices, in their own way, and every step is recorded.
3.Read the findings
In about 10 minutes you get a verdict, ranked findings, and fixes you can send to your tracker.
Example: the question “Can new shoppers check out on kestrel.shop?” is sent to five shopper personas. Three check out; Swarm reports three findings, led by shipping options hiding at 200% zoom.
Personas that behave like people
Every persona has a name, a device, a goal, and a temperament. Some skim, some read every word, some give up after two wrong clicks.
Watch every session
Live Agent runs record each persona in a real browser. Scrub the replay and read what they were thinking at every step.

Findings, not footage
A judge reads every session and ranks what the personas hit by severity and reach. Each finding comes with a suggested fix you can push to Linear, Jira, or GitHub.

Works where you work
Start a test from the web app, your terminal, or let your coding agent run one over MCP while it builds. Localhost works too.

Swarm is an AI-powered UX testing platform. It sends AI personas through your product like real users to surface friction, drop-offs, and usability issues before you ship.
Use the web app, the CLI in your terminal, or the MCP server inside Cursor, Claude Code, or Codex. All three run the same tests and return the same findings.
Traditional studies mean recruiting, scheduling, and waiting days for results. Swarm runs personas through your product in about 10 minutes, so you catch friction before launch instead of after.
Yes. Personas can sign in through agent login or cookie injection to test dashboards, checkouts, and other signed-in pages.
The Free plan includes 5 lifetime runs, Startup is $150 a month, and Enterprise is custom. Free is enough to evaluate Swarm end to end.
