Swarm closes the gap between how you test and how your product actually gets used — by mimicking real users and real data, continuously.
No setup · no test scripts · works on any URL
app.acme.com Paste a URL and a fleet of autonomous agents spreads across your app, testing every flow, edge case, and viewport combination your manual QA missed.
We use agents that behave like actual users — not like bots checking HTTP status codes. They fill forms, click through checkout, apply coupons, resize the window, paste emoji into name fields. The bugs they find are real.
Any environment — staging, preview, production. No credentials, no SDK, no setup call.
Dozens of agents fan out simultaneously. You see a live feed as they explore — flows hit, inputs tried, breaks found.
Critical bugs first. Each with repro steps, a screenshot, and a session replay you can paste straight into a ticket.
A one-off bug bash catches what breaks on first use. Data Generators is different — it generates a complete synthetic user population and runs them through your app continuously, around the clock.
Swarm builds a population of synthetic users — different browsers, locales, connection speeds, and behavioral patterns — and cycles them through your product 24/7.
The engine generates realistic form data tailored to your product — emails, names, addresses, payment info, edge-case strings — not just random characters.
Bugs that only emerge after a specific sequence of inputs across thousands of sessions get caught and flagged with the exact session number and data that triggered them.
app.acme.com Click-through rate doesn't tell you where users got stuck. We run the exact same synthetic users through both variants simultaneously and surface friction — the hesitation, the back-button, the form field that makes people quit.
"We were running manual QA for two weeks before launch. Swarm found a checkout bug in Firefox that blocked every single payment. It reproduced immediately. The session replay took 10 minutes to diagnose and fix. I genuinely don't know how we missed it."
