Quality engineering platform

Your test suite uses
fake data.
Your users don't.

Swarm closes the gap between how you test and how your product actually gets used — by mimicking real users and real data, continuously.

Bug Bash
Autonomous agents run your app, find bugs, and file replay-ready reports — before your users do.
02
24/7 Data Generators
Realistic synthetic users and data running through your product continuously, day and night.
03
A/B Testing
The same synthetic users, both variants, simultaneously. Real friction scores — not just click rates.
Product 01 — Bug Bash

Deploy without the pre-launch panic.

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.

Dozens of agents fan out simultaneously. You see a live feed as they explore — flows hit, inputs tried, breaks found.

Product 02 — 24/7 Data Generators

Some bugs need 10,000 sessions to show up.

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.

Realistic persona generation

Swarm builds a population of synthetic users — different browsers, locales, connection speeds, and behavioral patterns — and cycles them through your product 24/7.

Domain-specific synthetic data

The engine generates realistic form data tailored to your product — emails, names, addresses, payment info, edge-case strings — not just random characters.

Latent bug detection

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.

Product 03 — A/B Testing

Stop guessing which variant converts.

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."
