TL;DR
testRigor: Plain English test automation for web, mobile, API, and desktop. Free tier to $900/month. Inc. 5000 company. No managed QA option.
Plain English tests are table stakes. The harder problem is who plans coverage, triages failures, and gates releases. Bug0 solves that with a dedicated QA engineer (forward-deployed engineer) for $2,500/mo flat. Engineer, AI platform, and infra all included. 100% critical flows in 1–2 weeks, 0% flake rate. testRigor gives you a tool. Bug0 gives you outcomes.

What is testRigor?
testRigor is an AI-powered test automation platform that lets users write tests in plain English without code or selectors. Founded around 2016 with an AI-first pivot around 2020, they support web, mobile, API, and desktop testing. They made the 2025 Inc. 5000 list of fastest-growing U.S. companies, have $4.1M in funding, and are a YC member.
Pricing: Free tier available. Paid plans up to $900/month. Two editions with different feature sets
Strengths
- +Plain English test creation — no code, no selectors, accessible to non-technical users
- +Broad coverage: web, mobile, API, and desktop testing in one platform
- +Inc. 5000 company — validated real revenue growth
- +Free tier lowers the barrier to adoption
Weaknesses
- −Plain English lowers the bar for writing tests, but your team still runs the full QA process — planning, triage, releases
- −No dedicated QA engineers reviewing results — when tests break, your team investigates
- −Older platform (founded 2016) that added AI later, not AI-native from the start
- −Desktop and mobile testing breadth may mean less depth in web E2E
Common testRigor limitations
testRigor does what it promises. But teams still run into friction:
Tool only — no QA team behind it
Writing tests gets easier with plain English, but someone on your team still plans coverage, manages suites, and triages failures. Bug0 puts a dedicated QA engineer on that
No human verification
Test failures go straight to your engineers to debug. With Bug0, failures are pre-investigated. You get a confirmed bug or a resolved flake, not raw noise
Breadth over depth
testRigor covers web, mobile, API, and desktop. Bug0 focuses on web E2E testing and does it exceptionally well with agentic AI
You still own the process
Even with plain English tests, someone on your team plans coverage, manages suites, and makes release decisions. Bug0 handles all of it
Bug0 vs testRigor
Plain English tests are table stakes now. The real question is who plans, runs, and triages them.
$2,500/mo flat gets you a dedicated QA engineer in your Slack. They plan tests, verify results, file bugs with repro steps, and gate your releases.
Your dedicated QA engineer owns your QA: plans coverage, writes tests, verifies runs, files actionable bugs, gates releases, and syncs weekly
0% flake rate. Tests auto-heal when your UI changes, without anyone touching them
100% critical user flows in 1–2 weeks, full app in 4 weeks. No dependency on your team's bandwidth
Failed tests are reviewed by a real engineer before they reach your team
Flat $2,500/mo. Engineer + tool + AI + infra included
Choose testRigor if
- You need mobile, API, or desktop testing in addition to web
- You want a free tier to experiment before committing
- Your team can own the entire testing process without managed support
Choose Bug0 if
- You want a dedicated QA engineer handling everything for $2,500/mo flat
- You want 100% critical user flows covered in 1–2 weeks without taxing your engineering team
- You focus on web E2E and want the deepest AI-powered solution for it
- You need human-verified bug reports, not just automated pass/fail
- Note: Bug0 is web E2E only. No mobile, API, or desktop testing. testRigor covers more platforms if you need that breadth

Managed
Your dedicated AI QA engineer
A forward-deployed engineer plus AI that reasons through your UI. It maps your flows, handles 2FA, and re-resolves steps from intent when your UI changes, before you even get the Slack alert.

What engineering leaders say.
“Bug0 is the AI QA platform behind Prospyr, the practice management software for aesthetics clinics. It tests our web app continuously and points us to exactly where the app broke when something fails. We catch issues early instead of in production, which keeps a HIPAA-compliant product stable.”
“Bug0 is the closest thing to plug-and-play QA testing at scale. It's helped us catch multiple bugs before they made it to prod.”
“We build healthcare compliance software, so accuracy and reliability are non-negotiable. Bug0 provided us with an AI-based QA layer without adding headcount or another tool for my team to learn and manage. The tests run against all of our QA instances on a regular basis, providing us with a level of coverage and confidence that previously required many resources. We can focus our team on new development and real issues, and that's the part I care most about.”
“We plugged Bug0 into our CI and had our critical flows covered within a week. Like having a proactive QA engineer reviewing every deploy.”
“Bug0 is the AI QA platform behind Ferra, AI estimating software for steel construction. AI-based testing and execution with a forward deployed engineer who verifies every result, so we catch real bugs before production instead of chasing false positives. We see exactly where things broke, and we ship with confidence.”
“Bug0 gives us the speed of AI-native automation with the accuracy of human QA. We stopped worrying about flaky tests entirely.”
“We'd been putting off test coverage for months. Bug0 had our critical flows covered in under a week. No scripts, no maintenance burden.”
“We used to skip regression tests before releases because they took too long to maintain. Bug0 runs them on every PR now. We haven't shipped a regression in three months.”
AI testing + managed QA.
They sell you a tool. We sell you outcomes.
testRigor gives you plain English tests. Bug0 gives you plain English tests AND a dedicated QA engineer who runs them. 100% critical user flows covered in 1–2 weeks, 0% flake rate. $2,500/mo flat, everything included.
