The platform

Autonomous quality engineering for web apps.

Otto is a team of AI agents that plans, writes, runs, and heals your end-to-end tests, learns from every run, and grades its own work — turning a plain-English goal into coverage you can trust.

How it works

One run, seven agents.

Each agent owns one job and hands off to the next. You give a goal; the team does the rest — from deciding what to test to grading its own work.

1

🔍 Scanner

Reads your app to learn its stack, structure, and where sign-in lives.

2

💡 Proposer

Turns your PRDs and specs into prioritized candidate tests, with coverage gaps flagged.

3

🗺️ Planner

Designs each test: the steps, the data it needs, and what counts as success.

4

✍️ Generator

Writes the test by exploring the live app — no recording, no scripting.

5

🩹 Healer

Repairs tests when the UI changes, then re-runs to confirm the fix.

6

🧠 Analyzer learns

Turns every run into lessons, and keeps the ones that make the next run better.

7

🛡️ Auditor QA of QA

Scores how well every agent planned, wrote, and healed each test.

Coverage you can trust

Know what's tested — before you ship.

Point Otto at your PRDs, design docs, and specs. It reads them and proposes the test cases they imply — each prioritized and mapped against what's already covered, so decision-makers see the gaps that carry the most deployment risk instead of finding them in production.

Soon Pull requirements & production defects straight from Jira.

Self-healing

Tests that fix themselves when your app changes.

Selectors move, workflows evolve, interfaces get redesigned — and normally someone spends their Friday fixing red automation. Otto diagnoses the break, repairs the test on its own, and re-runs to confirm the fix still checks the same outcome.

Self-improving

It gets better at your app every run.

Most automation decays — every UI change chips away at it. Otto does the opposite: it turns each run into lessons, keeps only the ones that prove they make the next run better, and gets steadier the longer it tests your app. Coverage that compounds instead of rotting.

QA of QA

If AI tests your software, something should test the AI.

When the testing decisions are made by AI, you need to know those decisions were any good. Otto's Auditor scores every plan, test, and repair on a 0–100 quality index, and flags anti-patterns like empty or vacuous checks — so you can trust the autonomy instead of taking it on faith.

Model independence

Always on the right model — and on Enterprise, your own.

We run every agent on top-tier models and keep you current as better ones ship — higher plans get the newest models first. On a dedicated or Enterprise deployment, bring your own models, keys, and private endpoint, so you control which AI your data is sent to — right down to a fully private, in-environment model.

Real apps, handled

Sign-in and test data, solved.

Real apps live behind a login and run on real data. Otto signs in as each user role your tests need — with stored credentials, multi-step flows, and ready-made recipes for identity providers like Okta and Login.gov.

Bring your test data as a simple table or a CSV upload, and mark rows single-use so two runs never grab the same one — no more flaky tests fighting over the same account.

After the run

Results you can act on — not just pass or fail.

Every run is triaged, trended, and explained, so you know what broke, whether it's new, and exactly where to look.

Fits your workflow

Plugs into where you already work.

Trigger runs from GitHub on every pull request and deploy — Otto posts the verdict back as a native status check and can open an issue when something breaks. Any CI can also trigger runs through the API.

Send results to the Slack channels you choose, routed by app and event. Scheduled and recurring runs keep coverage fresh without anyone pressing go.

Enterprise & trust

Built for teams that answer to security.

The controls a CISO asks for, and the deployment options a regulated team needs.

Workspaces, teams & roles

Organize work by team and environment, with role-based access across your whole organization.

Audit log

Every meaningful action is recorded with who, what, and when — for the reviews that matter.

Single sign-on Enterprise

SSO and SAML so access follows your existing identity provider and offboarding.

Dedicated or self-hosted Enterprise

Run Otto as a dedicated instance, or inside your own cloud, when that's what compliance requires.

Bring your own model Enterprise

Your providers, your keys, your private endpoint — so your quality platform never dictates your AI strategy.

Your data stays put

On a self-hosted deployment, Otto and its data run inside your environment — and a private model keeps your prompts there too.
