Everything an agent does, included.
Every core capability ships standard out of the box with every agent.
- PR diff analysisEvery pushYou don't manually review what changed — O2 does it. Diff-aware impact mapping across every branch.
- Impact radius mappingPer PROnly flows touched by the change are tested.
- Journey-based test plansAutomaticPlans generated from real user journeys, not coverage heuristics. Written and updated natively.
- CI executionBefore mergeBugs are caught in the PR, not in production. Native runners for GitHub, GitLab, Bitbucket, CircleCI.
- Pre-merge checksAutomaticFailing PRs are blocked — no manual sign-off required. Regressions blocked with explainable signals.
- Per-PR reportsEvery runPass/fail + screenshots posted on the PR — no log-diving
One Agent. Five Stages. Every PR.
The agent works through each PR sequentially — one stage at a time, completing the entire testing workflow before your team reviews the code
Diff analysis
The agent reads the PR diff and builds a complete picture of what changed — which files, which functions, and which data paths.
Blast radius mapping
It traces how those changes flow through your codebase and identifies every user journey that could be affected — nothing more, nothing less.
Test generation
The agent writes targeted tests for the impacted flows natively. No pre-existing test suite required. No boilerplate scripts to write or maintain.
CI execution
Tests run in CI before the PR is mergeable. Bugs surface as real failures — with screenshots and a full trace — not after the fact in production.
PR status update
Results are posted directly on the pull request — pass/fail status, which flows were tested, any bugs found. Your team sees exactly what was validated before they approve.
Finds bugs faster than a QA engineer.
A QA engineer reviews PRs manually — reading code, building test cases, running checks, filing bugs. O2 does the same workflow automatically, on every PR, in under 30 minutes.
QA Engineer
- Writes and maintains regression test scripts manually
- Review velocity varies wildly — code branches wait in queue
- Linearly scales with headcount as your absolute PR volume grows
- Framework scripts break continuously whenever UI selectors change
- Strong execution at exploratory user flows and custom edge cases
DevAssure O2
- Generates and executes tests automatically — completely scriptless
- Results on every PR in under 30 minutes
- Scales with PRs, not people
- Zero test maintenance as your codebase evolves
- Frees your team for exploratory work and edge cases
DevAssure is built around developers — it reads your code diff, figures out what changed, and generates + runs tests automatically with no human recording step.
DevAssure’s Invisible Agent transformed how we approach testing. Instead of constantly writing and fixing brittle scripts, the agent understands our workflows and executes tests autonomously. The biggest impact for us has been near-zero test maintenance, highly reliable runs with virtually no flakiness, and the ability to test directly inside VS Code without disrupting developer flow.

Frequently asked questions
Everything you need to know about DevAssure, PR testing, and CI integration.
One O2 agent works through your full PR testing workflow sequentially — it analyzes the diff, maps blast radius, generates tests, executes them in CI, and posts results on the PR. It completes the entire workflow end to end for each PR, one stage at a time, with full focus on each step. There are no per-PR charges, no usage caps, and no restrictions on how you use it.
Most runs complete in under 30 minutes. Because the agent maps blast radius first — identifying only the flows affected by the specific PR — it runs a targeted set of tests rather than your full suite. That means bugs surface faster, while the PR is still open, not after it merges.
Yes. DevAssure ships an official GitHub Action that drops into your existing workflow. Add one YAML file and a DEVASSURE_TOKEN secret — no framework migration required. It also supports GitLab CI and CircleCI via the CLI.
Blast radius refers to the set of user flows and application areas that could be affected by a specific code change. DevAssure O2 maps the blast radius of every PR by tracing how changed files flow through dependencies, then runs tests only on the impacted flows — keeping runs fast without sacrificing coverage.
Yes, you can cancel your subscription at any time. There are no long-term contracts or commitments.
No. You can assign an agent to any codebase, workflow, or team structure that works for you — by repo, by service, by squad, or by product. There are no restrictions on number of PRs, test runs, or test cases per agent.
No. O2 reads your PR diff, maps which user flows could be affected, and generates the tests automatically. You do not need Playwright scripts, Cypress specs, or a pre-built test library to get started.
No. O2 handles the automated validation of code changes on every PR — it generates and runs targeted tests so your team does not have to write or maintain test scripts. QA engineers can focus on exploratory testing, edge cases, and quality strategy instead of script maintenance.
Yes. DevAssure can run inside GitHub Actions so pull requests are validated automatically in CI. Teams can start with the official GitHub Action or run the CLI in their existing pipeline.
