TESTERS.AI / CARBON
Build faster.
Ship with confidence.
AI testing for your code, your website, and your game.
INSIDE THE AGENT YOU ALREADY USE
Your code has an author.
Give it a test manager.
J turns your project context into risk-based tests, investigates issues, and brings back evidence you can act on.
Claude · Codex · Cursor · Antigravity
Free and open source. Pro adds advanced controls and workflows. Your coding agent’s usage charges still apply.

Harness FAQ Setup, compatibility & what to expect
Can I keep my existing tests?
Yes. CARBON can coordinate Selenium, Playwright, Cypress, Vibium, pytest, JUnit, Gherkin and Robot Framework tests through the tools available to your coding agent. It can also work from manual test cases. Keep your existing test investment; configure the required runners and dependencies.
Does it connect to Jira, Xray and TestRail?
CARBON has integrations for Jira issues, Xray Cloud tests and TestRail cases and results. Configure credentials, project scope and permissions first. Reads inform your testing plan; creating or updating external records requires an explicit, reviewed approval. Availability depends on your CARBON edition and setup.
Is CARBON free, and where does it run?
The core harness is free and open source. Run it inside Claude, Codex, Cursor or Antigravity; Pro adds advanced workflows and controls. Docker/stdio MCP on-premises packaging is available for the harness. Your coding agent’s model usage and data-handling terms still apply.
BRING A URL. SET THE DIRECTION.
You steer the run.
AI does the testing.
Choose what matters. CARBON Cloud explores your website, checks user journeys, and collects findings and evidence.
- Steer the scope and testing priorities
- Review reproducible issues and evidence
- Recheck changes and catch regressions
Coverage depends on the target and access you provide.
Cloud FAQ Setup, compatibility & what to expect
What can AI test on my website?
Steer exploratory testing, regression and bug checks, accessibility, security, privacy, performance, content and usability. Coverage depends on the pages, access, configuration and budget you provide. Findings are evidence for the tested scope—not a guarantee that every issue has been found.
Does changing the preview start a test?
No. The coverage selector on this page is a preview. Choose Start a web test to open the actual workspace, provide your URL and testing context, and build your steering plan.
What about private sites or our own infrastructure?
Private targets need an authorized connection and suitable credentials. Talk to us about private-network or on-premise requirements. The local harness Docker package and managed CARBON Cloud are different deployment options; access and integration availability must be confirmed for your setup.
REAL GAMEPLAY. REAL DEVICES.
Learn the game.
Test the experience.
AI explores, plans, plays, and checks outcomes. Watch CARBON control a physical iPhone to play Tetris in a Netflix desktop browser.
Custom-trained gameplay models work with AI exploration and evaluation—not just a scripted replay.
Independent Netflix Games demonstration. No affiliation or endorsement implied.
Recorded run: 1,260 points · 6 lines · 3-minute Time Attack.
Capture gaps are marked. This is evidence for this run, not every game.
Games FAQ Setup, compatibility & what to expect
Is this real gameplay or an animation?
The preview is an 18-second excerpt of a recorded Tetris run: CARBON controlled a physical iPhone paired with a Netflix desktop browser. The full recording is available below the video. Capture gaps are marked.
Can it test any game out of the box?
Not automatically. Supported controls, device access and game-specific learning or model setup are required. The Netflix Tetris demonstration is evidence for that game and run, not universal compatibility. Tell us about your game so we can assess the setup.
What does the Games workflow cover?
AI explores controls and menus, plans around player goals, plays through supported interactions, and evaluates outcomes. Gameplay models work alongside exploration and evaluation components to investigate the player experience.
