TryCase
Disposable cloud test environments for AI coding agents.
TryCase gives AI coding agents isolated cloud Linux environments to run apps, test changes, and capture visual proof — screenshots and recordings — so they return verified results instead of unconfirmed code.
What is TryCase?
TryCase is a service that provides disposable, isolated Linux environments in the cloud where AI coding agents can run and test an application before handing work back to a human. Agents get a throwaway Linux desktop with a terminal and browser control, exercise the app like a real user, and return screenshots, video recordings, logs, and artifacts as proof the change actually works; the environment is destroyed afterward. Its stated principle is that agents should only say done once they've actually run and verified the work.
Key features
- Disposable, isolated Linux desktop environments spun up in the cloud for each test run
- Browser control that clicks, fills forms, and asserts expected outputs
- Automatic screenshot and video-recording capture during the run
- Log collection and tail for inspecting what the app did
- Returns screenshots, recordings, logs, and artifacts alongside the answer
- Environment is automatically destroyed after the run
- Desktop mode with take-control links for manual login scenarios
- Port-collision prevention across multiple concurrent agent runs
Who it's for
- Coding agents (Claude, Codex, Cursor) that need to verify a change end-to-end before a human reviews it
- Developers who want proof-of-testing artifacts instead of an agent claiming success from transcripts alone
- Testing full user flows like clicking through a UI or filling forms in a running app
- Catching failures and letting the agent iterate on fixes until tests pass
When not to use it
If you only need static checks like unit tests, linting, or type-checking in your own CI, or your app can't run in a disposable cloud Linux desktop, a full throwaway browser-testing environment is more than you need.
FAQ
Which AI coding agents does TryCase work with?
It works with Claude, Codex, Cursor, or any coding agent. You install its skills via `npx skills add bencsn/trycase-skills`, and agents that don't support skills can fall back to using the CLI directly.
How do I set it up?
Run the install command `npx skills add bencsn/trycase-skills --skill trycase-cli --skill trycase-run-linux-app -g`. The agent then gets a disposable Linux desktop with a terminal and browser control it drives through CLI commands.
What environments does it provide?
Cloud-based, isolated, disposable Linux desktop environments (specified as os: linux in API calls), each with a terminal and browser so an agent can run and test an app like a real user.
How does verification and screenshot capture work?
The agent runs the app, controls the browser to click/fill forms and assert outputs, and the run returns screenshots, video recordings, logs, and artifacts as proof. On failures the agent can iterate until tests pass.
Is it secure and isolated?
Each run happens in an isolated, disposable environment that is automatically destroyed afterward. It also prevents port collisions across concurrent agent runs and supports deliberately passing secrets/credentials into a run.
How much does TryCase cost?
The site has a Pricing page and its Product Hunt listing notes free options are available, but specific paid tiers and prices are not detailed in the public marketing content.
