What is TryCase?

TryCase provides disposable environments for LLMs to run apps, verify changes, and capture screenshots, recordings, logs, and artifacts for testing and debugging. It allows developers to programmatically launch isolated Linux environments, upload repositories, execute commands, and interact with web browsers for automated testing. The tool is designed to iterate on failing flows until they pass, making it a robust solution for AI-driven testing and debugging workflows.

Application scenarios

  • Automated regression testing

    Run app builds and verify UI flows with browser automation, capturing screenshots and recordings for proof.

  • AI agent debugging

    Let an agent automatically fix failures and retest until the flow passes, reducing manual intervention.

  • CI/CD pipeline validation

    Integrate disposable environments into continuous integration to test code changes before deployment.

  • End-to-end (E2E) testing

    Simulate user interactions like clicking buttons, filling forms, and checking for expected results (e.g., "Order confirmed").

  • Log and artifact collection

    Capture detailed logs, screenshots, and video recordings of test runs for post-mortem analysis.

  • Multi-step workflow iteration

    Upload a repo, install dependencies, start a dev server, and run browser tests in a single scripted sequence.

Core Features

  • Disposable environment launch

    Spin up a fresh Linux environment with a single API call (`trycase.launch({ os: "linux" })`).

  • Repository upload

    Upload a code repository directly into the environment for testing.

  • Command execution

    Run any shell command (e.g., `bun install && bun dev`) inside the environment.

  • Browser automation

    Open a browser, click elements by selector, fill form fields, and assert page content (e.g., `browser.expect(page).toShow("Order confirmed")`).

  • Recording and proof capture

    Record test sessions with video and take screenshots via `env.record({ video: true })`.

  • Log retrieval

    Access the last 200 lines of logs with `env.logs.tail(200)` for debugging.

  • Automated retesting

    Loop through failing flows, have an agent fix the issue, and retest until the result passes.

Target users

  • Software developers who need to test app builds in isolated environments.
  • QA engineers looking to automate E2E testing with browser interactions and visual proof.
  • AI/ML engineers building agents that can debug and retest code autonomously.
  • DevOps teams integrating disposable test environments into CI/CD pipelines.

How to use TryCase?

To use TryCase, developers write code that calls the TryCase API. The typical workflow involves launching an environment, uploading a repository, executing setup commands, opening a browser, performing user actions, recording the session, and checking for expected outcomes. If a test fails, the tool can iterate with an agent fixing the failure and retesting. Detailed documentation and examples are available on the official website.

Effect review

TryCase offers a pragmatic, code-first approach to disposable testing environments that feels purpose-built for AI-assisted debugging. The ability to script an entire test cycle—from environment launch to browser interaction to log collection—makes it highly efficient for repetitive validation tasks. The retesting loop, where an agent automatically fixes failures, is a standout feature that could significantly reduce manual debugging time. While the tool is clearly developer-focused and requires coding skills, its direct API design and focus on proof (screenshots, video, logs) make it a strong candidate for teams already using automation in their workflows. The lack of a visual UI or no-code option may limit its appeal to non-technical testers, but for those comfortable with code, it delivers exactly what it promises.

Frequently Asked Questions

What is TryCase?
TryCase provides disposable environments for LLMs to run apps, verify changes, and capture screenshots, recordings, logs, and artifacts for testing and debugging.
How do disposable environments work?
Each time you run a test, TryCase spins up a fresh, isolated environment that is automatically destroyed after use, ensuring no state leakage between runs.
What types of artifacts can I capture?
You can capture screenshots, screen recordings, logs, and other artifacts generated during app execution for thorough debugging and verification.
Can TryCase be integrated with CI/CD pipelines?
Yes, TryCase offers APIs and CLI tools that allow seamless integration with continuous integration and deployment workflows.
Is TryCase suitable for non-LLM applications?
While designed for LLM-driven apps, TryCase can be used for any application that requires ephemeral test environments and artifact capture.
