Send coding work
to the cloud.

Launchstack gives each coding agent an isolated branch and a cloud development environment. Use it to build features, fix bugs, run tests, and prepare pull requests without tying up your laptop.

Give it a task, not a code snippet.

Ask Launchstack to trace a bug, add a feature, update a dependency, or repair a failing build. The agent can inspect the repository, edit files, run commands, and verify its work in one session.

  • Build features across multiple files
  • Investigate bugs before changing code
  • Run type checks and tests before handoff

Keep agent work off your machine.

Every session gets an isolated cloud sandbox and its own Git branch. Agents can install dependencies, start development servers, and test changes without competing for your local files or compute.

  • Run several tasks on separate branches
  • Preview changes before they reach your codebase
  • Hibernate inactive sandboxes and restore their files

Come back when the work is ready.

Launchstack runs each agent turn as a durable workflow. You can leave the page, reconnect from another device, and continue following the same run instead of keeping a browser tab and local process alive.

  • Resume long tasks after an interruption
  • Review the diff and share a read-only session
  • Optionally commit, push, and open a pull request

From task to pull request.

Launchstack gives the agent everything it needs to do the work in the cloud, then brings you back a tested, reviewable change.

can take on.

Use it for contained engineering tasks with a clear finish line. Every task stays isolated, produces a reviewable diff, and can move from request to pull request in the cloud.

001

Feature work

Hand off a scoped feature that touches components, APIs, tests, or configuration. The agent works across the repository and checks the result.

Starter prompt

Implement [feature] in this repository. First inspect the existing architecture and conventions. Make the smallest complete change, add or update relevant tests, and run the project's lint, type-check, and test commands before summarizing the result.

002

Bug fixes

Send an error, failing test, or broken flow. The agent searches for the cause, makes a targeted change, and runs the relevant checks.

Starter prompt

Review the current branch for bugs and regressions. Trace each issue to its root cause, prioritize findings by user impact, and fix confirmed problems with targeted changes. Run the relevant tests and report what you verified.

003

CI repair

Give an agent a failing check to investigate. It can inspect logs, update the branch, and rerun the same project commands before you review it.

Starter prompt

Investigate the failing CI checks on this branch. Reproduce each failure locally, identify whether it comes from the branch or the baseline, and fix only branch-related issues. Rerun the same checks CI uses and summarize any failures that remain.

004

Parallel backlog

Start separate sessions for independent tasks. Each one gets its own sandbox and branch, so work can move at the same time without file conflicts.

Starter prompt

Take ownership of [backlog task]. Keep the work limited to this task, preserve unrelated changes, and follow the repository's existing patterns. Verify the completed path and leave the branch ready for review with a concise summary of files changed and checks run.

Pro subscription

Your AI, free. Managed AI, optional.

Pro is optional for users who want Launchstack to manage their AI usage. The allowances below apply to each paid monthly billing period.

Use your Codex subscription or an OpenRouter key for free, or choose Pro to get included AI usage and more cloud workspace time.

Launchstack Pro

$29USD / month

  • AI usage included each month; no API key needed to start
  • 25 hours of running sandbox time per paid period
  • Up to 2 concurrently running sandboxes
  • OpenRouter bring-your-own-key fallback; your provider bills that usage separately

Monthly renewal. No free trial, annual commitment, metered overages, or allowance rollover. Applicable tax is shown at checkout. Managed inference and sandbox time are separate limits; sandbox time measures running wall-clock time, including waits.
