Codemind

Codemind writes and tests JavaScript or TypeScript code against acceptance criteria, then returns files to your coding agent for review and planning.

Codemind as a delegated coding service

Codemind is a delegated coding build service used from a coding agent. The agent sends a task, acceptance criteria, and stack; Codemind writes the code, tests it against those criteria, and returns the resulting files and build status. The product is intended to move implementation and testing work outside the agent’s active session while leaving planning and review with the agent.

The service currently builds JavaScript and TypeScript, including Cloudflare Workers, Node, and React work. It can create code, change files supplied with a task, and run reviews or tests on request. A build is verified only when its code passes tests derived from the acceptance criteria; failed builds return an error code and do not incur a charge. Codemind is available through MCP and REST, with support listed for several coding-agent clients.

Title: Codemind as a delegated coding service

Features

Delegated code builds

Send a task with a title, acceptance criteria, and stack. Codemind writes the implementation on its servers instead of making your coding agent handle the full write-run-fix loop.

Acceptance-criteria testing

Tests are written from the acceptance criteria and run before the result is returned. Criteria that are too vague to test are flagged before the build starts.

File delivery with build results

Passing builds return files to the agent, while failed builds return a failed status and error code. Your agent can then retry or handle the task itself.

Verified-build billing

A build that passes its tests is counted as one verified build. Failed builds are not charged, and builds inside the free allowance cost nothing either way.

Existing-file changes and on-request review

Codemind can modify existing files when the current file is sent with the task, and it can perform a code review or test run when requested by the agent.

Concurrent server-side execution

Builds run on Codemind’s servers, allowing the agent to send another task while a build is running. Free accounts support up to two concurrent builds and 20 builds per hour.

Use cases

  • Offload independent implementation tasks

    Give an agent a well-defined feature or issue with acceptance criteria and let Codemind implement and test it while the agent proceeds with planning or another task.

  • Modify existing JavaScript or TypeScript files

    Send an existing file with a change request when a project needs a targeted modification. The completed file is returned to the agent for writing into the project.

  • Build supported application components

    Use Codemind for Cloudflare Workers, Node, or React work where the desired behavior can be expressed as testable criteria before implementation begins.

  • Request focused review or testing

    Ask the agent to request a review or test run when implementation needs an additional check, rather than handling every verification step inside the main coding session.

Pros and Cons

Pros

  • Tests implementation against acceptance criteria before returning a successful result.
  • Failed builds are returned with an error code and are not charged.
  • Runs builds on its servers so the coding agent can continue with other work.
  • Provides a free allowance without requiring a card to start.
  • Supports MCP and REST access, plus several coding-agent clients.

Cons

  • Current language support is limited to JavaScript and TypeScript and the listed JavaScript/TypeScript environments.
  • Paid top-ups are not yet available, so usage beyond the free allowance waits until the next month unless billing availability changes.
  • The quality of verification depends on specific, testable acceptance criteria supplied by the agent.

FAQ

How do I set up Codemind?

Paste Codemind’s setup prompt into a supported coding agent. The agent reads the onboarding instructions, adds the Codemind server to the host, and asks you to reload it. A free account is created when it connects. You can also add the MCP server manually with an API key.

What happens during a delegated build?

Your agent sends a task title, acceptance criteria, and stack. Codemind writes the code and tests it against criteria derived from the request. A passing build returns the files and a verified result; a failed build returns a failed status with an error code and no charge.

Which languages and environments does Codemind support?

Codemind currently builds JavaScript and TypeScript, including work for Cloudflare Workers, Node, and React. Other languages are not currently supported.

How does Codemind’s pricing and allowance work?

The Free allowance includes 100 verified builds in the first month and 50 each month afterward, with up to two builds at once and 20 per hour. After the allowance, the listed price is $0.10 per verified build, but paid top-ups are not yet available. New builds are refused after the allowance until the next month begins unless paid billing has become available.

Which agents and connection methods can I use?

Codemind can be used through supported coding agents over MCP, or through REST from your own code. The site lists Claude Code, Cursor via its agent CLI, Codex CLI 0.160.1 or later, and OpenCode as supported; Cline is listed as coming soon.
