What you can build

  • Build a catalog generator that takes Coder Terraform templates and outputs a searchable inventory of declared infrastructure types and template descriptions.
  • Build a linter that takes Terraform workspace templates and a team-authored policy file, then outputs violations such as disallowed resource types.
  • Build a diff tool that takes two Terraform template revisions and outputs changed resource declarations for an operator’s review.
  • Build a checker that takes a repository’s devcontainer.json and outputs a compatibility checklist for Coder use with Docker, Kubernetes, or OpenShift.
  • Build a workflow that takes an issue and project-specific checks, then outputs a scoped coding-agent brief and a human review checklist.

Try this prompt

Build a small Terraform template revision report tool. Take two versions of a Coder workspace template as input, identify changed resource declarations, and produce a readable change report for operator review. Preserve both input versions and the generated report. Add tests using sample Terraform templates, handle unreadable or invalid inputs with clear errors, and document that the report is advisory and does not apply changes or provision infrastructure.

Get started

  1. Choose an installation path

    Use Coder’s official installation guides for deployment options, or follow the README quickstart for an evaluation on Linux, macOS, or Windows: https://coder.com/docs/install

  2. Plan production hosting

    For production, provide PostgreSQL 13 or later and an external access URL. Review the documented sizing and infrastructure guidance: https://coder.com/docs/install/plan/sizing

  3. Create a workspace

    Follow the README quickstart to create a Docker template and provision a workspace. For devcontainer-based environments, consult the Docker, Kubernetes, and OpenShift guidance: https://coder.com/docs/user-guides/devcontainers

License & notes

AGPL-3.0The software is AGPL-3.0. Self-hosting requires operator-provided infrastructure and compute; production guidance calls for PostgreSQL 13 or later and an external access URL. AI model and API usage may incur separate charges. Coder Premium includes paid features. No prices are quoted here. If you modify Coder and let people interact with that version over a network, AGPL-3.0 requires offering those users the modified source; users can include internal users. Conveying modified copies has separate source and license obligations.

  • Operators supply and maintain the infrastructure and compute; production guidance calls for PostgreSQL 13 or later and an external access URL.
  • Model and API charges depend on the selected provider; the README does not provide prices.
  • AGPL-3.0 requires offering source to users interacting over a network with a modified version, including internal users. Conveying modified copies has separate obligations.
  • Coder has paid Premium features; supplied evidence does not specify which features require a paid edition.
