Build system that turns a source directory into an OCI image, now in maintenance mode

The short version
- Each has a real cost: Cody sourcegraph now publishes a single Enterprise plan starting at $16K, with no free or individual Pro tier listed on the pricing page; Nixpacks the project is in maintenance mode with no commits on the default branch since May 2026 and no release since October 2025, so support for new language versions arrives only if someone forks it.
- Prices and features above were last checked on 31 August 2026.
Where they differ
Only the attributes on which Cody and Nixpacks actually diverge.
Identical on both: starting price (Free), free tier (Yes), user rating (Not yet rated), category (Developer Tools).

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Cody
- Sourcegraph now publishes a single Enterprise plan starting at $16K, with no free or individual Pro tier listed on the pricing page
- sourcegraph.com/cody redirects to the documentation rather than a Cody product or pricing page
- AI features are metered as credits included per user, and exceeding the allocation requires buying a higher volume bucket
- Volume credit buckets are sold as an add-on rather than included
- A customer success manager and premium support are optional paid extras on top of the Enterprise plan
- Standard support is 24x5 rather than 24x7, with round-the-clock coverage sold as an upgrade
- The published $16K figure is a starting price that scales with team size, so the actual cost is quoted rather than listed
Nixpacks
- The project is in maintenance mode with no commits on the default branch since May 2026 and no release since October 2025, so support for new language versions arrives only if someone forks it.
- Build determinism is softer than it appears, because providers pin a nixpkgs archive commit and bumping that archive silently moves compiler and runtime versions underneath a build that looks unchanged.
- Caching is limited to Docker layers rather than a content addressed graph, so a small change early in the build invalidates everything after it, which is exactly the limitation Railpack was rewritten to fix.
- Images carry Nix store layers and come out larger than an equivalent tuned Dockerfile or buildpack output, which costs registry storage and slows cold pulls on scale-out.
- There is no specification, no vendor neutral governance and no third party provider ecosystem, so a single company was able to redirect strategy and leave every downstream user with a frozen build tool.

Answered from the vendors’ own pages
Cody: Is Cody free?
Cody offers a free tier for individual developers via VS Code, JetBrains, Visual Studio, and the web app. Unlimited free usage is available for solo developers.
SourceNixpacks: Should I start a new project on Nixpacks?
No. The documentation and README both say it is in maintenance mode and recommend Railpack. Choose Railpack, Cloud Native Buildpacks or a Dockerfile instead.
Cody: What does Cody Enterprise cost?
Cody Enterprise pricing is custom and requires contacting Sourcegraph sales. It is available for Sourcegraph Enterprise customers and must be quoted based on your deployment and usage needs.
SourceNixpacks: Will my existing Nixpacks builds stop working?
Not immediately. Pinned nixpkgs archives keep resolving, so builds continue. What you lose is support for new runtime major versions and any fix for a provider bug.
Cody: What LLMs does Cody use?
Cody uses the latest large language models for code completions, chat, and debugging. It leverages Sourcegraph's advanced Search API to pull codebase context from local and remote repositories.
SourceNixpacks: What replaces it?
Railpack, also from Railway and also MIT licensed, rebuilt as a BuildKit custom frontend for finer grained caching and parallel steps.
Nixpacks: Is it still open source?
Yes, MIT, and the repository is not archived. Being open source does not help much when nobody is merging provider updates.
