The short version
- Only Nixpacks has a free tier, so it costs nothing to try first.
- Each has a real cost: Microsoft Defender for Endpoint pricing not published on public websites; quote required from Microsoft sales; 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.
- They diverge on capability: Microsoft Defender for Endpoint covers Threat & vulnerability management, Nixpacks covers Automatic language detection.
- Prices and features above were last checked on 31 August 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Microsoft Defender for Endpoint
- Pricing not published on public websites; quote required from Microsoft sales
- Defender for Endpoint Plan 1 and Plan 2 do not include server licenses; additional licensing required for server protection
- Specific feature differences between Plan 1 and Plan 2 require consulting Microsoft documentation
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
Microsoft Defender for Endpoint: How is Microsoft Defender for Endpoint priced?
Defender for Endpoint is bundled into Microsoft 365 enterprise subscriptions. Plan 1 is included in Microsoft 365 E3, and Plan 2 is included in Microsoft 365 E5. Individual pricing is not published separately.
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.
Microsoft Defender for Endpoint: Does Microsoft Defender for Endpoint offer a trial?
Yes. A free trial is available for prospective customers to test the product before committing to a subscription.
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.
Microsoft Defender for Endpoint: What is the difference between Plan 1 and Plan 2?
Plan 1 (in E3) includes unified security tools, device controls, network protection, firewall, web/URL controls, APIs, SIEM connectors, and app controls. Plan 2 (in E5) adds endpoint detection and response, deception techniques, automatic attack disruption, exposure management, and threat intelligence.
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.
