The short version

  • Only Nixpacks has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; WorkOS authKit free tier limited to 1 million monthly active users; additional millions cost $2,500/month
  • 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.

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.

WorkOS

  • AuthKit free tier limited to 1 million monthly active users; additional millions cost $2,500/month
  • Per-connection pricing for SSO and Directory Sync ($125–$50 each) scales poorly for enterprises with many identity providers
  • Audit logs require separate subscription at $125/month per SIEM connection or $99/month per 1 million events
  • Radar fraud protection billed separately at $100/month per 50,000 additional checks beyond 1,000 free checks
  • Custom domain feature requires $99/month subscription
  • Requires annual commitment for SLA and support guarantees; pay-as-you-go tier lacks uptime guarantee

Questions people ask

Is Nixpacks or WorkOS better?
Neither clearly leads. Nixpacks starts at Free and WorkOS at $125/one-time per connection, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Nixpacks or WorkOS?

Can I use Nixpacks for free?
Yes. Nixpacks has a free tier, so you can try it without paying. WorkOS starts at $125/one-time per connection.
What is Nixpacks best used for?

Of those, understanding the build behaviour of a platform that adopted nixpacks before it was frozen and producing container images from a polyglot monorepo where nobody wants to own several dockerfiles are not what WorkOS is typically brought in for.

Answered from the vendors’ own pages

Nixpacks: 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.

WorkOS: How quickly can I implement WorkOS SSO?

Developers can implement single sign-on in minutes instead of months. Multiple customers report setting up SSO in less than a week, with WorkOS handling the complexity of SAML and OIDC protocols.

Source
Nixpacks: 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.

WorkOS: What SDKs does WorkOS provide?

WorkOS offers SDKs for Node.js, Python, Ruby, Go, PHP, Java, and .NET.

Source
Nixpacks: What replaces it?

Railpack, also from Railway and also MIT licensed, rebuilt as a BuildKit custom frontend for finer grained caching and parallel steps.

WorkOS: Does WorkOS support SCIM provisioning?

Yes. WorkOS supports SCIM provisioning integration with systems like Okta and Entra ID for automated user management.

Source
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.
