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.; Xlinesoft the purchase includes one year of support and upgrades only; after that, newer versions require a paid upgrade.
  • They diverge on capability: Nixpacks covers Automatic language detection, Xlinesoft covers Database to web application.
  • Prices and features above were last checked on 12 November 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.

Xlinesoft

  • The purchase includes one year of support and upgrades only; after that, newer versions require a paid upgrade.
  • Multiple database connections, REST API connections and single sign-on through Active Directory, Okta or SAML are Enterprise-only, which raises the price from $599 to $999 per developer.
  • Self-hosted only. Hosting, database administration, backups, runtime updates and access-control configuration remain the customer's job, as Xlinesoft's own product facts page states.
  • Applications built on Microsoft Access require a Windows web server.
  • PHPRunner and ASPRunner.NET are separate products with separate licences, so moving a project between PHP and .NET is not covered by one purchase.

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.

Xlinesoft: How much does PHPRunner cost?

PHPRunner Professional is $599, Enterprise Edition is $999 and MultiDev Edition, which includes three Enterprise licences, is $3,599. Professional and Enterprise prices are per developer, and each purchase includes one year of email support and free upgrades.

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.

Xlinesoft: Which databases does PHPRunner support?

MySQL, MariaDB, Microsoft SQL Server, PostgreSQL, Oracle, Microsoft Access, IBM DB2, Informix, SQLite and ODBC-compatible databases. Using multiple database connections in one project is an Enterprise Edition feature.

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.

Xlinesoft: Is there a free trial?

Yes. PHPRunner can be downloaded and evaluated for 21 days, and public live demos show the generated applications, with add, edit and delete disabled.

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.

Xlinesoft: Where do PHPRunner applications run?

On your own web server. The documented options are Apache and Microsoft IIS with a compatible PHP runtime and database extensions, and a built-in web server is available for local testing. The development application itself runs on Windows, macOS and Linux.

Source
Xlinesoft: What does the Enterprise Edition add?

Multiple database and REST API connections, data encryption, and enterprise authentication including Active Directory, Okta, Azure AD, OpenID and SAML, on top of all Professional features.

Source
Xlinesoft: What is ASPRunner.NET?

Xlinesoft's equivalent builder for ASP.NET. It generates database-driven ASP.NET web applications with the same kind of forms, reports, charts, permissions and Page Designer, and is sold separately from $599.
