Coolify alternatives (2026)

Coolify: Self-hosted PaaS that is actually usable.

Its Catch: Self-hosting means self-operating.

Below: 4 free or free-tier tools from the same category (self-hosted PaaS and deploy tools), free and open source first, then the closest match by shared tags. Each keeps its own Catch.

  1. 1.CapRoverFree PaaS you can run anywhere

    Free / OSS · Apache-2.0 · 15.2k GitHub stars

    VerdictSimple self-hosted PaaS for small deployments.

    CatchLicense: Apache-2.0 with an appendix that overrides it — no redistributing paid versions of CapRover, its paid features cannot be modified, and changes to the free features must stay free and open source. Read it before building on top. Documentation assumes Docker knowledge. Some advanced features require manual configuration. Less active development than alternatives.

  2. 2.WranglerMIT/Apache CLI for Cloudflare Workers; Free plan is real

    Free / OSS · Freemium · 4.6k GitHub stars

    VerdictWorkers CLI with a real Free plan. Free to develop; pay Cloudflare when traffic or CPU leaves the free envelope.

    CatchTied to Cloudflare’s platform: Free → Standard paid usage when you exceed quotas. Not a generic Node host and not Docker-on-VPS. Local emulation is good, production semantics still Cloudflare’s. Account + API token required to ship.

  3. 3.Fly.ioDeploy apps to VMs close to your users

    Free tier · Freemium

    VerdictFull VMs globally for developers who need more than serverless.

    CatchMore operational than PaaS alternatives. Pricing requires understanding. Some features are less polished. The free tier has limitations.

  4. 4.RailwayDeploy from GitHub with zero configuration

    Free tier · Freemium

    VerdictThe simplest path from code to production.

    CatchLess control than VMs or containers. Pricing scales with usage. Customization options are limited. Some workloads do not fit the model.
