What switching from Heroku costs

Heroku: current plans and prices are on Heroku's pricing page.

AlternativeHow you run itSoftware costWhat you pay for
CoolifyYour server, or the project's hosted plan$0 (Apache-2.0)A server you rent (or own), or the project's paid hosted plan.
DokkuYour server$0 (MIT)A server you rent or own, plus your time for updates and backups.
CapRoverYour server$0 (Mixed or custom, check terms)A server you rent or own, plus your time for updates and backups.

Self-hosting basics: Coolify, Dokku and CapRover need a server, which can be a small cloud server or a spare machine at home. For a sense of scale, DigitalOcean's price list shows a 1 GiB server at $6/month and 2 GiB at $12/month (checked Oct 29, 2026). Check each project's documented requirements before choosing a size, and budget time for updates and backups.

Don't want to run a server? Coolify offers a hosted plan run by the project itself. Prices change, so check each project's site.

License check: CapRover does not use a single standard open-source license that GitHub can detect. Read the license before using it in a business.

Heroku alternatives: common questions

What is the best open-source alternative to Heroku?

It depends on how you use Heroku. Of the 3 options here, Coolify is the most followed on GitHub (65.3k stars) and is actively maintained, with its latest release on Oct 28, 2026.

Is there a self-hosted Heroku alternative?

Yes. Coolify, Dokku and CapRover run on a server you control, so your data stays with you. If you'd rather not run a server, Coolify also offers a hosted plan from the people who make it.

Is there a free alternative to Heroku?

Yes. Every project on this page can be downloaded and used at no cost from its public repository. Server apps are free software, but you pay for the server they run on. Check the license of CapRover before using it in a business.

Are these Heroku alternatives still maintained?

As of Oct 29, 2026, 3 of 3 had a code push or release in the last 180 days. None are flagged as inactive or archived. We re-check every project weekly.

How much does it cost to switch from Heroku?

The software itself is free. For server apps, the main cost is hosting: as a reference point, DigitalOcean lists a 1 GiB server at $6/month and a 2 GiB server at $12/month (checked Oct 29, 2026). Check each project's documented requirements before choosing a size. The hidden cost is time: moving your data and, for self-hosted apps, keeping up with updates and backups.

Are all of these really open source?

Not all under a standard license. CapRover: GitHub could not identify a single standard license for this repository (often a mix of open-source and commercial parts). Read the LICENSE file before using it. The others use OSI-approved open-source licenses.
