Choose the better self-hosted PaaS
ZenSailor competes directly with Coolify, Dokploy, and CapRover. They are open source; ZenSailor is not. If source access is mandatory, choose them. If you are an individual developer choosing the best daily deployment experience, compare the actual workflows and try ZenSailor free before deciding.
ZenSailor vs Coolify
Coolify is the most established open-source option in this category, with a large community and a bigger catalog of community-contributed services. Choose it when source access or community size decides the purchase. For an individual developer choosing on day-to-day product experience, ZenSailor is the stronger alternative: health-gated blue/green releases cover Compose workflows when the datastore supports concurrent revisions, while single-writer stores get a safe serialized cutover. Multi-node operation uses a purpose-built agent mesh, failure diagnosis is built in, and every stack in the catalog is version-pinned and checked before it ships. Both now provide native MCP access. The ZenSailor single-developer edition is free forever.

Dokploy is a capable open-source PaaS with Docker Compose, backups, previews, and Swarm clustering. Choose it when you want to inspect or modify the platform source. Choose ZenSailor when you want the more opinionated product: health-gated blue/green releases by default for concurrent datastores, safe serialized cutovers for single-writer stores, NATS-meshed agents instead of Swarm as the control model, a catalog where every stack is version-pinned and checked before it ships, built-in AI diagnosis, and native MCP control. Both are free for an individual self-hoster.

CapRover is the veteran here — it has been stable and dependable for years, it is open source, and it runs happily on very small servers. Where it shows its age is configuration: it uses its own captain-definition format rather than deploying your docker-compose.yml directly, and its UI predates the current generation of tooling. ZenSailor is a newer, heavier product that takes your Compose file as-is.
