Dokku vs Render
Both are alternatives to Heroku. Here's how they stack up — verified facts, no spin.
Also searched as Render vs Dokku — same comparison, one verdict.
Dokku
The original self-hosted PaaS — small, stable, unglamorous.
Dokku has been doing this since 2013 and describes itself accurately as the smallest PaaS implementation you have seen: Git-push deployment via Docker, Heroku buildpack support so existing apps often deploy unchanged, and a plugin system for databases and TLS. MIT, around 32k stars. It has no web interface — everything is the command line — and that is deliberate. For someone comfortable in a terminal it is the most dependable option here, and it has outlived several better-funded competitors.
Render
The predictable managed option, with a real free tier.
Render offers web services, static sites, cron jobs, managed Postgres and Redis at fixed, legible prices, with a free tier that genuinely works for small projects — the thing Heroku removed. It is deliberately less clever than Railway and more predictable as a result, which for a team that wants to know next month's bill is the more useful property. Proprietary and hosted. It is the straightforward commercial answer for anyone who left Heroku over price but does not want to become a system administrator.
