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 is open source (MIT) and Render is not (Proprietary (hosted service)) — so the real question is whether you want to own the platform as a service stack or rent it.
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.
Side by side

Weighing both against staying on Heroku? Is Heroku free? What it actually costs →
Dokku
Strengths
- +Over a decade of stability; genuinely mature
- +Heroku buildpack support means many apps deploy unchanged
- +MIT and very light — runs on a small VPS
- +Extremely well documented for command-line use
Trade-offs
- −No web interface at all
- −Single-server by design
- −Assumes comfort with the command line
- −Fewer batteries included than Coolify
Render
Strengths
- +A real free tier — the thing Heroku removed in 2022
- +Fixed, predictable pricing rather than usage-based
- +Managed Postgres and Redis included
- +Straightforward migration path from Heroku
Trade-offs
- −Proprietary and hosted
- −Free tier services sleep when idle
- −Fewer regions than the hyperscalers
- −Less flexible than Railway for unusual setups
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose Dokku
if you want the source and the option to fork it, and you would rather run it on your own hardware, and your data should stay on machines you control.
Choose Render
if a real free tier — the thing Heroku removed in 2022.
Neither, yet
if both carry a real cost you should weigh first — no web interface at all, and proprietary and hosted. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
What it takes to run these yourself
Real requirements and honest running costs, not the vendor quickstart.
Dokku vs Render — common questions
Is Dokku a better fit than Render for platform as a service?
It depends on what you are optimising for, and the honest split is this: Dokku scores 95 to Render's 33 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Render earns its place on a different axis — a real free tier — the thing Heroku removed in 2022. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
Dokku keeps its data local or in open formats, so leaving is an export rather than a negotiation. Render keeps your data on its own infrastructure, which is the part to plan for: confirm the export path before you commit, not when you are already trying to leave.
Can I self-host Dokku?
Dokku can be self-hosted; Render cannot, so it stays on the vendor's infrastructure whatever you do.
Are Dokku and Render both alternatives to Heroku?
Yes — both appear in our Heroku comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Heroku and now choosing between the two replacements, which is a narrower and much easier question.
