The honest call
Which one should you pick?
There is no winner for everyone. Here is where PrimDB fits and where Heroku is the better choice.
When PrimDB fits
- You want Postgres, Redis, search, storage, and auth built in, not assembled from separate add-ons.
- You want approval-gated previews with a stakeholder feedback overlay, not just review apps.
- You want a native MCP endpoint so agents can deploy and read data over one API.
- You want one predictable bill for the whole stack, hosted in the EU.
When Heroku fits
- You want the most battle-tested PaaS, with years of production hardening and a massive add-on ecosystem.
- You rely on specific Heroku add-ons or buildpacks that PrimDB does not offer.
- You want a proven, widely documented platform. PrimDB is in early access.
FAQ
PrimDB vs Heroku, answered
- How is PrimDB different from Heroku?
- On Heroku you assemble Postgres, Redis, storage, and auth from separate add-ons. PrimDB bundles managed Postgres, Redis, search, S3 storage, and auth into one platform, adds a native MCP endpoint for agents, and offers approval-gated previews with a feedback overlay.
- Is PrimDB as mature as Heroku?
- No. Heroku has years of production hardening and one of the largest add-on ecosystems anywhere. PrimDB is in early access. If maturity and a broad add-on marketplace are decisive, Heroku fits better.
- Does PrimDB use buildpacks like Heroku?
- PrimDB builds and deploys straight from a Git repo. It does not market Heroku-style buildpacks, so if you depend on specific buildpacks, check the PrimDB docs before switching.
