[ + ] ANOTHER MANYROWS PRODUCT

Meet ManyRows Pier.
A typed home for your data.

Group types to share a common spine of fields, give each type any shape it needs, then drive it from a fast grid or a REST API. Export a spec for your own AI and import data in minutes — hosted, sortable, searchable. Inheritance by composition, not rigid categories.

FIELD INHERITANCE BYO-AI IMPORT REST API EARLY ACCESS

ManyRows Pier data grid — records with filter, sort, fields, and import/export

[01]

Identity is core infrastructure. Treat it that way.

Sessions, recovery emails, audit trail — some of the most sensitive data you hold. ManyRows keeps it in plain Postgres you can query, back up, and build on.

[02]

Predictable costs at any scale.

The software is free at any scale — self-host it and your only bill is the hardware it runs on. A signup spike never turns into a surprise invoice.

[03]

If you can't read it, you can't trust it.

Open source. Plain SQL migrations. Documented data model. Audit it, patch it, fork it.

One command.
Then it's yours.

One repo, one compose file, one Postgres. The binary embeds its own admin UI; schema, migrations, secrets, and the first admin user all bootstrap themselves.

terminal

# set MANYROWS_FROM_EMAIL in .env, then:
docker compose up -d
# → localhost:8080 · first registrant = super-admin
