The short version

  • Only Rowy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Rowy every Firestore limit is inherited, including the one megabyte per document ceiling and roughly one sustained write per second per document, which surprises users who expect spreadsheet behaviour.; Superblocks teams plan is limited to just 1 hosted app by default, with additional apps costing $10/app/month.
  • They diverge on capability: Rowy covers Firestore backed grid, Superblocks covers Clark AI agent.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Rowy

  • Every Firestore limit is inherited, including the one megabyte per document ceiling and roughly one sustained write per second per document, which surprises users who expect spreadsheet behaviour.
  • Firestore has no joins, so linking tables in the grid is a convenience layer rather than a relational feature and reports across collections still need a separate query.
  • It is useful only to teams already on Firebase, so choosing it effectively locks the operational tooling to one cloud vendor.
  • Query costs are billed by document read, and an unfiltered grid on a large collection can generate a bill that a spreadsheet user has no intuition for.
  • Development activity has slowed relative to the broader category, so evaluate current maintenance before making it load bearing for internal operations.

Superblocks

  • Teams plan is limited to just 1 hosted app by default, with additional apps costing $10/app/month.
  • Usage is capped by Governed Agent Units, adding a metering layer beyond a flat per-seat price.
  • Advanced deployment options like VPC and Cloud-Prem are reserved for the custom-priced Enterprise tier.
  • No published free tier, only a 14-day trial, making it harder to evaluate at no cost long-term.

Answered from the vendors’ own pages

Rowy: Where is my data stored?

In your own Firestore instance inside your own Google Cloud project. Rowy does not hold a copy.

Source
Rowy: What does it cost to run?

No licence fee. You pay Google Cloud for Firestore reads, writes, storage and function invocations, and an open grid on a big collection reads a lot.

Superblocks: Is there a free plan?

Superblocks does not offer a free ongoing plan but provides a free 14-day trial of the Teams plan.

Source
Rowy: Can it do joins across collections?

Not really. Firestore does not support joins, and no interface layer can add them.

Superblocks: Who owns the code Superblocks generates?

Superblocks states that users fully own all code generated on the platform and can connect it to their own git repository.

Source
Rowy: Is there a row limit?

Not from Rowy. The limits that bite are Firestore document size and per document write throughput.

Superblocks: What deployment options does Superblocks offer?

Superblocks supports Cloud, Hybrid (production data kept in the customer's VPC), and Cloud-Prem (the full platform run inside the customer's environment) deployment models.

Source
Rowy: Is it suitable if I am not on Firebase?

No. It is specifically a Firestore interface.
