Where each one falls short

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

curl

Open-source with no vendor pricing: curl is free and open-source under GPL 3.0; no subscription or licensing costs apply
Commercial support costs hidden: site references 'commercial support available' but pricing is not detailed or accessible from homepage
No SaaS model: curl is a command-line tool and library; costs are limited to optional commercial support contracts (pricing unknown)
Self-support burden: free software means customers rely on community forums or undisclosed commercial support pricing

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.

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

curl: Is commercial support available for curl?

Yes. The curl website references 'commercial support available,' but pricing and details are not disclosed on the homepage and require visiting the support page.

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.

curl: Can I sponsor curl financially?

Yes. The curl website offers an option to 'Sponsor curl financially.' Visitors can donate to support curl development, but the donation link must be accessed through the site's support section.

Source

Rowy: Can it do joins across collections?

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

Rowy: Is there a row limit?

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

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

No. It is specifically a Firestore interface.
