Best Free Database in 2026
Free plans can differ sharply: some are time-limited trials, while others offer ongoing usage or open-source self-hosting. This draft groups Database whose catalog pricing labels indicate a free tier or open-source option. Those labels do not guarantee current limits, card requirements, commercial-use rights, or long-term availability. Confirm each provider's current pricing page and licence before committing a workflow.

What to Look For
Permanent free tier, not a trial
The free plan must work indefinitely. No 14-day countdowns, no "free for the first month," no credit card required to start. If the only free option is a trial, the tool doesn't make this list.
Limits you can actually live with
Compare record, document, project, seat, and monthly usage limits against the volume your personal or small-team workflow actually needs.
You own your exports
Check whether the free plan permits standard-format exports before committing data. Export rights and paywalls have not yet been retained for every candidate.
No surprise downgrades
Free tiers can shrink or disappear. Check the provider's current pricing terms and keep an export path so a future plan change does not trap your data.
