Supabase Free Postgres development platform: database, Auth, Storage, Realtime and Edge Functions. The Free plan is $0: unlimited API requests, 50,000 monthly active users, a 500 MB database on a shared CPU with 500 MB RAM, 5 GB egress plus 5 GB cached egress, 1 GB file storage, 500,000 Edge Function invocations, and Realtime with 200 concurrent connections and 2 million messages a month. Free projects are paused after 1 week of inactivity, with a limit of 2 active projects. Pro starts at $25 a month for the first project and includes $10 a month of compute credits, enough for one Micro instance.
  • Supabase makes daily backups only for Pro, Team and Enterprise projects, so a free project has none, and Supabase recommends exporting it yourself with the CLI's db dump command. (From supabase.com/docs/guides/platform/backups, read 2026-10-05.)
  • A paused project can be restored from the dashboard for 1 year. After that, only its backup file and Storage objects can be downloaded. (From supabase.com/docs/guides/platform/upgrading, read 2026-10-05.)
  • Supabase notifies you when you exceed the Free Plan quota. Continued overuse brings restrictions that can include a read-only database, 402 responses to every API request, or paused projects. They lift when the quota refills next billing cycle or on upgrade to Pro. (From supabase.com/docs/guides/platform/billing-faq, read 2026-10-05.)
  • Supabase's Free Plan needs no credit card; paid plans require one on file. (From supabase.com/docs/guides/platform/get-set-up-for-billing, read 2026-10-22.)

Neon Free Serverless Postgres with branching — free tier includes 100 CU-hours/month per project, 1 GB of Postgres storage per project (20 GB total across all projects), 5 GB of public network transfer per project per month, up to 100 projects, 10 branches per project, Neon Auth (60K MAU), auto-scaling up to 2 CU, scale-to-zero, 5 GB of Object Storage, and Functions (10 active capacity-hours, 400 waiting capacity-hours, 1M invocations). No credit card is required. The AI Gateway (one Neon credential for models from OpenAI, Anthropic, Google and others) is available on every plan, including Free. It requires a card and a $5 minimum purchase of prepaid credits in the Neon Console. The Free plan otherwise remains unchanged. Model prices match each provider's list price with no markup.
  • Neon's Free plan needs no credit card. (From neon.com/pricing, read 2026-10-22.)
  • An agent can create a Neon Postgres project without a Neon account. Unclaimed projects expire in 72 hours and are limited to 100 MB storage and 1 GB transfer. A person claims the project to keep it. (From neon.com/docs/reference/claimable-neon, read 2026-10-22.)
  • On the Free plan, scale to zero can't be disabled: computes suspend after 5 minutes of inactivity. (From neon.com/docs/introduction/plans, read 2026-10-04.)
  • Neon doesn't pause Free projects for inactivity: an idle database starts again on the next query, with no restore step. (From neon.com/pricing, read 2026-11-01.)
  • Running out of CU-hours or network transfer suspends the compute until the next billing period or an upgrade. (From neon.com/docs/introduction/plans, read 2026-10-04.)
  • Neon's Free plan provides 100 CU-hours per project per month. One CU allocates about 4 GB of RAM, and 100 CU-hours is enough to run a 0.25 CU compute (about 1 GB of RAM) for 400 hours, about 17 days of continuous running. All computes in a project count toward usage, including those for each branch and any read replicas. (From neon.com/docs/introduction/plans, read 2026-11-03.)
  • At the storage cap, inserts, updates and deletes fail until space is freed or the plan is upgraded. (From neon.com/docs/introduction/plans, read 2026-10-04.)
  • Neon's Azure East US 2, West US 3, and Germany West Central regions no longer accept new projects as of April 7, 2026; Free-plan projects there inactive for 90+ days may be deleted after October 5, 2026. (From neon.com/docs/import/azure-regions-deprecation, read 2026-10-07.)
  • Platforms that create databases for their users can apply for the Agent Plan. You must have a Neon Scale plan with a credit card on file and get Neon's approval. Neon sponsors the databases for your free-tier users. Paid usage gets up to $25,000 in credits and compute at $0.106 per compute-unit hour. (From neon.com/docs/introduction/agent-plan.md, read 2026-10-11.)
  • Neon gives $20 in free credits to try paid features, claimed through a promo link in the Neon Console. (From neon.com/pricing.md, read 2026-10-11.)
  • Neon's pricing page offers startups up to $100k in credits. The startup page describes the Databricks Startup Program, up to $200K in credits for Neon and Databricks for qualifying startups. (From neon.com/startups, read 2026-10-11.)
  • Neon's open source programme: Neon reviews each application and decides per project whether to support it with a monthly cash sponsorship through GitHub Sponsors, Neon credits, or both, and how much. Cash sponsorships come from a pool of at least $200,000 a year and run for six-month terms that do not renew automatically. Supported projects can receive up to $5,000 in Neon credits and up to $5,000 in Neon AI Gateway credits. It requires an OSI-approved license and a GitHub Sponsors profile. (From neon.com/programs/open-source.md, read 2026-10-29.)
  • After the free plan, Neon's paid plans bill only for usage, with no monthly minimum: Launch charges $0.106 per CU-hour of compute and Scale $0.222, both charge $0.35 per GB-month of storage, extra branches cost $1.50 per branch-month, and network transfer beyond 500 GB per project costs $0.10 per GB. (From neon.com/pricing.md, read 2026-10-15.)
  • Neon Realtime has been in public beta since 2026-10-15. It provides live updates from SQL queries without polling and is free during the beta. Compute and egress are billed under the plan; beta runs in four AWS regions: us-east-1, us-east-2, eu-central-1 and ap-southeast-1. (From neon.com/docs/realtime/overview, read 2026-10-16.)
  • Neon archives branches older than 14 days and not accessed for 24 hours. Unarchiving happens automatically when a branch is connected to or queried. Branches with large amounts of data may connect and query slower while unarchiving. (From neon.com/docs/guides/branch-archiving, read 2026-10-29.)

  • Turso's free plan needs no credit card. (From turso.tech/pricing, read 2026-10-22.)
  • The Developer plan costs $5.99 per month, or $4.99 per month when billed yearly. It includes 9GB storage, 2.5 billion rows read, 25 million rows written and 10GB syncs per month. Overage rates are $0.75 per GB storage, $1 per billion rows read, $1 per million rows written and $0.35 per GB syncs. (From turso.tech/pricing.md, read 2026-10-29.)
  • Overage billing on a paid plan is off by default. Enabling it lets you go over your plan's included limits and pay per usage. (From turso.tech/pricing.md, read 2026-10-29.)
  • On the Free plan, or on a paid plan with Overages off, your databases are blocked once you exceed the limit on any single metric. (From turso.tech/pricing, read 2026-10-29.)
  • Databases on the free plan are archived after 10 days of inactivity. The CLI command turso group unarchive <group-name> unarchives them. (From docs.turso.tech/cli/group/unarchive, read 2026-10-29.)

  • Adding the first payment method moves every free resource on the account to its paid plan: all Redis databases, plus QStash, Vector, Search and Blob. An account with a payment method cannot have free databases. (From upstash.com/docs/redis/overall/billing, read 2026-10-29.)
  • Paid databases do not get the Free plan's data and command allowance. (From upstash.com/pricing/redis, read 2026-10-29.)
  • Pay as You Go costs $0.20 per 100K commands. Storage past each database's first 1 GB is $0.25 per GB. Bandwidth past 200 GB a month is $0.03 per GB. (From upstash.com/pricing/redis, read 2026-10-29.)
  • A Pay as You Go database can have a monthly budget. When the budget is reached the database is rate-limited rather than continuing to bill. Budgets are set per database; there is no account-wide budget. (From upstash.com/docs/redis/overall/billing, read 2026-10-29.)
  • A free Upstash Redis database returns "ReplyError: ERR max requests limit exceeded" once it passes the monthly command limit. (From upstash.com/docs/redis/troubleshooting/max_requests_limit, read 2026-10-29.)
  • An agent can create an Upstash Redis database with no signup, card or API key by a POST request to upstash.com/start-redis. It is deleted after 3 days unless a person claims it from the console link in the response. (From upstash.com/pricing, read 2026-10-22.)

Frequently Asked Questions

What is the best free databases service?

We hold 45 Databases services in our catalogue, listed in the table above with each one's tier, published terms and the read and catalogue dates we hold. 41 of them state a free tier we hold as current and 4 do not — the tier column says which. Our ranking rule is published at /criteria.
How many free databases tools are there?
We track 45 databases services on AgentDeals, 41 of which state a free tier we hold as current. These range from generous always-free tiers to limited trial periods. Of the 45 Databases entries we hold, 29 carry terms a read confirmed in the last 90 days.
How stable are databases free tiers?
35 pricing changes have been recorded across databases vendors. Check our Stability Dashboard for per-vendor details.
