Airtable is sold per editing seat. Free covers individuals and very small teams, Team is $20 per user a month billed annually and Business is $45 per user a month billed annually, with Enterprise Scale quoted. Users who can edit at least one base are charged, while read-only collaborators, form submissions and share links are free. In exchange, the platform provides the interface layer as well as the storage: records with linked fields, different views per team, interfaces built without code, automations, and AI agents that act across records on models from OpenAI, Gemini, Llama and Anthropic inside Airtable's AWS environment.
TL;DR
These are two answers to the same question, asked by different people. Airtable is a hosted database with a spreadsheet-like interface where non-technical teams build apps: Free covers small teams, Team is $20 per user a month billed annually and Business is $45, with read-only collaborators and form submissions free. Supabase is a Postgres platform for developers: Free gives 500 MB of database, 50,000 monthly active users and 5 GB of egress, Pro starts at $25 a month with the first project included and $10 of monthly compute credits, additional projects cost from $10 each, and Team is $599 a month. Airtable prices people; Supabase prices projects and usage. Choose Airtable when business users must maintain the data, and Supabase when developers must own the schema.
Supabase is sold per project and per unit of usage. Free includes 500 MB of database, 50,000 monthly active users, 5 GB of egress and 1 GB of file storage, with projects paused after a week of inactivity and a limit of two active projects. Pro starts at $25 a month with the first project included and additional projects from $10 each, and it includes 100,000 monthly active users, 8 GB of disk per project, 250 GB of egress, 250 GB of cached egress, 100 GB of file storage, 7-day backups and 7-day log retention; paid plans also include $10 a month in compute credits, enough for one Micro instance. Team is $599 a month and adds SOC 2 and ISO 27001, project-scoped and read-only access, SSO for the dashboard and priority support, while Enterprise is custom. Each project is a full Postgres database with authentication, row level security, edge functions, storage, realtime and vector search.
The audience is the dividing line. Airtable assumes the people who understand the process will maintain the data themselves, so it optimises for views, permissions and interfaces a business team can change without a deploy. Supabase assumes developers will write the schema, the policies and the API calls, so it optimises for Postgres compatibility, SQL, row level security and portable code. A non-technical operations team that needs a working internal tool this week gets further with Airtable at $20 a seat. A product team that needs a backend it owns, with queries it can index and data it can export, gets more per dollar from Supabase, where the entry price is $25 a month for the first project rather than $20 per person.
| Feature | Airtable | Supabase |
|---|---|---|
| Entry price | Team at $20 per user a month billed annually | Pro from $25 a month, first project included |
| Free tier | Free plan for individuals and very small teams | 500 MB database, 50,000 MAU, 5 GB egress, 1 GB files |
| How it scales | Per editing seat | Per project plus usage metres |
| Top tier | Enterprise Scale, custom pricing | Team at $599 a month, Enterprise custom |
| Interface layer | Views, no-code interfaces and forms included | None; developers build the front end |
| Underlying database | Proprietary records, not portable as a database | A full Postgres database per project |
| Auth and access | Admin roles, RBAC and IDP-synced groups on paid tiers | Built-in auth with row level security; project-scoped access on Team |
| Included users | Charged per editing seat; read-only collaborators free | 100,000 monthly active users on Pro, then $0.00325 each |
| Overage model | Usage capped at plan limits rather than billed | $0.125 per GB disk, $0.09 per GB egress, $0.00325 per MAU |
| Best fit | Operations teams maintaining their own internal tools | Product teams that need a backend they own |
Pick Airtable if
Airtable is the right database when the constraint is people, not infrastructure. Team at $20 per user a month billed annually, Business at $45 and a Free plan for very small teams mean an operations lead can model a process, build an interface and add automations without waiting for a developer. Read-only collaborators and form submissions do not consume seats, which keeps the bill tied to people who actually change data. The cost model is the risk: a 20-editor team pays $400 a month where Supabase's entry project is $25, and there is no portable Postgres to walk away with if you outgrow the product.
Pick Supabase if
Supabase wins on price per project and on ownership. Free is a real tier with 500 MB of database and 50,000 monthly active users, Pro is $25 a month with the first project included, $10 of compute credits and additional projects from $10 each, and Team at $599 a month covers SOC 2, ISO 27001 and dashboard SSO. Everything underneath is Postgres, so authentication with row level security, edge functions, storage, realtime and vector search all sit on a database you can query, index and export. The work sits with your team: there is no no-code interface layer, and usage beyond the included allowances is metered per GB and per monthly active user.
Neither vendor publishes third-party review data we are willing to restate as fact, and we did not run either product. Every figure here comes from the two vendors' own pricing and product pages as published when this comparison was written. The lists headed 'vendor-published claims' are the vendors' own statements, not user reviews.
Per team, Supabase is usually cheaper at the entry point. Pro starts at $25 a month with the first project included, while Airtable's Team plan is $20 per user a month billed annually, so even five editors costs $100 a month. Both have free tiers: Airtable's Free plan for individuals and very small teams, and Supabase's Free tier with 500 MB of database and 50,000 monthly active users.
Not directly. Airtable is a hosted record store with an interface layer rather than a portable database, so you cannot take the schema with you or run SQL against it the way you can with Supabase, where every project is a full Postgres database with row level security, edge functions and API access.
Airtable charges per editing seat, so growth in people is what raises the bill, and usage beyond a plan's record, automation or API limits is capped rather than billed as overage. Supabase charges per project plus usage metres: additional projects from $10 each, then $0.125 per GB of disk, $0.09 per GB of egress and $0.00325 per monthly active user beyond the 100,000 included on Pro.
Airtable includes AI as part of the platform, running models from OpenAI, Gemini, Llama and Anthropic inside its own AWS environment, with agents that act across records and admin controls for enabling them. Supabase is infrastructure: vector search and ML integrations let you store, index and search embeddings from providers such as OpenAI and Hugging Face, but the intelligence lives in your application rather than in the product.
Supabase Pro at $25 a month covers the first project, and the included $10 in compute credits is enough for one Micro instance; you pay extra only for additional projects from $10 each or for usage beyond the included 100,000 monthly active users, 8 GB disk and 250 GB egress. Airtable costs $20 per user a month billed annually on Team, so the same app with four editors runs $80 a month before any upgrade to Business at $45 per user.
