Your data updates in the browser as it changes, with server functions in TypeScript. Convex is a backend where the database, server functions written in TypeScript and live updates to clients come in one product. The pricing page lists a Free plan at $0 a month, with Starter as pay as you go past the free limits. Included each month are 1 million function calls, 0.5 GB of database storage, 1 GB of file storage and 1 GB of egress, plus auth, crons, text search, vector search and preview deployments. Professional is $25 per developer a month with 25 million function calls and 50 GB of database storage. Reddit developers describe it as strong for real-time sync, and one Hacker News commenter said shipping functions on the backend fixed what bothered them about Firebase. I found no usable G2 or Capterra reviews for this Convex.

👍 Good boy
+The Free plan includes the reactive database, file storage, text search, vector search, crons, auth and Node.js actions.
+The pricing page lists 1 million function calls, 0.5 GB of database storage and 1 GB of file storage included each month on Free.
+Starter is pay as you go past the free limits, with listed overage rates such as $2.20 per additional million function calls.
+Professional at $25 per developer a month raises the included amounts to 25 million function calls, 50 GB of database storage and 100 GB of file storage.
+A r/nextjs commenter said Convex seems great for real-time sync, while Supabase offers a more traditional Postgres database with row-level security and edge functions.
+A r/vibecoding commenter said Convex is very good if you need real-time and that the choice depends on what you build.
+A 2022 Hacker News commenter said many things sucked about Firebase, including its bespoke security rules and lack of views, and that shipping functions on the backend was on the money.
👎 Watch out
−The Free plan is capped at 1 GB of egress and 0.5 GB of database storage, which a growing app will cross, and Starter bills past those limits.
−Free allows 1 to 6 developers, 40 deployments and 16 concurrent queries, and daily backups, log streaming and custom domains start on Professional.
−Professional is priced per developer, $25 each a month, so the bill grows with team size as well as usage.
−Enterprise has a $2,500 monthly minimum, and SAML SSO, service SLAs and custom roles are listed only there.
−A r/reactnative commenter called Convex's own comparison page with other backends sketchy at best and disputed a claim about Supabase.
−A r/nextjs thread frames the choice as real-time sync on one side and a traditional Postgres database on the other, so Convex is not a drop-in for SQL-heavy work.
The catch
The pricing page shows a Free plan at $0 a month and says Starter is pay as you go beyond the free tier limits. Usage past the included amounts is billed at the listed rates, so check that a billing method is attached to the account before you run production traffic.
Included each month on Free and Starter: 1 million function calls ($2.20 per additional million), 20 GB-hours of action compute ($0.33 per additional GB-hour), 0.5 GB of database storage ($0.22 per additional GB), 1 GB of file storage ($0.033 per additional GB), 0.5 GB of search storage, 1 GB of database I/O and 1 GB of egress ($0.132 per additional GB). Query and mutation compute is free. Professional raises the included amounts, and the page says included amounts are shared across regions.
Daily backups, log streaming, exception reporting, custom domains and email support are on Professional and above. SAML and SSO, service SLAs and dedicated deployments are on Business and Enterprise, which start at a $2,500 monthly minimum.
Review-site evidence: my search for Convex on Capterra returned a different product with the same name (a sales intelligence tool), so I did not use it. The opinions here come from Reddit and Hacker News.
