Convex review

Convex is a TypeScript backend platform that combines a database, backend functions, workflows, real-time sync, search and file storage. Instead of assembling separate services for those jobs, a team can build them within Convex’s platform. One Reddit user says Convex replaced several parts of their stack, including a database, ORM, API layer, authentication, storage and cache; that’s an individual account, not a guarantee that every project can drop the same tools.

The platform is built around reactive data: Convex says it keeps users up to date with the latest data, while providing ACID transactions for concurrent writes. Its workflows can checkpoint, retry and resume multi-step processes. Convex also includes tools for AI agents, including threads, context and vector search. The pitch is a more consolidated, TypeScript-centered backend, with real-time behavior built in rather than added as a separate service.

Convex’s clearest advantage is bundling backend pieces that often require separate services. Database, functions, workflows, sync, search and file storage are all part of the platform, and the functions use TypeScript. For teams already building in TypeScript, that can mean fewer backend components to configure and maintain. A Reddit commenter describes using Convex functions directly from React components with its hooks; that’s a user report, not a compatibility guarantee for every setup.

The built-in real-time sync is useful when an app needs clients to reflect current data without a separate sync layer. ACID transactions address concurrent writes, while workflows support checkpointing, retries and resuming multi-step jobs. Convex also has agent-focused features: built-in threads, context and vector search.

Pricing includes a free starting point, and the Professional plan bundles higher included limits with email support and daily backups. According to the pricing details, Professional includes 25 million function calls, 50 GB of database storage and 300 deployments. For teams whose usage stays within those limits, the per-developer price is straightforward to compare against a stack of separate services.

The limits matter, especially if a project grows beyond the free tier. Free & Starter includes 1 million function calls, 0.5 GB of database storage and 40 deployments. Professional raises those allowances to 25 million calls, 50 GB and 300 deployments, but costs $25 per developer per month. The pricing page lists overages too: on Professional, extra function calls cost $2 per million, database storage costs $0.20 per GB, and data egress costs $0.12 per GB.

Business & Enterprise starts at a $2,500 monthly minimum, with 50+ developers listed, so it is a substantial step up from Professional. It includes unlimited deployments, SAML/SSO, service-level agreements, dedicated deployments and volume pricing. Annual pricing and discount amounts are not published, making larger-team costs harder to compare in advance.

Convex’s all-in-one approach also means evaluating whether its bundled backend fits your project before replacing separate services. Reddit users disagree on the need: one praises consolidation, while another questions the benefit over a conventional stack. Those are opinions, not a measure of performance.

According to the pricing page, Free & Starter costs $0, with 1–6 developers, 40 deployments, 1 million function calls and 0.5 GB of database storage included. Starter is pay-as-you-go beyond those limits. That can work for a small project, but usage charges apply: for example, additional function calls cost $2.20 per million and database storage costs $0.22 per GB.

Professional is $25 per developer per month, with 1–20 developers, 300 deployments, 25 million function calls and 50 GB of database storage included. Overages are billed separately; additional function calls cost $2 per million, and database storage costs $0.20 per GB. The next listed tier is a sharp jump: Business & Enterprise has a $2,500 monthly minimum and is for teams with 50 or more developers. It includes unlimited deployments, SAML/SSO and service SLAs.

Annual prices and discounts are not published. Check expected calls, storage, I/O and egress against the included limits before budgeting; the per-developer fee is not the whole bill.

Treat a move to Convex as a backend migration, not a database swap. Its platform combines a TypeScript database, functions, workflows, real-time sync, search and file storage, so moving means accounting for each piece your app uses. The published product information does not describe a migration tool or data-export process. Confirm how you can export your data and rebuild dependent functions before committing; those details are not published here.

Moving away may take more work if your application relies on Convex-specific functions, workflows or real-time behavior. You would need to map those to the replacement backend and plan how clients receive updates. That is an architectural consideration, not a reported user experience. The published published material includes no Reddit posts, so we cannot reliably say what has made users leave or attribute migration complaints to Reddit. If predictable pricing or portability is a priority, clarify export options and model usage costs before switching.
