What people use each for
The jobs each tool is most often brought in to do.
Convex

- Agent backends that need durable state, scheduled work and transactional writes without assembling a queue, a database and a cachenot Webpack
- Small product teams who need a complete backend, including auth integration, file storage and subscriptions, without hiring infrastructure engineersnot Webpack
- Prototypes that must become production without a rewrite of the data layer, where end-to-end TypeScript types remove a class of integration bugsnot Webpack
Webpack
- Bundling modular JavaScript with automatic dependency resolutionnot Convex
- Processing multiple asset types into optimized production filesnot Convex
- Splitting code into vendor and application bundles for browser cachingnot Convex
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Convex
- The Functional Source Licence is not an OSI open source licence: competing use is prohibited until each release reaches its second anniversary and converts to Apache 2.0, so you may self-host but you may not build a service on it
- Transactions are bounded at one second of user code, 16 MiB read and written, 32,000 documents scanned and 16,000 written, so every backfill, migration or bulk import has to be chunked into scheduled batches rather than written as a single operation
- There is no SQL and no query planner; you declare up to 32 indexes per table and traverse them, and joins are loops in TypeScript, so an unanticipated access pattern requires a schema and index change rather than a new query
- It is not an analytical database, so reporting means streaming data out to a warehouse and BI tools cannot be pointed at Convex directly, which adds a pipeline the architecture diagram did not originally include
- The application is written against Convex's function and client APIs rather than a standard protocol, so leaving means rewriting the data access layer and replacing the reactivity model, not repointing a connection string
Webpack
- Complex configuration can be challenging for beginners compared to zero-config alternatives
- Build times slower than Go-based bundlers like esbuild, especially for large codebases
- Configuration fragmentation across many plugins increases maintenance burden

Questions people ask
- Is Convex or Webpack better?
- Neither clearly leads. Convex starts at Free and Webpack at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Convex or Webpack?
- Convex starts at Free and Webpack at Free.
- Does Convex or Webpack run on more platforms?
- Convex runs on Web. Webpack runs on API, Web.
- Can I use Convex for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Convex best used for?
- Convex is most often used for collaborative applications where several users see the same data and every client must reflect a change immediately, agent backends that need durable state, scheduled work and transactional writes without assembling a queue, a database and a cache, small product teams who need a complete backend, including auth integration, file storage and subscriptions, without hiring infrastructure engineers, prototypes that must become production without a rewrite of the data layer, where end-to-end typescript types remove a class of integration bugs. Of those, collaborative applications where several users see the same data and every client must reflect a change immediately and agent backends that need durable state, scheduled work and transactional writes without assembling a queue, a database and a cache are not what Webpack is typically brought in for.
- What can Convex do that Webpack cannot?
- Convex covers Reactive queries, TypeScript server functions, ACID transactions, Document database.
Answered from the vendors’ own pages
Convex: Is Convex open source?
It is source-available under FSL-1.1-Apache-2.0. You may read, modify and self-host it, but competing use is prohibited until each release converts to Apache 2.0 on its second anniversary.
Webpack: Is Webpack free?
Yes. Webpack is completely free and open source. It is maintained by the OpenJS Foundation and funded through sponsorships and donations.
SourceConvex: Can I self-host it?
Yes. The backend, dashboard and CLI can run on your own infrastructure, with most of the features of the cloud product. Self-hosted instances include a telemetry beacon that can be disabled.
Webpack: What can Webpack bundle?
Webpack can bundle JavaScript modules along with static assets including PNG, CSS, JPG, SASS, HBS files, and more, creating single or multiple chunks for browser usage.
SourceConvex: Does it support SQL?
No. Data is accessed through a TypeScript query builder over declared indexes. Relationships are traversed in code, which is explicit and type-safe but means no ad hoc querying.
Webpack: Does Webpack require configuration?
Webpack supports both zero-config and custom configuration approaches. For simple projects, no configuration is needed, but complex builds benefit from webpack.config.js customization.
SourceConvex: What happens if a mutation exceeds the limits?
It fails rather than running longer, so bulk work must be split into batches and scheduled. The limits are per transaction: one second of user code, 16 MiB read and written, 32,000 documents scanned and 16,000 written.
Webpack: What is the 2026 roadmap for Webpack?
Webpack's 2026 roadmap includes native CSS module support, universal target compilation for multiple environments, lazy barrel optimization, and advancement toward version 6.
SourceConvex: How does reactivity actually work?
Queries are deterministic functions and Convex records the data each one read. When a mutation changes that data, affected queries are re-run and subscribed clients receive the new result, so cache invalidation is handled by the platform.
Webpack: How does Webpack handle code splitting?
Webpack can create multiple chunks from a single entry point that are asynchronously loaded at runtime, reducing initial page load time by deferring non-critical code.
