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

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
Octopus Deploy
- Free tier caps at 10 projects, 10 tenants, 10 machines, 10 users, 5 concurrent tasks and 1 space
- Annual billing is the only option for both Octopus Cloud and Octopus Server; there is no monthly plan
- Professional cloud tier is $4,330 per year and Enterprise cloud is $24,600 per year, with tenants and machines sold as add-ons beyond the free allotment

Which should you pick?
Choose Convex if
- You need reactive queries.
- You want to start without paying.
- You also want typescript server functions.
Questions people ask
- Is Convex or Octopus Deploy better?
- Neither clearly leads. Convex starts at Free and Octopus Deploy at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Convex or Octopus Deploy?
- Convex starts at Free and Octopus Deploy at Free.
- Does Convex or Octopus Deploy run on more platforms?
- Both run on Web, so platform support will not decide this one for you.
- 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 Octopus Deploy is typically brought in for.
- What can Convex do that Octopus Deploy 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.
Octopus Deploy: How much does Octopus Deploy cost?
Octopus Deploy offers a free tier at $0/year with limits on projects (10), users (10), and tenants (10). Professional plans start at $2,080/year for self-hosted or $4,330/year for cloud hosting.
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.
Octopus Deploy: What does the free Octopus Deploy tier include?
The free tier includes 10 projects, 10 tenants, 10 machines, 10 users, 5 concurrent tasks, 1TB file storage, 100GB database storage, and community support only.
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.
Octopus Deploy: Can I try Octopus Deploy for free before purchasing?
Yes, a free tier is available with unlimited duration but capped usage, plus a 30-day free trial with full Enterprise features is offered to evaluate the platform.
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.
Octopus Deploy: What are the Enterprise pricing differences between Cloud and Server hosting?
Enterprise Cloud hosting costs $24,600/year and includes 20 concurrent tasks and 24/7 support. Enterprise Server self-hosted costs $15,600/year with flexible concurrent task configuration and 24/7 support.
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.
