The short version

  • Each has a real cost: 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.; Nile limited to B2B SaaS use cases, not optimized for single-tenant applications
  • They diverge on capability: Convex covers Reactive queries, Nile covers Multi-tenant virtualization.
  • Prices and features above were last checked on 30 August 2026.

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.

Nile

  • Limited to B2B SaaS use cases, not optimized for single-tenant applications
  • Query token abstraction makes pricing less transparent than traditional compute pricing
  • Free plan limited to 50M query tokens and 1GB storage for development
  • Serverless startup latency may impact performance-sensitive applications
  • Per-million token overages require careful monitoring to avoid surprise costs

Questions people ask

Is Convex or Nile better?
Neither clearly leads. Convex starts at Free and Nile at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Convex or Nile?
Convex starts at Free and Nile at Free.
Does Convex or Nile run on more platforms?
Convex runs on Web. Nile runs on Web, API.
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 Nile is typically brought in for.
What can Convex do that Nile cannot?
Convex covers Reactive queries, TypeScript server functions, ACID transactions, Document database. Nile covers Multi-tenant virtualization, Serverless compute, Vector embeddings, Tenant branching.

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.

Nile: What are query tokens and how are they calculated?

Query tokens are abstract units of CPU and memory used when queries execute on Nile's serverless compute. The platform uses this abstraction to enable fair, predictable pay-per-use pricing.

Source
Convex: 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.

Nile: Do all Nile plans include multi-tenant isolation?

Yes. All plans including the free tier include unlimited databases, tenants, and vector embeddings with built-in data isolation.

Source
Convex: 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.

Nile: What is included in the Pro plan?

The Pro plan ($15/month) includes 150M query tokens, 5GB storage, 10,000 connections, and a 99.95% SLA. SAML and MFA authentication features are available on Pro and above.

Source
Convex: 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.

Convex: 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.
