The short version

  • Each has a real cost: FaunaDB the hosted service was wound down in 2025, so there is no managed Fauna to buy; every remaining user either operates a JVM cluster themselves or migrates, and both are projects rather than tasks.; Saleor saleor requires development resources to build a storefront, since it ships as an API-only backend without a front-end store out of the box.
  • They diverge on capability: FaunaDB covers Document-relational model, Saleor covers GraphQL API.
  • 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.

FaunaDB

  • The hosted service was wound down in 2025, so there is no managed Fauna to buy; every remaining user either operates a JVM cluster themselves or migrates, and both are projects rather than tasks.
  • The open-sourced repository has had no substantive activity since May 2025 and the drivers were frozen alongside it, so you inherit responsibility for security patches in a Scala distributed database that almost nobody else is running.
  • FQL has no wire or dialect compatibility with anything else, so migrating off is a rewrite of every query, index and access rule in the application rather than a data export.
  • No BI tool, ORM or CDC connector speaks FQL, so reporting and analytics always required exporting the data first, and that export tooling is now also unmaintained.
  • The community was small before the shutdown and has dispersed since, so operational answers, tuning advice and people who have run a Fauna cluster in anger are all scarce when something breaks.

Saleor

  • Saleor requires development resources to build a storefront, since it ships as an API-only backend without a front-end store out of the box.
  • Self-hosting requires managing infrastructure, scaling, and updates, which adds operational overhead compared to fully managed platforms.
  • Saleor Cloud's paid tiers start at $1,599/month, making the managed offering costly for small merchants compared to typical SaaS store builders.
  • The GraphQL-first, code-driven approach has a steeper learning curve for non-technical users than drag-and-drop e-commerce builders.

Answered from the vendors’ own pages

FaunaDB: Can I still sign up for Fauna as a service?

No. Fauna Inc. wound down the hosted service in 2025 and the company website is no longer serving. The only way to run Fauna now is to build and operate the open-sourced server yourself.

Saleor: Is Saleor free to use?

Yes. Saleor is open source under the BSD-3-Clause license and can be self-hosted for free. Saleor Cloud also offers a free Sandboxes tier for prototyping and development.

Source
FaunaDB: What licence is the open-sourced code under?

Apache 2.0, with the copyright held by a FaunaDB Foundation. That is a permissive OSI licence with no competing-use clause, so you may run it, modify it and even offer it as a service.

Saleor: How much does Saleor Cloud cost?

Saleor Cloud paid plans start at $1,599/month for the Select plan (up to $200,000 monthly GMV), with Volume at $3,999/month and custom Enterprise pricing for larger merchants.

Source
FaunaDB: Is the open source version the same software that ran the cloud?

It is the core database engine. The control plane, billing, dashboard and multi-tenant operational tooling that made it a service are not part of the release, so you are running the engine, not the product.

Saleor: Does Saleor provide a storefront out of the box?

No. Saleor is an API-only, headless commerce backend built on GraphQL; storefronts must be built separately using the API and are not bundled with the platform.

Source
FaunaDB: What should I migrate to?

There is no drop-in target. Teams that valued the document model with relationships usually land on Postgres with JSONB, and teams that valued the serverless HTTP access pattern usually land on DynamoDB or a managed Postgres with an HTTP driver. Either way the query layer is rewritten.

FaunaDB: How hard is it to self-host?

It builds as a fat JAR and runs as a multi-node JVM cluster. There is an OPERATING.md, but no supported packaging, no operator, no upstream releases and no support contract, so budget for a distributed-systems engineer, not a container.
