  • Studying a production implementation of deterministic distributed transactions, since the full server source is now readable under Apache 2.0not Coder
  • Forking the engine deliberately, where an organisation has JVM and distributed-systems staff and wants a document-relational store it fully controlsnot Coder

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Coder

  • Premium plan pricing is not published and requires contacting sales
  • Requires self-hosting and managing the underlying infrastructure, unlike fully managed cloud IDEs
  • High availability, audit logging, and RBAC are gated behind the paid Premium tier, so the free Community edition lacks enterprise controls

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

Can I use Coder for free?
Both have a free tier, so you can try either at no cost before committing.
What is Coder best used for?
Coder is most often used for running self-hosted development environments behind a corporate firewall, standardizing developer workspaces across a large engineering org, giving approved ai coding agents governed, isolated workspaces, enforcing sso and audit trails on developer environment access. Of those, running self-hosted development environments behind a corporate firewall and standardizing developer workspaces across a large engineering org are not what FaunaDB is typically brought in for.

Answered from the vendors’ own pages

Coder: Is there a free plan, and what are its limits?

Yes, the Community edition is free and includes unlimited workspaces, templates, and organization members with OpenID Connect SSO, aimed at hobbyists and small teams.

Source
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.

Coder: What does Premium add over Community?

Premium adds ticket-based SLA support, multi-organization access controls, resource quotas, audit logging, AI governance, workspace proxies, high availability, and custom branding.

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.

Coder: How is Coder priced?

Community is free; Premium is priced per user annually, with the exact rate available by contacting Coder.

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.

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.
