Self-hosted, Pusher-compatible WebSockets server with a stalled maintenance record

The short version
- Each has a real cost: FastAPI no built-in ORM, requires separate database libraries; Soketi maintenance has effectively stalled: the maintainer has said time is severely limited, releases are infrequent, and the community has been discussing whether the project is abandoned, which means security fixes may not arrive.
- Prices and features above were last checked on 31 August 2026.
Where they differ
Only the attributes on which FastAPI and Soketi actually diverge.
Identical on both: starting price (Free), free tier (Yes), user rating (Not yet rated).

What people use each for
The jobs each tool is most often brought in to do.
FastAPI
- Building production-ready REST APIs with automatic validationnot Soketi
- Serving machine learning model predictions as REST servicesnot Soketi
- Building crisis management and orchestration platformsnot Soketi
- Enabling real-time APIs with WebSocket connectionsnot Soketi
- Rapid API development reducing boilerplate code significantlynot Soketi
Soketi
- A Laravel application that already uses Echo and wants to stop paying a hosted realtime providernot FastAPI
- Realtime notifications or presence indicators where data must not leave your own infrastructure for compliance reasonsnot FastAPI
- A local or CI environment that needs a Pusher-compatible server without hitting a paid accountnot FastAPI
- A high-connection-count application where hosted per-connection pricing has become the largest line in the infrastructure billnot FastAPI
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
FastAPI
- No built-in ORM, requires separate database libraries
- Python-only, cannot build with other languages
- Async/await learning curve for developers new to async programming
- Production deployment requires separate ASGI server configuration
Soketi
- Maintenance has effectively stalled: the maintainer has said time is severely limited, releases are infrequent, and the community has been discussing whether the project is abandoned, which means security fixes may not arrive.
- Dependency drift on Node and uWebSockets.js will eventually force you to fork or migrate, and that cost is unbudgeted at the point you adopt it.
- There is no commercial support to buy, so a production incident at three in the morning is entirely your problem with no escalation path.
- Scaling beyond a single node needs Redis and careful configuration, and getting presence channels correct across nodes is a genuine source of subtle bugs.
- It implements the Pusher protocol rather than tracking it, so any protocol feature Pusher adds later will not appear, and the compatibility guarantee slowly decays.

Questions people ask
- Is FastAPI or Soketi better?
- Neither clearly leads. FastAPI starts at Free and Soketi at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, FastAPI or Soketi?
- FastAPI starts at Free and Soketi at Free.
- Does FastAPI or Soketi run on more platforms?
- FastAPI runs on Web. Soketi runs on Linux, macOS, Windows.
- Can I use FastAPI for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is FastAPI best used for?
- FastAPI is most often used for building production-ready rest apis with automatic validation, serving machine learning model predictions as rest services, building crisis management and orchestration platforms, enabling real-time apis with websocket connections. Of those, building production-ready rest apis with automatic validation and serving machine learning model predictions as rest services are not what Soketi is typically brought in for.
- What can FastAPI do that Soketi cannot?
- Soketi covers Pusher protocol compatibility, Presence and private channels, Horizontal scaling, App management backends.
Answered from the vendors’ own pages
FastAPI: Is FastAPI free to use?
Yes. FastAPI is free and open-source under the MIT License. It costs nothing to download, use, or deploy in production. An optional paid service, FastAPI Cloud, offers one-command deployment for additional convenience, but the core framework is free.
SourceSoketi: Is Soketi still maintained?
Barely. The maintainer has stated that available time is very limited and releases have been sparse; treat it as community-maintained.
FastAPI: Can I use FastAPI for commercial applications?
Yes. FastAPI's MIT License permits unrestricted commercial use, modification, and distribution. You can build and sell products powered by FastAPI without licensing fees or restrictions.
SourceSoketi: Do I need to change my client code?
No. Pusher client SDKs and Laravel Echo work by changing the host, port and credentials.
FastAPI: Does FastAPI include a database or ORM?
No. FastAPI does not include a built-in database or ORM. You must add separate libraries like SQLAlchemy for database access. This gives flexibility to choose the database solution best suited to your project.
SourceSoketi: What does it cost?
Nothing in licence fees. It is MIT licensed; you pay for the server it runs on.
FastAPI: What Python versions does FastAPI support?
FastAPI supports Python 3.7 and later. Older Python versions are not compatible, so you must run at least Python 3.7 to use FastAPI.
SourceSoketi: What are people moving to?
Laravel Reverb for Laravel applications, and Sockudo, a Rust reimplementation, for others.
