Beating FastAPI

Wed, 15 Jul 2026 00:00:00 +0000

One thing which Go does a lot better than Python is single binary deployments. As an experiment I thought, why not have a way to package up Go as part of a Python package, similar to maturin - and also have a way to spin up a Python webserver that is packaged as a Go binary.

The results were definitely interesting:

Go binary had 9x more throughput than stdlib Python’s http library, and ~5x more throughput than FastAPI
Idle memroy usage was `3x higher for FastAPI, and the peak memory usage was ~2x higher than Go binary

Of course the pocket python restriction may be too much for more complex applications.

A look at Campfire for self-hosted Slack alternative

A look at Campfire for self-hosted Slack alternative

March 2026

Campfire is not really a commonly suggested alternative to Slack/Discord. Afterall its missing various features including voice chat, threads or other features. It makes up for it by being incredibly easy to self-host and easy to write a bot that can interact in such an interface.

Campfire can be hosted from a single Dockerfile using sqlite as its database. For majority of low-numbered user-count situations this is more than sufficient.

Python MCP - Mounting to an Existing FastAPI ASGI Server

Python MCP - Mounting to an Existing FastAPI ASGI Server

April 2025

You can mount the SSE server to an existing FastAPI ASGI server dynamically. The way I’ve made it work is as follows:

 1sse = SseServerTransport(...)
 2
 3...
 4app.router.routes.append(Mount("/messages", app=sse.handle_post_message))
 5
 6@app.get("/sse")
 7async def handle_mcp_connection(request: Request):
 8 async with sse.connect(sse(request.scope, request.receive, request.send) as (
 9 read_stream,
10 write_stream,
11 ):
12 await mcp._mcp_server.run(
13 read_stream,
14 write_stream,
15 mcp._mcp_server.create_initialization_options(),
16 )

This seemed to work pretty well, along with having Redis as an intermediary broker for dealing with state.

Dependency Injection via SQLModels isn't worth it

Dependency Injection via SQLModels isn’t worth it

February 2025

It’s been something I’ve been mulling over for a while now. I’m not convinced using Session with Dependency Injection is worth it. The abstraction is nice, visually, but the lack of context makes things really hard to reason with, especially if you’re doing something beyond a simple getter/setter. This happens if you’re building an application that performs a flow or some business logic rather than a pure CRUD, then you may need to do multiple commits in a single query which may not need to all be rolled back. This of course breaks some kind of assumption to do with “a single unit of work”.

Python & TypeScript - in Review (2024)

Python & TypeScript - in Review (2024)

December 2024

One thing that I like to stress is the importance of tooling and relying on defaults. By being able to speak consistently within ones own projects or using commonly seen patterns reduces the mental overhead. These could be folder structures or idioms, especially things which permeate across different programming languages or frameworks.

Here are some of my thoughts on Python and TypeScript; coming from someone who is predominantly a Python developer and does minimal front-end work.
