Project mention: Show HN: Oxyde – Pydantic-native async ORM with a Rust core | news.ycombinator.com | 2026-03-13
This sounds great and there's a real gap in the ecosystem for a tool like this. https://sqlmodel.tiangolo.com/ looked promising but it's actually worse than useless because if you add it to your Pydantic models, it disables all validation: https://github.com/fastapi/sqlmodel/issues/52

Then in November, I got inspired from laramap and launched Indiemap for Indie-hackers & solo-founders. It was one map to gather all indie-hackers to connect with same builder same city from worldwide. Currently, I have 70+ indie-hackers there. I done build in public marketing for almost 2 months, then I took break due to family function and due to wedding season. I integrated payment gateway to monetize it with popular polar.sh for indie builders.

Project mention: Show HN: Next.js-like Python web framework, built for Htmx with FastAPI | news.ycombinator.com | 2025-10-01
Would be cool if it was opiniated with ready to use and interactive components like in FastUI (https://github.com/pydantic/FastUI)
If you do this, i'll use it. But maybe that's not the goal?
That’s how I like to use them framework to quickly bootstrap a project in Python only.
I've started working on a FastAPI with HTMX wrapper also 4 days ago, it's not as advanced as your projects tho. There's not much there yet, but here's the link: https://github.com/lakonguina/devanture

I remember reading The Twelve-Factor App [1] from the Heroku folks back in the day, and was blown away by how well they understood the problem. Not only that but they had great taste.
I moved things to Render a while back, and then to my own Hetzner server (I built kind of an open source Vercel clone for that reason [2]).
I'm not quite sure any of these platforms are going to be relevant 5 years from now when you can summon your own DevOps AI agent. At the very least it's going to be incredibly difficult to justify the premium on top of AWS.

mcp-context-forge
An AI Gateway, registry, and proxy that sits in front of any MCP, A2A, or REST/gRPC APIs, exposing a unified endpoint with centralized discovery, guardrails and management. Optimizes Agent & Tool calling, and supports plugins.
Project mention: Every AI toolchain is inventing its own safety layer. We shipped one that works across all of them. | dev.to | 2026-05-12Anthropic shipped Claude Code hooks — PreToolUse, PostToolUse, Notification, and friends. They run as subprocesses, get JSON on stdin, and decide whether the tool call proceeds. OpenAI ships tool guardrails in the Agents SDK — Python (and now TS) callables you attach to a tool, with tripwire booleans that abort the run. The MCP ecosystem is sprouting gateways and proxies for the same purpose: MCPX, IBM ContextForge, Microsoft's MCP Gateway, Lasso Security's MCP Gateway — all reasonable answers to the same wire-level question.
