Show HN: I built a social media management tool in 3 weeks with Claude and Codex

I built something very, very similar for a client to post their content on schedule to about 9 different social networks. It was my first major vibe-coded app -- I normally vibe-code a function or small apps. Took about two hours with Claude [0] by just building up the functionality in layers, testing each layer as we went. If I'd rawdogged it, 2022-style, it would probably have taken me a month to write.

It's been running flawlessly for months without a single error. In fact, spooky good. I still feel nervous about it, though and check it every morning.

It is built mostly as a web app in .NET 10 Razor with SQLite db.

The APIs for the social networks are the hazy bit. As OP mentions, some are badly documented. Some are a pain to get access to. I was using a driven browser to post to Twitter, but they opened their API recently, which was nice.

[0] I used Claude in Github Copilot, so total cost was less than the $10/month in credits.

Recently I built a "azure devops deployment central" tool just because microsoft is unable to make their ui usable at scale.

The tool shows all pipelines, builds, buildagents and approval ready in one place at a glance. For the most actions I use the public api but approval I use the internal api because they are still not public, since 4 years.

The tool runs so smooth it scares me too! My guess is that the apis are so stable that it will work for the next 10 years.
