Autosana (@autosanaai) is the end-to-end validation harness to close the loop with your coding agents, across iOS, Android, and web apps.

Engineering teams using Autosana have cut QA time by over 80%, caught huge bugs, and increased shipping velocity.

Congrats on the launch, @yuvansundrani and @jsteinberg54132!

Highly recommend @ExaAILabs if you want to give web search to your agents. I recently made a Reddit agent that does market research using Exa, and it's way more useful than regular chat web search.

[Hassen @hassen_dev]

Not to mention, it can spawn its own subagents, and can choose which underlying model it's running.

[Hassen @hassen_dev]

This unlocks so much, you can connect your favorite MCPs and tools and access the agent on the go.

solid year

[Hassen @hassen_dev]

Built an accountability tool that lets me set a goal and a deadline, and if I miss, it will automatically send money (USDC) to either a burn address or an anti-charity.

I built this for myself to help practice spatial navigation by pointing back to where you started after walking away.
This is my first app published on the App Store.

Found my grandpa’s old photos on Thanksgiving… so I built this.

[Hassen @hassen_dev]

It runs on Next.js with Firebase for auth, Firestore, Storage and Stripe for credits.
Most of the heavy lifting came from repurposing the pipeline I built for another project earlier this year.

WOW! Gemini 3 Pro 1 shotted this landing page.

@anything looks really sick, how did you make the video?

[Hassen @hassen_dev]

@weswinder I like the speed just wish it stored state / logins

I've been telling Cursor Agent to call `codex exec <code review prompt>` after large refactors, then looping the agent on the recommendations.
