gm legends, happy Thursday.
GitCity turns GitHub contributions into a city you can drive through, mngr is what happens when running a swarm of coding agents stops being fun and starts needing supervision, and Flowith Canvas is for the moment one AI chat turns into ten tabs in your brain.

Commit history got weird

<a href="https://www.producthunt.com/products/gitcity">GitCity</a> turns any GitHub profile into a little 3D city. Every commit becomes a building, consistency makes the skyline grow, and then, for some reason in the best way, you can switch into simulation mode and drive a car through the whole thing. It also comes with six visual themes, an embeddable README SVG, and no login nonsense. 
🔥 Our Take: This is so dumb in a very good way. GitHub has been giving us the same little green boxes forever. Turning your commits into a city you can actually drive through is way more fun, and honestly way more satisfying to look at.

GitHub but make it stupidly fun

<a href="https://www.producthunt.com/products/flowith/launches/flowith-canvas">Flowith Canvas</a> gives AI work a visual workspace instead of one long thread. You can drop prompts, notes, outputs, and references onto a canvas, branch things out, and keep the useful bits in view instead of buried in scrollback.
🔥 Our Take: You know that point where one chat stops being one chat. Now it is five ideas, three follow-ups, two things to compare, and one answer you cannot find anymore. This is for that.

Chat was the wrong shape for this

<a href="https://www.producthunt.com/products/imbue-7/launches/mngr-2">Mngr</a> is Imbue’s open-source command-line tool for running Claude, Codex, and other agent processes in parallel across local machines, Docker, Modal, or anything you can SSH into. It gives each run its own sandbox, lets you inspect transcripts and files, connect into stuck sessions, and aggregate the output without getting locked into one provider.
🔥 Our Take: The point is not just more agents. It is making parallel agent work inspectable. Spawning 100 Claudes sounds cool right up until some crash, some get stuck, and the rest hand you a pile of changes nobody wants to review. Transcripts, screenshots, file access, and a sane way to gather the results make this feel a lot more real.

Spin up hundreds of agents

Mahmudul wrote a refreshingly unpolished post about making $2,398 in 48 hours from Slashit, and the useful part is he does not pretend it was magic. It was 100 outreach messages, Reddit posts that pulled 25k+ views, Indie Hackers, asking users for reviews, fixing bugs on the fly, and barely sleeping. Good one if you want the less glamorous version of early traction, where the numbers are small, the work is very manual, and it still feels huge when strangers start paying.
