Stackness opened on 15 August 2026: a social platform where people share, discover and discuss the tools and workflows they use to build software. It is for anyone in IT with opinions about their setup, from backend engineers and designers to DevOps specialists, PMs and vibe coders.
Developers answer "what do you use?" constantly, in blog posts, Twitter threads, /uses pages and dotfiles repos. Stackness turns that question into a product.
What can you do on Stackness?
Build your stack, share your moves, and see what everyone else is running.
Your stack on the record. Build a profile out of the tools you use, grouped into subspaces you name and arrange, and annotated with your own notes, config links, and screenshots. Every tool gets a start date and an optional end date, so your profile carries history, not just a snapshot. One link that answers "so what do you work with?" for good.
Show your moves. Tools are what you installed. Moves are how you work: the techniques, the setups, the workflow tricks. "I put an
instructions.mdin every project root before writing any code." "TDD-first for every feature, then let the AI implement." Write them in markdown with code blocks and images, tie them to the tools they touch, and put them where people will see them.Your Stackness is chronological. Backdate your history, retire a tool, add the one that replaced it. Other people can follow the whole arc of how your setup got here.
See what everyone else is using. Explore surfaces trending tools, trending moves, and rising stars. Follow the people whose taste you trust and keep an eye on the rest.
Watch tools rise and fall. Trend waves charts how popularity shifts over time, with rising and falling panels, category filters, and ranges from 90 days to all time.
Bookmark what you want to try. Save anything you spot in someone else's stack as want to try, trying or tried, and copy it into your own stack in one click.
Built for agents too. Stackness ships a hosted MCP server with 35 tools across stack management, profile layout, moves, feed, social and the tool database. Nothing to install or self-host: point your MCP client at
https://stackness.dev/api/v1/mcpwith an API key, as the MCP docs show, and Claude can read and manage your stack directly. A full REST API sits behind it too, with every public endpoint in the API reference.
What does Stackness cost?
Stackness is free for everyone. Supporters help keep it running and get the weekly trends newsletter, Trend waves, subscribers-only stacks and moves, a supporter badge and early access to new features.
What comes next?
This is the first version, and plenty of it is unfinished. The changelogs on this blog track what changes, and the RSS feed has each one as it ships.
Editor's note, 5 October 2026: this post first went out with the launch feature list. Collections and the to-try list have since become subspaces and Bookmarks, and the counts and perks above are current.
