GitApp.si gives every developer their own corner of the internet. Claim yourname.gitapp.si, build custom dev tools, and ship them — no servers, no DevOps, no waiting.
Try: alex.gitapp.si or myteam.gitapp.si
Two things that actually matter: your own subdomain, and the ability to build whatever tools you want on it.
Pick a name. Get yourname.gitapp.si — live instantly with free SSL. Save your tools, settings, and work — all tied to your personal subdomain you can share anywhere.
Not stuck with what we made. Build a JSON formatter, a markdown editor, a webhook tester — whatever you need. Push to your subdomain with one command, share it, done.
From zero to deployed in under a minute. No credit card, no waiting, no nonsense.
Email + password. That's it. No credit card, no "verify your phone".
Pick a name like alex — get alex.gitapp.si live in seconds.
Use a starter tool or write your own. Push with the CLI or via web editor.
One command deploys. Share the link. Done. Updates push in seconds too.
Made these myself. Use them as-is on your subdomain, or fork them and make your own version.
Paste, format, validate. Minify or beautify.
Encode and decode. Text, files, URL-safe.
Live match testing. JS, Python, Go flavors.
Crop, resize, convert. WebP, AVIF, PNG.
It's a platform I built because I wanted it to exist. The idea: every developer should be able to spin up their own corner of the internet — a subdomain, a place to run tools, a place to share things — without dealing with servers, DNS, certificates, or any of that stuff.
So I made GitApp.si. You sign up, pick a name, and you get yourname.gitapp.si. Then you can use the tools I built, or write your own, or fork someone else's, or all three. Your subdomain, your stuff, your rules.
I kept running into the same problem. I'd find a useful online tool — JSON formatter, regex tester, whatever — and want to save my work, come back to it later, maybe share it with a coworker. But every tool wanted an account, or it didn't save state, or it disappeared after a week.
So I thought: what if I just owned the URL? What if alex.gitapp.si/json was mine, and I could bookmark it, and my recent JSON was always there when I came back? That's the entire pitch. It's selfish, basically. I built it for me.
The best dev tool is the one that lives at a URL you can actually remember.
Sign up, pick a subdomain name, and you're in. Your subdomain lives at yourname.gitapp.si. After that, you can use any of the pre-built tools (they're all on your subdomain too), or build your own using the CLI:
# install the CLI $ npm install -g gitapp # login and claim your subdomain $ gitapp login $ gitapp init --subdomain alex # build a tool (any HTML/JS/Python file) $ mkdir my-tool && cd my-tool $ echo '<h1>hi</h1>' > index.html $ gitapp deploy → live at alex.gitapp.si/my-tool
That's it. No Dockerfile. No nginx config. No "wait 24 hours for DNS to propagate". The CLI handles build, deploy, SSL, everything. You just write code.
Frontend is plain HTML/CSS/JS — no framework needed for a static site, and the load time stays under 200ms. Backend runs on a small fleet of VPS instances with a simple Go API in front. Tools you build run in isolated containers with CPU and memory limits so one heavy tool doesn't take down everyone else.
For storage I use Postgres for user data and S3-compatible object storage for any files you upload. CDN in front of the static stuff for speed. The whole thing is open source — the platform, the CLI, the pre-built tools. MIT licensed, so fork away.
Right now I'm working on: real-time collaboration on tools (so you and a friend can edit the same regex pattern at the same time), a marketplace where you can publish tools for others to use, and team subdomains (so myteam.gitapp.si has shared tools for the whole crew).
I also want to add support for scheduled tasks. So you could write a tool that runs every hour, hits some API, and saves the result to your subdomain. Cron-as-a-service basically, but tied to your tools.
Found a bug? Open an issue on GitHub. Have an idea? Same place, or hit me up on Discord. I read everything and respond to most things — usually within a day, sometimes within an hour if I'm awake.
If you want to follow along with what I'm building, I post updates on Twitter and write a devlog on the blog. No email list though — I know those are annoying.
Yes — 100% free to claim a subdomain and use all the starter tools. You can upgrade later if you need more storage or custom domains.
No. You can use any of the pre-built tools without signing up. Sign up only when you want to save your work or build your own tools.
Currently GitApp.si provides yourname.gitapp.si subdomains. Custom domain mapping is on the roadmap — coming soon.
Anything that runs in a browser or a small container. HTML/JS/Python/Go tools, static sites, APIs, scheduled tasks. If it fits in a Docker container, it works.
Free. Takes 30 seconds. No credit card. You can always upgrade later if you need more.
