Host your SaaS apps for less.
.NET, Java, PHP and Python, each in its own container. A free subdomain or your own domain, PostgreSQL, sign-in and security tools included.

Your code in a real container. The rest is done for you.
Bring a zip or a git repo. We build it, give it an address, a database and the safety rails.
Any language
.NET, Java, PHP, Python or a static site. One base image per language, kept patched.
A real container
Your own process, memory and disk. Not a shared PHP folder.
PostgreSQL + DB API
A database per app, a table editor in the browser and a ready REST API.
Subdomain or your own domain
your-app.systemi.in with HTTPS from the first deploy, or add your own domain.
Sign-in built in
Email and social sign-in for your users without writing it yourself.
Rate limits + firewall
Bot and abuse protection in front of every app, on by default.
Live in three steps
Sign up
Email or Google. No card, no trial clock.
Upload a zip or connect git
Pick the runtime, add env vars, tick "create a database".
You're live
At your-app.systemi.in. Push again to redeploy.
From the articles
What apps really use and how fast they start, measured.

Long requests behind a proxy: what happens to a 30, 60 and 120 second request in Python, PHP, Java and .NET, measured
Through default nginx a 120 s request is a 504 at 60 s on every runtime but one, 60 s succeeded 11 times in 24, and the work kept running for nobody after the error. Gunicorn kills sync workers at 30 s, PHP's limit counts CPU not waiting, and a PostgreSQL job table answers in 27.5 ms.

Point-in-time recovery for a small app database: WAL per day, archive size and restore time on PostgreSQL 18, measured
We simulated a day of writes on a 1 GB PostgreSQL 18 app database at 10, 100 and 1,000 writes a minute. Default settings made 226 MB, 1.64 GB and 12.1 GB of WAL a day, about 96% full-page images; zstd-compressed archive files cut that to 87.8 MB, 675 MB and 5.05 GB. A zstd base backup is 304 MB, a day replays in 1.3 s to 39.9 s, and archive_timeout = 60 with plain copies costs 24.2 GB a day.

What a redeploy costs your users: failed requests during a container restart for Python, PHP, Java and .NET, measured
At 100 requests a second, stopping the old container before starting the new one lost 32 to 212 requests per deploy, and the runtimes with graceful shutdown lost the most. Starting the new one first, switching nginx and waiting 1 s lost none. Plus what each runtime does with SIGTERM, Docker's 10 s trap and the settings that fix it.
