IT-Tools collection of handy developer and sysadmin utilities in one web app, with Docker Compose.
Last updated: Oct 2026
IT-Tools bundles dozens of small utilities into one fast web page: UUID and password generators, hash and HMAC tools, Base64/URL encoders, JWT parser, cron expression helper, subnet calculator, QR code generator, JSON/YAML converters and more. Everything runs in your browser.
Why you'd want it: All the little tools you normally search the web for, private and always one bookmark away.

No volumes.
No limits are set. This app is light, so add deploy.resources.limits only if you need to cap it.

docker compose logs -f.http://<SERVER_IP>:30007.Tip: create a small wrapper such as
alias dc='docker compose --env-file /opt/stacks/_shared/.env --env-file /opt/stacks/_shared/.secret'so every stack uses the same env files.
cd /opt/stacks/it-tools
docker compose --env-file ../_shared/.env --env-file ../_shared/.secret pull
docker compose --env-file ../_shared/.env --env-file ../_shared/.secret up -d
docker image prune -f
Back up /opt/appdata/it-tools before major upgrades. Watchtower can automate updates for stateless apps.
docker compose ps and docker compose logs --tail=100.:?err): run the config command above to see which variable is not set in your env files.Educational example. Review every path, port and credential before you deploy, and never publish your .secret file.
