VPS Deploy & Backup Kit
Ship a small app on one server with no failed requests, and back it up in a way you have actually restored.
Developer tools and guides
Run a small app on one server, and trust your backups
Scripts, a Go service and a handbook for shipping and recovering a small app on a single VPS. Each one is run in clean containers and ships with the numbers and the list of what was not tested.
Products
Go Webhook Receiver Starter
A small Go service that receives webhooks safely: verified, deduplicated, stored durably and retried, with your code in one function.
Small App on One VPS: Practical Handbook
Deploys you can undo, backups you have restored, and a recovery drill with a stopwatch. Tested scripts, not just advice.
What "tested" means here
- Measured, not claimed. The kit's zero-downtime deploys were load-tested at 20 requests per second through real Caddy: 0 failed requests in every blue/green run (about 210 requests each), against 31 to 35 failed of roughly 115 to 120 with the simple restart approach.
- Failures are tested too. Corrupt database, wrong repository, broken release, crash on start.
- Limits are listed. Every product page has a "not tested" section, in the same place a buyer looks for the price.
