Hardening, firewall, logs, disk and monitoring for a single VPS.
Products

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. Working scripts, not just advice.

How to write a Go service you can leave running on one server: shutdown, timeouts, memory and systemd, with a working reference service behind every listing.
Postgres Point-in-Time Recovery Kit
Restore one PostgreSQL server to the moment before the bad DELETE, with scripts you can read in an evening and a drill that proves they work.
Go + systemd Zero-Downtime Deploy Kit
Release a Go service on one VPS without dropping requests, using only systemd, Caddy and bash. No pm2, no containers.
Go CLI Release Kit
Release a Go command-line tool the careful way: GoReleaser config, an installer that checks what it downloads, and the scripts around them.

Webhook idempotency and dedupe for SQLite and Postgres
Handle at-least-once webhook delivery safely: pick event ids, use unique constraints, size the dedupe window and make side effects run once.

Verify Standard Webhooks (Polar) signatures in Go
Write a dependency-free Go verifier for Standard Webhooks signatures as used by Polar, with secret rotation, replay protection and a known-answer test.
What's inside
- Deploys that don't drop requests. Blue/green behind Caddy served 20 requests per second with 0 failures; a plain restart failed 31 to 35 of roughly 115 to 120.
- Always a way back. Restore a backup, roll back a bad release, bring a database back to an exact point in time.
- Small enough to read. Every product is a set of scripts or a service you can read end to end, with its own test harness included.
Start with something free
A webhook signature checker and a restore-test script, both MIT licensed. Try the approach before you buy anything.
