Dev tooling has quietly become a rental market: monitoring, secrets managers, backups, status pages and snippet libraries all bill monthly. These 21 tools cover uptime, cron, SSL, logs, backups, licensing, link infrastructure and incident pages for a one-time price. Most are self-hosted — which for infrastructure tooling is the point, because your monitoring should not depend on another company’s uptime. Own the tool, own the alert.
10 of the 21 are available to buy today; the rest are marked “coming soon” and join the catalog — and the $997 bundle — as they ship.

How to choose
- Self-hosting is the default here — a $5 VPS runs most of these; weigh that one line item against the subscription you are cancelling.
- Prioritize the tools that page you: uptime, cron and certificate monitors earn their keep the first outage they catch.
- Most of these ship MIT source on GitHub, so you can audit the exact code that watches your infrastructure before you deploy it.
Frequently asked questions
What do I need to self-host these tools?
A small VPS (or a homelab box) and about ten minutes per app. Docker-based setups are the norm, and each product page documents the exact steps.
Is self-hosted monitoring reliable if my server goes down?
Run the monitor on separate infrastructure from what it watches — a $5 VPS in another region is the standard pattern, and it still costs less than one month of most monitoring subscriptions.
Are source-available dev tools safe to run in production?
Most ship MIT-licensed source you can audit before deploying — the opposite of a black-box agent. The secrets tools (Vaultly, Secretbox) encrypt at rest; details are on each product page.
What happens when a “coming soon” dev tool launches?
It flips to available on this site and joins the bundle automatically. Bundle owners get every catalog app, including future launches, at no extra cost.
