Developer Tools — pay-once tools

API docs, webhooks, cron monitoring, secrets and backup tooling — pay-once and self-hosted utilities for people who ship software.

Developers rent an absurd amount of plumbing by the month: webhook inspectors, cron monitors, screenshot APIs, secret stores. This category is pay-once and self-hosted tooling for people who ship software. Wrangle bundles ten everyday data utilities — JSON conversion, JWT decoding, diffs, regex, hashing — into one offline app. Hookscope captures, inspects and replays webhooks with URLs that never expire, while Snapfleet turns any URL into a PNG, JPG or PDF on your own server at zero cost per render. Pingcron alerts you when a scheduled job fails to check in, Certwatch watches TLS certificates with real handshake checks, and Linkguard crawls your site for broken links. Vaultkeeper runs encrypted database backups to S3, FTP or disk, Secretbox versions your environment secrets with a CLI, and Logbin collects and tails logs. Docsmith API publishes static API references, Snipvault manages snippets, Keymaster signs offline-verifiable license keys, Maptrail crawls for SEO, and Queuecraft runs waitlists. Buy once, deploy anywhere.
