Slim – local domains and HTTPS for dev servers
Zero-config local HTTPS with auto-trusted certs beats manual mkcert commands, but problem already well-solved.

GUI config for web servers when Caddy and Nginx Proxy Manager already do this.
Small business owners, developers deploying simple web services
Caddy · Nginx Proxy Manager · OpenLiteSpeed WebAdmin
Zero-config local HTTPS with auto-trusted certs beats manual mkcert commands, but problem already well-solved.
DNS TXT records as redirect config means no separate control panel to manage.
Auto-HTTPS + DNS for .test domains, but mkcert and Caddy already solve this.
Native SwiftUI app with a tidy card-based UI and an anonymous, device-tied model — no account required — which is a smart privacy-first choice for a monitoring utility. The backend on Cloudflare Workers keeps the footprint minimal and the one‑time Pro unlock for unlimited domains + webhooks/API is pragmatic, but lack of a web dashboard or multi-device sync limits it to solo operators for now.
Worktree-aware domain conflicts solve the 'which branch am I testing?' problem.
Instant DNS/SSL/uptime checks plus an API, webhooks and reusable check templates make this a handy tool to fold into CI and lightweight automation. It's not reinventing monitoring — think UptimeRobot/Pingdom-lite — but being free, API-first and run on the author's infra gives it practical appeal for teams that want quick programmatic checks and Telegram alerts. To become a standout it needs multi-region probes, richer alert routing/SLO exports and clearer scaling/retention guarantees.
