Tidylnk

Sun, 23 Aug 2026 00:00:00 +0000

Tidylnk is a URL shortener I built to have a simple, self-hosted alternative to the usual third-party link shorteners, with an admin panel to manage and track links.

Tech stack

Backend — Go, serving the redirect and link-management APIs.
Frontend — a React admin panel for creating, organizing, and tracking shortened links.
Storage — PostgreSQL as the primary datastore for link records, with Redis on the redirect hot path for fast lookups.
Deployment — backend and database containerized with Docker and deployed on Railway.

Why I built it

I wanted a link shortener I fully controlled — no reliance on a third party’s uptime, rate limits, or analytics restrictions — and a project to exercise Go and Redis together on a workload where caching genuinely matters: redirect latency.

The TTS Study Assistant lets you select text on any webpage, save it as a note, hear it read aloud, and summarize it with AI for review. It’s a Chrome extension (Manifest V3), a Go/Fiber backend, and a React admin panel.

Architecture

Backend (Go) — Fiber for HTTP, PostgreSQL via GORM, JWT auth, OpenAI for summarization, deployed on Railway in a Docker container.
Frontend (React + TypeScript) — Vite build, React Query + Context for state, deployed on Vercel.
Extension — Manifest V3 service worker, Chrome Storage API for local state, Chrome TTS API for playback, content scripts for text selection.

Decisions worth noting

Source-based token lifetimes

Web sessions and extension sessions have very different UX expectations, so the access-token lifetime depends on where the request comes from:
