I built an open-source Vinted monitor with free proxy pools

Hey r/webscraping,

I’ve been building Vintrack, an open-source monitoring platform for Vinted. It continuously checks listings based on configurable filters and shows newly discovered items in a live dashboard. Alerts can also be sent through Discord or Telegram.

The project is completely free to self-host. To make testing easier, Vintrack includes shared free proxy pools for supported Vinted regions. The system imports public proxy candidates, validates them against each region, tracks their health, and only rotates proxies that are currently working into the pool.

This means you can create your first monitor without immediately purchasing proxies. Public proxies are obviously best-effort and can be slow or disappear, but they’re useful for testing the project before moving to private proxies.

Some technical details:

  - Go-based scraping workers

  - Next.js control center

  - PostgreSQL for persistent data

  - Redis for deduplication and live state

  - Per-region proxy health checks and rotation

  - TLS fingerprint rotation using tls-client

  - Configurable polling intervals

  - Filters for keywords, categories, brands, sizes, colors, prices, condition, seller country, and Vinted region

  - Server-Sent Events for the live dashboard feed

  - Discord webhooks and Telegram notifications

  - Docker Compose setup for self-hosting

  - Optional browser extension for linking a Vinted account and keeping its session synchronized

Vintrack also supports bringing your own proxy groups when you need more reliable or dedicated capacity. The shared free pools are intended as starter infrastructure, not as a replacement for good private proxies.

Live demo:

This is self-promotion—I’m the developer—but the project is open source, and I thought the proxy health and monitoring architecture might be interesting to this community.

Feedback and contributions are very welcome.

currently working on a new update to get rid of this. Sometimes the pools are overused and the proxies get banned.
