OSSTag – An Open-Source, Privacy-First Alternative to Google Tag Manager

Hi everyone :waving_hand:,

I’d like to share :contentReference[oaicite:0]{index=0}, an open-source project focused on building a privacy-first, developer-friendly tag manager.

OSSTag aims to be a modern alternative to traditional tag managers (like GTM), giving teams full control over their tracking and event pipelines without relying on opaque third-party scripts.


:magnifying_glass_tilted_left: What is OSSTag?

OSSTag is an open-source tag management system that lets you:

  • Collect and manage events without loading third-party trackers in the browser
  • Self-host and fully own your data
  • Avoid cookies, fingerprinting, and hidden scripts
  • Build analytics pipelines that are more transparent and privacy-respecting

:sparkles: Key Features

  • :white_check_mark: Fully open source (MIT licensed)
  • :locked_with_key: Privacy-first by design
  • :technologist: Developer-friendly (TypeScript, modern web stack)
  • :globe_with_meridians: Server-side and unblockable tracking
  • :building_construction: Designed for self-hosting and extensibility

:vs_button: Why OSSTag instead of traditional tag managers?

Traditional tag managers rely heavily on client-side scripts, third-party vendors, and browser cookies.
OSSTag takes a different approach by enabling server-side event collection and routing, making it:

  • More resilient to ad blockers
  • Easier to audit and customize
  • Better aligned with modern privacy expectations
