STOP Paying BuiltWith, SimilarTech & Wappalyzer - Use THIS instead

Discover the zero-key, zero-limit API and browser extension powered entirely by our community-no paywalls, no personal data, just pure, real-time insights.

Introduction

Tired of paying thousands for basic website technology data? Meet Open Tech Explorer, the free, community-driven alternative to BuiltWith, SimilarTech, and Wappalyzer-built from scratch in just 48 hours. No subscriptions, no limitations, and absolutely no personal data collection.

The Paywall Problem

Traditional tools lock you behind expensive tiers:

• BuiltWith: $295–$995/year for limited to unlimited technologies and features.

• SimilarTech: $99–$225/month with caps on tables, keywords, and history.

• Wappalyzer: $250–$850+/month for basic to enterprise. These costs exclude small teams, indie developers, and researchers from vital insights.

Rapid MVP: 2 Days to Launch

Inspired by hackathon urgency and a vision for open data, I prototyped Open Tech Explorer over 2 days:

1. Day 1: Core extension UI & API endpoints.

2. Day 2: Community ingestion pipeline & privacy audit. By Friday evening, the Chrome extension was live, ready to crowdsource tech-stack data.
