Hi HN! I built FreeTier.fyi to solve a problem I kept running into: spending considerable amount of time researching infra services that offer free tiers when starting new side projects.

What it does: - Compares free tiers across 50+ services (databases, hosting, AI APIs, monitoring, etc.) - AI-powered data pipeline that automatically extracts and updates limits from pricing pages - Smart search with category filters and side-by-side comparisons - Compare services directly with difference highlighting to see which offers better limits

What makes it different: - Always up-to-date: Unlike static lists, an AI pipeline scrapes pricing pages weekly and updates limits automatically - Nuanced extraction: AI can parse complex limits like "1M requests/month but max 100 req/sec" from messy pricing pages - Direct comparisons: Select multiple services and compare their free tiers side-by-side with clear highlighting of differences

The biggest pain point I found wasn't just knowing limits - it was discovering which services even exist. If you're new to AI development, how do you know about Groq, Cerebras, or OpenRouter? This is positioned as a discovery tool for developers getting into AI and modern development, helping them find the right free services without having to piece together scattered information.

Current coverage: Database (6), Hosting (7), AI Inference (9), Backend APIs (5), Monitoring (5), and more categories.

Would love feedback from the HN community! What services are you using for your side projects that should be included?
