// why this exists

Prices change weekly
AI tools restructure pricing every few months. We snapshot every plan daily so you can see the trend instead of last quarter's screenshot.
No fluff comparisons
Built by a builder, not a marketing team. The data is the product — not a 3000-word listicle wrapped around an affiliate link.
Solo-founder lens
We index the stack you actually use: newsletter, automation, agents, SEO, video. Not the enterprise sales catalog.

// what is buildersos.ai?

BuildersOS is an independent, daily-updated AI tool and SaaS pricing tracker built for solo founders, indie hackers, and small builder teams. We capture every plan from the official source page every day, store the historical trend, and publish documentation-based comparisons of the tools used in a solopreneur stack. Detected price changes are reviewed by a human before articles are updated; AI-assisted writing is labeled; affiliate links are disclosed. Use it before committing to an annual plan, when picking the right tier, or when comparing two tools head-to-head.
