The problem
Every small project started the same way: you pay ScreenshotOne for screenshots, PDFShift for PDFs, Hunter.io for email validation, Wappalyzer for tech detection, and some DNS API nobody remembers the name of — a dozen vendors, a dozen bills, a dozen dashboards to watch.
The "right" tool for each job was never the problem. Paying five subscriptions, managing five keys, and reading five docs just to ship a side project — that was the problem.
The product
ToolCenter is that single key. 40+ REST endpoints — screenshots, PDFs, SEO, DNS, WHOIS, SSL, web scraping, metadata, 20-odd smaller utilities — all metered against one shared quota. Plus an MCP server exposing 15 of those tools to AI agents (Claude Desktop, Cursor, Claude Code).
Fair pricing: €0 for hobby projects (100 calls/month, no credit card), €9 for production apps (10,000 calls), €29 for teams (50,000). No seats, no tiers, no addons. One number.
Why trust a solo operator
Running a SaaS alone means predictable — I can't pivot into an enterprise pivot, can't get acquired by a conglomerate, can't lay off the team. The product evolves at a human pace. If something breaks, the same person who wrote it answers the email.
Infrastructure is deliberately boring: Laravel + Puppeteer + SearXNG on dedicated servers. No fragile SaaS chain. If any external dependency dies tomorrow, ToolCenter keeps running.
What you're buying
Mostly time. Time you don't spend wiring five APIs. Time you don't spend managing keys. Time you don't spend writing retry logic. You pay €9/month so those hours go into building your product instead.
