Microlink

An open-source API turns headless browser capabilities into a simple, developer-friendly service offering endpoints for screenshots, metadata extraction, and PDF generation. Originally built as a side project by a solo developer who wanted to strip away the complexity of managing browser infrastructure, the product grew by staying focused on doing a few things exceptionally well rather than chasing feature bloat. The subscription-based SaaS now generates $18,000 per month, proving that a lean, utility-driven tool with clear documentation and reliable uptime can sustain meaningful revenue without venture funding or a large team.
