Original: Build vs buy: what running your own CAPTCHA-solving stack actually costs
Short summary
A detailed cost analysis of building versus buying a CAPTCHA-solving stack, arguing that the fully-loaded cost of self-hosting is routinely underestimated. A real in-house stack requires challenge detection, browser fleets, proxy management, concurrency, retry logic, and ongoing monitoring against continuous anti-bot vendor changes. The maintenance treadmill alone often costs more than a solving subscription, making buy the default choice unless captcha solving is your core product or you have extreme volume.
- •Self-hosted CAPTCHA solving is a standing on-call commitment, not a one-time build — vendors ship changes continuously that silently break success rates
- •Fully-loaded in-house cost includes 1-3 engineer-months initial build, ongoing proxy and infra costs, and 0.2-0.5 FTE indefinite maintenance
- •Buy wins by default; build only makes sense if solving is your core product, you have unique requirements, or extreme volume justifies dedicated staffing
