ReadMe, a company focused on building documentation sites, relies on several third-party tools to operate efficiently and avoid reinventing the wheel. Stripe is integral for handling consumer payments and has significantly influenced the seriousness of documentation, while Baremetrics provides essential analytics about customer behavior and financial metrics, including a new feature for managing failed payments. Intercom is crucial for user communication and relationship building, and Clearbit helps identify important user details, enhancing customer understanding. For search functionality, ReadMe transitioned from Mongo full text search to Elasticsearch, and is now migrating to Algolia for its speed and flexibility, despite its setup complexity. The company's blog, previously self-hosted, is now on WordPress to leverage its extensive tools and community, with Medium used for its ease of shared editing. These tools are fundamental to ReadMe's operations, underscoring the company's gratitude to the teams behind them.
