About SideGuide | Firecrawl | Mendable
SideGuide is a developer-first learning and tooling company building a tightly integrated ecosystem at the intersection of AI, documentation, and in-editor education. Initially launched as an in-VS Code learning assistant, SideGuide helps developers learn as they build, embedding live lessons and API walkthroughs directly into their coding environment. Its approach eliminates the friction of switching between documentation, video tutorials, and isolated environments—replacing that with contextual, hands-on guidance.
Read full description
From that foundation, SideGuide expanded its scope into backend tooling and AI-assisted developer infrastructure, launching Mendable and Firecrawl as core utilities in its ecosystem. Mendable is an AI-powered documentation assistant that integrates directly into developer portals or docs sites, enabling natural-language queries, example generation, and instant answers from complex technical repositories. It streamlines onboarding and reduces support costs by guiding developers to value faster.
Firecrawl, also developed by the SideGuide team, is a structured web scraping API tailored for use with large language models. It enables the extraction of clean, structured data from modern websites—static or dynamic—and prepares it for tasks like content summarization, code generation, or indexing for AI workflows.
Both Mendable and Firecrawl power Open Lovable, an open-source tool co-developed by the same team. Open Lovable allows developers to convert any website into a working React or Next.js app using AI, combining Firecrawl’s scraping capabilities with Mendable’s generation and embedding pipelines. It represents the practical culmination of SideGuide’s larger vision: making developers radically more productive by combining learning, automation, and code generation into a unified, open toolkit.
