CheatGrid

CheatGrid is a structured cheat sheet platform for developers, data professionals, and engineers. Every topic is organized in consistent 3-column tables (concept → example → description), ordered from most practical to most advanced — so you scan to the right answer in seconds instead of digging through articles or docs.

1300+ topics span programming languages, web development, cloud, AI, DevOps, databases, security, soft skills, and certifications. Every topic includes an interactive Mind Map to see the full concept landscape at a glance.

Practice tests with XP tracking and exam mode are available for most topics. Certification prep covers cloud, security, data & AI, and project management exams with structured study guides and domain-mapped practice tests.

Platform features include an AI chatbot for any topic in the library, My Vault for saving and organizing rows into custom reference tables, XP progress tracking, and advanced search across all topics.

Free cheat sheets are available without an account. Pro and Pro+ tiers unlock the full library, practice tests, certifications, and all platform features.
