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.

The concept, example, description table format is a smart constraint. Do you write the 1300+ topics by hand or generate a draft and then review each one? Curious how you keep quality even across that many.

Thanks! The 1,700+ sheets are drafted by agentic pipelines we built, checked by code and evaluated with LLM judges, and we spot-check them by hand (I'm the founder, a software, data and AI engineer with 10+ years in the field, so a lot of it is my own stack). Each content type (cheat sheets, flashcards, practice tests, checklists and the rest) has its own pipeline with a few hundred rules. It first does deep research across official docs, PDFs and other sources, then drafts with Claude models (currently Opus 5.5), for cheat sheets always inside that concept / example / description format. The judges score dozens of criteria, with correctness and no hallucinations at the top, and we tuned the pipelines against those scores over many rounds. Updates work the same way, re-researching the latest docs and primary sources. It's not perfect yet and we keep improving it, so if you spot a wrong row, tell us and it gets fixed.
