Sunsetting decomp.dev

decomp.dev, a platform launched in 2024 to centralize decompilation progress and foster a community of skilled individuals, has decided to shut down. Historically, decompilation of moderately-sized games required years of effort from a team of contributors. However, advancements in tooling and knowledge-sharing led to accelerated progress.

The integration of AI into decompilation began in early 2026, with models trained on the platform's tools. While AI could achieve decent results in clean codebases, it still required significant human intervention to correct obvious issues and cheating. More recent models, like GPT-6-Astra, have shown even greater proficiency in following complex instructions, cross-referencing resources, and generating coherent code.

The AI's ability to write scripts testing various source code forms has significantly improved the decompilation process. Despite these advancements, the community aspect of decompilation has deteriorated. Originally designed to gamify the experience, the platform inadvertently turned into a numbers game driven by token burners.

While genuine contributors emerged, the public index and leaderboard system has caused more harm than good. decomp.dev will continue to track existing projects and provide individual project pages and historical data, but the main index and adding new projects will be disabled. The repository remains under human-written code, and no replica can use decomp.dev's code in any form.

The author, a hobbyist, regrets not having the energy to define and enforce "good" decompilation standards across the numerous projects. The author wishes to thank everyone involved in the projects, communities, and tools, emphasizing that the people and passion behind them have always made them enjoyable.
