Our involvement with this open-source project is being sunsetted. Maintenance of this version will officially end after December 2025. This documentation website will remain available for the foreseeable future.
Why?
This decision marks a significant strategic shift for us. Over the past year, our team has completely rewritten the Aleph codebase from scratch to launch Aleph Pro. As we transition to this new supported platform, we are focusing our resources entirely on Aleph Pro to ensure we can keep the lights on for investigations around the world.For further details on this decision and what it means for the future, please read our official FAQs.
Timeline & Support
- We will continue to provide maintenance for this repository until December 31st, 2025. After this date, no further updates, bug fixes, or support will be provided by the core team.
