About Project LEUC

Our Mission

Project LEUC exists to solve a simple but persistent problem: version fragmentation in Blender add-ons. We provide a centralized, free, and reliable platform for developers to notify users about updates.

We believe that update checking should be a commodity, not something each developer has to build from scratch. By standardizing this functionality, we help developers focus on what matters most - building great add-ons.

Why We're Free

Project LEUC is free because we believe infrastructure for the Blender community should be accessible to everyone. Whether you're building your first add-on or maintaining a portfolio of commercial tools, you should have access to the same update checking capabilities.

We keep costs low by leveraging edge computing and smart caching. The service costs us very little to run, so we pass those savings on to you.

Technical Philosophy

• blender_manifest.toml is the source of truth - We read from the official manifest, not legacy metadata or module names.
• Batched, not chatty - One call to the bulk endpoint resolves every add-on you have installed, instead of each add-on opening its own connection on startup.
• Static manifests on a CDN - Published version data is mirrored to object storage and served as plain files, so a routine check never has to touch the database.
• Comparison you don't have to write - The API can do the version comparison for you, so no add-on has to reimplement semantic version parsing and get the edge cases wrong.
• Off is a real option - Update checking can be disabled entirely, and the anonymous install ID can be deleted from one file. See the Privacy Policy.
