Booleans and cleanup, 1,800+ CC0 materials on demand, HDRIs, cables, lighting, baking and batch rendering.
I build Blender add-ons. Around thirty of them so far — some free, some a couple of dollars, a few that took a year. Project LEUC is the one that is not a product: it is free update-check infrastructure, because every add-on developer was solving the same problem badly and separately.
Blender has no update mechanism for anything installed from a .zip. Drop an add-on in from disk and it lands in a local repository with no known origin, so Blender will never tell you a new version shipped. That is structural, not a bug.
The result is that a fix can ship on Monday and reach nobody. Every developer who cared about this wrote their own version-check endpoint, badly, on a server they forgot to renew. Project LEUC is that endpoint, done once, free, for everyone — no hosting, no fees, no lock-in.
It is free because infrastructure should be. It is not a business, and it does not need to become one.

Booleans and cleanup, 1,800+ CC0 materials on demand, HDRIs, cables, lighting, baking and batch rendering.
★ 5.0 (55) · was $22
Clean Panels plus delayed add-on loading — add-ons load in sets on demand instead of all at boot.
★ 5.0 (93) · was $18

All fifteen, including RanTools and Clean Panels Pro.
12 of them are pay-what-you-want, which means you can pay nothing and get the same file. They carry a small price on Superhive only because that store has no pay-what-you-want option.

Guides and roundups, mostly about getting more out of Blender without buying things you do not need.
Registered Blender add-ons receive redacted bug reports straight from a user's Blender session — tickets, dashboard triage, duplicate merging, and a Discord ping the moment one lands.
Project LEUC ·Most paid Blender add-ons can never notify you of a new version. The reason is structural, it affects the whole ecosystem, and it is fixable for free.
Project LEUC ·Why Blender startup slows to thirty seconds or more, how to measure which add-on is responsible, and the free and paid ways to fix it.

Roundups ·The best Blender add-ons for skies, clouds and atmosphere — True Sky, Physical Starlight, Cloudscapes — plus the free built-in sky to try first.
Roundups ·How to set up a Blender asset library that survives a real project — catalogues, metadata, link vs append — and whether to buy an asset manager.
Guides ·Value is not the same as cheap. A framework for judging what a Blender add-on is worth, plus the best return per dollar at every price.
Roundups ·Toon, clay, felt and hand-made looks in Blender — Komikaze, Clay Doh, Woolly and Surface Lab — plus the free NPR tools already built into Blender.
Roundups ·The best PBR material libraries for Blender, free and paid, plus how to build your own with the asset browser for nothing.
Guides ·The best HDRI add-ons and libraries for Blender, the free CC0 sources worth using first, and the world-shader setup that fixes most problems.
Guides ·RanTools is the best value, Hard Ops/BoxCutter the deepest, MESHmachine fixes what booleans break — and Bool Tool is free and already in your Blender.
Roundups ·The best Blender add-ons for cables, wires and pipes — Cablerator, GeoCables, GeoPipes — plus the free curve method that covers most jobs.
Guides ·The best Blender add-ons for rigging and animation — Auto-Rig Pro, Animation Layers, Faceit — plus the free tools, including two used in Blender's own films.
Roundups ·At under fifty dollars you can buy one category-leading Blender add-on or a whole toolkit. The best in each discipline, and what is just over budget.
Roundups ·Cheap Blender add-ons worth having — twelve are free on Gumroad, four cost under five dollars, and several more are already inside Blender.
Roundups ·The best Blender add-ons under $20, sorted by what you actually do — hard surface, UVs, environments, lighting, workflow. Prices, ratings and who made each one.
Roundups ·The best Blender add-ons between $5 and $10, mine and other creators, plus the free tools that make three common purchases unnecessary.
Roundups ·You know where you lose time now. The add-ons worth buying once you have a discipline, what to skip, and the collection problem starting to build behind you.
Roundups ·Almost everything a beginner needs is free and already in Blender, disabled. The tools to enable first, the three worth buying, and what not to buy yet.
Roundups ·The best Blender add-ons for hard surface, archviz, environments, texturing, UVs, character work and lighting — free options first, with honest limits.
Roundups ·At this level the tools are irreplaceable rather than convenient, and your add-on collection is its own maintenance problem. What is worth the money and why.
Roundups ·Bundles are usually the cheapest way to buy Blender add-ons and occasionally the most expensive mistake. The break-even rule that decides it.
Roundups ·A drop-in Python module that gives any Blender add-on update notifications in two lines. Zero config, free, and you keep hosting your own files.
Project LEUC ·Wire up an update check in about ten minutes and every install of your add-on learns about a new version on release day. Free, and it stays free.
