Free 3D Tree and Plant Models
Foliage is the asset class where free libraries genuinely beat paid ones, mostly thanks to Poly Haven's scanned plants and Quaternius's stylised nature packs. The trade-off is polygon count: a scanned tree can carry more triangles than an entire browser scene should. Decide early whether you want scanned realism or low-poly stylisation, then stick with it, because the two never sit comfortably in the same shot.
Everything here is free to download from the source site. These results come from Quaternius, KayKit, Poly Haven, AmbientCG. Licences vary by file and are shown on each card. Nothing is hosted by us, and every link goes to the original page so you get the current version and the real licence terms.

Getting a free model into a browser game
Most of these download as GLB, glTF, FBX, or OBJ. GLB is the format the web wants, since it packs the mesh, materials, and textures into one binary file that three.js, Babylon.js, and PlayCanvas all load directly.
If your download is an FBX or OBJ, convert it to GLB in your browser. To see what's actually inside a file before you commit to it, open it in the GLB viewer, which shows the scene graph, materials, triangle count, and any animations. Before shipping, run it through the GLB optimizer to strip unused data and compress the geometry.
For characters, an unrigged mesh isn't a dead end. The auto rigger puts a skeleton on a humanoid model in a couple of minutes, and the animation library retargets 260 CC0 motions onto it without you opening Blender.
Licences, briefly
CC0 means public domain: use it commercially, modify it, ship it, no credit required. That covers everything from Kenney, Quaternius, KayKit, Poly Haven, and AmbientCG.
Freesound and OpenGameArt host a mix. Some files are CC0, others are CC-BY (credit required) or CC-BY-SA (credit required and derivatives must carry the same licence, which is a real constraint on a commercial game). The licence is set per file by whoever uploaded it, so check the source page before you ship.
The complete guide to game asset licences covers what each one actually requires and where teams usually get it wrong.
