deck.gl is another open source rendering option with a TileLayer, TerrainLayer, and MVTLayer. Other libraries mentioned have better text label and styling support out of the box compared to deck, so typically people do interleaved WebGL rendering with deck.gl and other basemap libraries to get a beautiful base and a super performant deck overlay. Tile hosting is still typically a paid service from someone, though COGS and S3 are a self-hosting option. I primarily work on libraries adjacent to deck.gl, happy to answer questions.
