Fusile

Fusile is a web asset precompiling file system proxy using FUSE to mount a virtual directory that compiles files on demand. Current stable version is v2.0.0, which switched from Babel 5 to Babel 6 (requires babel-core). It auto-loads installed transpilers (e.g., babel-core, coffee-script, less, node-sass, stylus) and compiles assets when accessed, with intelligent caching and optional file watching. Unlike build tools or module bundlers, it provides a proxy filesystem that serves compiled files transparently to any consumer (browser, server, linter). Maintained by Munter, now in maintenance mode.
