What is Xalen Ephemeris?
Xalen is an open-source planetary engine in pure Rust, no unsafe in the core, under Apache-2.0. No C toolchain, no ephemeris data files, no AGPL. One engine covers 12+ traditions (Vedic, Western, Chinese, Lal Kitab, I-Ching, numerology) with 50 ayanamsa and 23 house systems. Validated against a 5,000,000-chart sweep, sub-arcsecond vs NASA JPL DE440. A drop-in Swiss Ephemeris alternative. Try it: pip install xalen. Rust, Node and WASM build from the repo.
