Constellations is a high-performance, real-time, battle-tested, closed-source Cosmos indexer written in Rust by Fabien Penso.
It’s commercially available upon request—please get in touch for details.
Currently in use by Stargaze, it handles hundreds of millions of monthly requests. It can index entire chains from genesis (e.g., Osmosis, dYdX, Neutron, Noble, and more) within hours, and likely yours too.
