Find software that’s real, verified, and reliable.
The intelligence layer for the world’s software.
Built on twenty years of real distribution by the team, technology, and reach behind Uptodown.
Not a store. Not a catalog. Atlas Cosmo maps what software is, what it does, how it runs, and why it can be trusted.
Every piece of software has an identity, a history, and a human context. We map and connect them into one navigable graph.
Atlas stores 2PB of data and processes information from over 250K files every day. At that scale, the graph becomes something more: a foundation for curated software sets tailored to specific needs and markets, from open-source ecosystems and enterprise deployments to age-appropriate collections and structured catalogs for AI agents and autonomous systems.
Security signals, scans, provenance, developer context, and risk classification. Readable by humans and machines.
Atlas holds over 30 million security reports linked to software identities, versions, developers, and distribution history. A single scanner verdict only tells you so much: Atlas connects that data to where software originates, how it moves across stores and mirrors, and who stands behind it. Software cybersecurity from the outside in.
Not just discovery. Installation, updates, compatibility, and rollback.
Running software requires more than finding it. Atlas knows which version works on which system, how installation and updates behave, and through which channels it can be obtained: store, package manager, CLI, direct download, or API. The full operational picture, across platforms and environments.
Tens of millions of apps, packages, and builds. Scattered across stores, registries, and repositories that don’t talk to each other.
Finding software is easy. Knowing what it does, whether it runs on your system, and whether it can be trusted is not.
This isn’t a concept. Since 2002, we’ve been doing the work: distributing files, tracking versions, scanning for security, curating editorial context, and building direct relationships with the developers behind the software.
