Why we built Foundry
A developer everything-app — omnibar, sandboxes, calc, HTTP client, todos, notes — built because no single tool did all of it under one hotkey.

Long-form engineering, infrastructure, and product writing from the team that builds Atlas — deep-dives on how we ship the systems that hold up the wire.
How we build it. Deep-dives on architecture, language choices, and the trade-offs behind production systems at Atlas.
Bare metal, networking, edge, and the unglamorous work that makes the rest fast. CDN tuning, BGP, hardware teardowns, and capacity stories.
Threat models we lived through. Anti-cheat, DDoS, abuse, and the patterns that show up across every Atlas product.
Why a feature exists, how it shipped, and what the data said afterwards. Product notes for the people who use Atlas.
Atlas as an organization. Hiring, principles, milestones, and the occasional behind-the-scenes.
A developer everything-app — omnibar, sandboxes, calc, HTTP client, todos, notes — built because no single tool did all of it under one hotkey.
TTFB optimization ignores the layer that owns most of it. The math behind 1-RTT TLS 1.3, 0-RTT replay, OCSP stapling, and post-quantum handshake fragmentation.
Volumetric DDoS isn't 'solved' — it's absorbed. The math behind 51,000× memcached amplification, anycast scrubbing, and the four-class threat model behind modern defense.
