Why LoneSock
Not a dev shop.
A technical partner.
We present our services alongside competitors -- you choose what fits. No lock-in, no forced stack. Auth0 vs Wenme, Twilio vs BitsPath, Casbin vs Darwan. Client decides.
Own Tier-3 data center
APNIC member, AS 64005, BGP peering. We operate real infrastructure -- not renting cloud capacity. Your data stays where you want it.
$20/hr -- no compromises
Bangladesh cost advantage with Silicon Valley engineering depth. The same principal engineer for 26 years. No bait-and-switch with junior developers.
Source code delivery
You own everything we build. Clean APIs, documented exports, no proprietary lock-in. You can leave. That conviction is why clients stay.
