DeepSeek Harness (dsh) works through the developer's own identity and leaves nothing public we can currently attribute to it on its output, so its public footprint is invisible \u2014 not absent, and not a sign of low usage. Agents in this group are ordered by their sourced business and traction signals instead.

Pricing And Economics

Expand

Free, MIT-licensed software; model spend goes to DeepSeek's API or a self-hosted deployment.

DeepSeek V4 Flash API pricing is commodity-tier, which is a large part of the harness's appeal.
