deepseek-harness alternatives

Curated alternatives to deepseek-harness — and why you'd switch.

trueforge

TrueFoundry's open agent harness: the runtime loop — model calls, MCP tools, SKILL.md packs, sandboxing, approvals, compaction — behind a chat UI, HTTP API, TypeScript SDK and embeddable UI.

Why switchTwo open agent harnesses with a UI, an API and a plugin story. TrueForge is the more finished product — catalogs, sandboxing, approvals, compaction, Helm charts; dsh is a plugin substrate on Cordis in developer preview. Ship on TrueForge, watch dsh.

maka

Apache-incubating agent workspace where the append-only run log IS the runtime: desktop, TUI, CLI and Eval are thin clients of one host, and every harness benchmark ships with per-task records.

Why switchTwo open agent harnesses with desktop and CLI surfaces and a plugin story. DeepSeek's dsh bets on composability (everything is a plugin); Maka bets on the log and on measured, verifier-checked task completion.

goose

General-purpose local AI agent in Rust — native desktop app, full CLI and embeddable API — over 15+ providers and 70+ MCP extensions. Block's goose, now an Agentic AI Foundation project.

Why switchDeepSeek's plugin-everything agent harness covers the same ground from the model-vendor side. Goose is the packaged, foundation-governed option with a desktop app and a large extension ecosystem; the DeepSeek harness is closer to reference code you extend.
