Claude Code vs DeepSeek Harness (dsh)
Both AI coding agents platforms, Claude Code (Terminal-first coding agent included in Claude Pro/Max/Team/Enterprise plans or billed via API; also IDE extension, desktop app and cloud sessions (cloud_agent).) and DeepSeek Harness (dsh) ('Everything is a Plugin' (Cordis) agent harness from DeepSeek; developer preview with breaking changes; general-purpose, not coding-only) go head to head here, priced from $17/mo and $0 + your model API bill respectively. Start with the bottom line, then the verified fact table and real production costs.
Claude Code leads four use cases to three because it publishes the product details buyers rely on. It shows a $20/mo entry plan with checkpoints and rollback for Beginners, a self-hosted or VPC option, SOC 2 and zero data retention for Enterprise, VS Code support, and a terminal CLI with project rules files. DeepSeek Harness (dsh) publishes none of those. DeepSeek Harness (dsh) wins the open side: it is MIT licensed with 242,300 GitHub stars and runs on your own API key with no published subscription, taking Open Source, Local Models and Free Plans. Its latest release is still a pre-release.

Claude Code vs DeepSeek Harness (dsh) pricing: true cost at 3 usage tiers
Real monthly cost at 3 developer profiles: hobbyist (~5 h/week), full-time developer (~25 h/week of daily agent use), team of 5. Most vendors do not publish how much usage a plan covers, so the full-time row spans the cheapest to the top individual plan unless the vendor publishes its own guidance for daily users. Bring-your-own-key and open-source agents show the model bill you pay the provider, never $0.Claude Code vs DeepSeek Harness (dsh): verdicts by use case
Beginners need a known bill and an easy undo. Claude Code publishes a $20/mo cheapest paid plan and offers checkpoints and rollback for reversing an agent's mistakes. DeepSeek Harness (dsh) publishes neither a paid plan nor rollback support; it runs on your own API key, and its latest release is a v0.2.0 release candidate, a pre-release. Claude Code is not included on the free plan, but it runs in a terminal CLI plus nine more surfaces, against a local web UI plus three more for DeepSeek Harness (dsh).
Claude Code covers the enterprise checklist, and DeepSeek Harness (dsh) publishes none of it. Claude Code offers a self-hosted or VPC deployment, SSO on Team and Enterprise, a zero data retention option, SOC 2 and admin audit logs, and its consumer plans leave training to user choice. DeepSeek Harness (dsh) does not publish a training policy, SSO, zero retention, SOC 2 or audit logs, so a security review would have nothing to evaluate.
Neither tool publishes a free plan allowance, so this comes down to how you start without paying. Claude Code is not included on the free plan, so agent work starts with its $20/mo paid plan, though it also supports bringing your own API key. DeepSeek Harness (dsh) is metered entirely on your own API key and publishes no subscription price, so you pay only your provider. Neither publishes local model support.
Neither tool publishes local model support or a list of supported providers, so no one can promise fully offline work here. The license tips it: DeepSeek Harness (dsh) is MIT licensed, so its model connection can be inspected and adapted, while Claude Code is proprietary. Claude Code supports bringing your own API key, and DeepSeek Harness (dsh) runs on your own API key, so both send requests to a provider you choose.
The license decides this. DeepSeek Harness (dsh) is MIT licensed and has 242,300 GitHub stars, so teams can read, fork and run it themselves. Claude Code is proprietary, published on npm under 'SEE LICENSE IN README.md'. Neither publishes supported providers, local model support or a hosted option, so the license and community size carry the result.
Where the agent runs matters most for shell work. Claude Code lists a terminal CLI first, plus nine more surfaces. DeepSeek Harness (dsh) leads with a local web UI, started with npx and served on 127.0.0.1:3080, plus three more. Both run terminal commands, offer background agents and support MCP. Claude Code also reads project rules files through nested CLAUDE.md files, which DeepSeek Harness (dsh) does not publish.
Editor support decides this, and only Claude Code publishes it: it works in VS Code and in Cursor through its VS Code extension. It also makes autonomous multi-file edits and offers checkpoints and rollback. DeepSeek Harness (dsh) publishes no editor support, multi-file editing, rollback or codebase indexing.
