One comparison protocol for every pair

Each pair page will lock the current versions, clean repository state, task prompt, model/provider where possible, network conditions, permission policy, and success criteria. Runs will retain time, token/accounting data when exposed, tool calls, changed files, tests, retries, and failures.

  • Same repository commit and task prompt.
  • Same model/provider when both products support it.
  • Equivalent permission boundary.
  • At least three runs when variability matters.
  • Raw observations separated from interpretation.

Measure the dimensions that change a decision

Installation and setup cost matter for first use. Provider flexibility, tools, Skills/plugins, MCP, subagents, session persistence, UI, permission controls, speed, tokens, stability, and failure recovery matter during repeated use. A winner can differ by task and operating constraint.

Current comparison queue

Current search and community evidence supports researching Claude Code, OpenCode, Pi, and Reasonix. The pages exist in the local build but remain noindex until direct tests meet the shared protocol.

  • DeepSeek Harness vs Claude Code: current Suggest/SERP demand and entity confusion.
  • DeepSeek Harness vs OpenCode: direct community speed/token comparisons.
  • DeepSeek Harness vs Pi: existing competitor coverage creates a high information-gain bar.
  • DeepSeek Harness vs Reasonix: emerging comparison demand; Web strength remains uncertain.

What this site will not call a benchmark

One anecdotal run, different models, different repositories, a marketing feature table, or a copied community opinion does not become a HarnessBase benchmark. If a dimension cannot be controlled, the page will say so.

Sources and evidence boundary

Primary sources establish product facts. HarnessBase labels direct testing separately and does not convert community observations into verified results.
