Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
perf
Structured performance investigation with baselines, profiling, and evidence-backed decisions — run by AI agents inside your editor. `/perf` enforces a rigorous 10-phase methodology derived from recorded real investigation sessions: establish a baseline, identify the breaking point, generate hypotheses, profile, run controlled experiments, measure, document. No random micro-optimizations; every change is baselined, isolated, measured, and either kept or reverted with evidence. Designed to keep the agent honest in a domain where intuition is usually wrong.
ai.perfloop/perfloop
Always-on performance engineering for your own code: proven pull requests, the merge stays yours.
How to run each
perf
No data for an automatic command: what its marketplaces declare does not say unambiguously how to connect it.
ai.perfloop/perfloop As a remote MCP server
claude mcp add --transport http perfloop https://app.perfloop.ai/mcpCommands built only from what the marketplaces declare; the full set for every client is on each card.
Only ai.perfloop/perfloop has a remote endpoint we check. How we check endpoints
Tools each declares
