AntOmniEvo vs cindy

AntOmniEvo: AntOmniEvo is an auto-evolution framework from Ant Research that optimizes any system expressible as a directory of tunable files with a repeatable evaluation. You define the system, evaluator, data and artifact schema; the framework runs the loop while a coding-agent Proposer reads failure trajectories and edits the files.; cindy: Cindy is an open-source AI agent that brings several harnesses (Claude Code and Codex first), models and tools into one agent running locally on your machine with your real files and logged-in apps. Models and harnesses can switch mid-task while memory, skills and tools stay continuous, and it can drive your browser, computer and phone and take work from IM and schedules.

Features

AntOmniEvo logoAntOmniEvo
01Tunable artifacts are real directories (SKILL.md, pipeline.json, single-file algorithms), so optimization is plain file editing
02Coding-agent Proposer edits files based on failure trajectories
03Framework handles scheduling, budgets, selection and persistence in a resumable CandidateStore
04Delivers a diffable best candidate with change lineage tied to the failures that motivated each edit
cindy logocindy
01Claude Code and Codex harnesses with mid-task switching of harness and model
02Memory and skills shared across harnesses
03Browser, computer and phone control
04Bring your own model: Cindy service, existing Claude Code / Codex plans, your own API keys or local models
05Electron desktop and Expo mobile clients, Apache-2.0
