AgentLoop vs Rosply: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of AgentLoop and Rosply — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
AgentLoop
Edward Yi
AgentLoop turns a single ChatGPT plan into unattended Codex worker + independent-critic cycles that build against your local rubric until the work passes.
Key features
- Fresh Worker Per Cycle: Each build cycle spawns a clean Codex worker with fresh context so long-running loops do not accumulate stale state or memory drift.
- Independent Critic Process: A separate fresh process grades every result against your rubric so passing tests never become permission to stop looking.
- Rubric in GUIDELINES.md: Definition-of-done lives as plain Markdown in your repo and is read on every cycle, so standards persist while prompts do not.
- Evidence Carried in Files: Worker output, critic verdicts, and fixes are written to project files so the next cycle inherits the actual state of the work.
- Bounded Goal + Cycle Budget: You cap the loop with a goal.md and cycle budget so unattended runs stop at a predictable ceiling.
- MCP Status Interface: Ask ChatGPT for status through MCP so you can monitor cycles, verdicts, transcripts, and cost without opening the dashboard.
- Local-first Install: git clone the pinned v1.1.0 release and run node src/daemon.js — no npm install, no hosted workspace, MIT licensed.
Best for
- Shipping a bounded feature: Add a CSV export across UI, API, and regression suite while the critic enforces end-to-end behavior and edge cases.
- Migration work: Run an unattended migration where fresh workers apply the change and the critic verifies each step against a rubric.
- Hardening pass: Give AgentLoop a hardening goal so it iterates on defects the existing test suite misses, like malformed input handling.
- Product polish loop: Point AgentLoop at a polish goal with clear acceptance criteria and let it converge to VERDICT: PASS.
- Unattended overnight runs: Kick off a long loop, monitor cycle verdicts, and cancel from the dashboard or via MCP when the receipt looks right.
- Enforcing team standards: Codify team engineering standards in GUIDELINES.md so every worker builds against the same definition of done.
Rosply
Rosply
Rosply is an AI desktop agent that automates repetitive Windows tasks by viewing the screen and controlling mouse and keyboard like a human.
Key features
- Vision-Based Control: Takes a screenshot every step and reads dialogs, popups, and dynamic UI like a human, with no DOM scraping or XPath required.
- Cross-Application Automation: Controls Chrome, Excel, VS Code, and legacy enterprise software—anything that runs on the desktop—without plugins.
- Instant Halt Control: Press Ctrl+H at any moment to immediately stop the agent, or close the terminal window for a clean exit.
- Multi-Platform Support: Fully tested on Windows 10/11, supported on Linux, and functional in beta on macOS, with mouse, keyboard, and screenshot control on all.
- Model-Agnostic via OpenRouter: Sends only screenshots and task text to OpenRouter, letting you pick the underlying AI model.
Best for
- Repetitive Data Entry: Automating form-filling and data transfer across desktop apps without scripting.
- Legacy Software Operation: Driving old enterprise tools that lack APIs by interacting through the visible UI.
- Spreadsheet Workflows: Performing multi-step Excel tasks autonomously from a plain-text instruction.
- Browser Automation: Navigating and completing tasks in Chrome the way a person would.
