# Compare AI on your task.

Try your task. Choose the result you prefer. Keep using it.

## Compared by you, or your agents

Send the task above yourself, or paste one instruction into the agent you already use and let it run the comparison through the API.

## Common comparisons

| Comparison | Description | Link |
| --- | --- | --- |
| Claude Code vs Codex | Try your task. Choose the result you prefer. Keep using it. | [Compare your task](/content/claudecode/vs/codex/index.html) |
| DeepSeek Harness vs Codex | Two house pairings: OpenAI's harness on GPT models, DeepSeek's on its own. Your task decides. | [Compare your task](/content/deepseek/vs/codex/index.html) |
| Claude Code vs DeepSeek Harness | Two first-party harnesses from opposite ends of the price list. Run your task and read the receipt. | [Compare your task](/content/claudecode/vs/deepseek/index.html) |
| Claude Code vs Hermes | Claude Code is built around code and files; Hermes runs any model on everything else. | [Compare your task](/content/claudecode/vs/hermes/index.html) |
| Claude Code vs OpenClaw | Claude Code works a task and stops; OpenClaw keeps going. A long goal shows the difference. | [Compare your task](/content/claudecode/vs/openclaw/index.html) |
| Codex vs pi | Codex is the full coding harness; pi is deliberately small and lets you steer it mid-run. | [Compare your task](/content/codex/vs/pi/index.html) |
| Hermes vs Kimi Code | Both run a wide range of models, so the harness itself is what you compare. Bring a multi-step task. | [Compare your task](/content/hermes/vs/kimicode/index.html) |
| Claude Code vs DeepSeek Harness vs Codex | Try the same task. Choose your favorite result, then keep going. | [Compare your task](/content/claudecode/vs/deepseek/vs/codex/index.html) |

## The decision

### Buy the layer you do not want to maintain.

1. **Choose a model API** - when your product needs model output and your team already owns the agent loop, computer, state, and integrations.
2. **Choose an agent SDK** - when you want to build the agent behavior yourself and are ready to supply the runtime and operations around it.
3. **Choose a DIY runtime** - when infrastructure control is the product advantage and your team wants to maintain every harness, sandbox, and recovery path.
4. **Choose AgentSky** - when your product needs the working agent and its computer through one API, while keeping the freedom to choose the supported harness and model.

## Platform comparisons

### AgentSky vs the alternatives

These pages compare AgentSky to infrastructure tools that builders often evaluate alongside it. Each covers what the tool actually is, a feature-by-feature table, and when to choose each.

- **AgentSky vs HarnessRouter** - Both offer managed harness infrastructure. HarnessRouter also publishes a self-hosted Community Edition; compare the workflow and deployment you need. [Read comparison](/content/compare/agentsky-vs-harnessrouter/index.html)  
- **AgentSky vs E2B** - E2B gives you a Firecracker microVM and an SDK — you assemble the agent. AgentSky gives you the running agent. [Read comparison](/content/compare/agentsky-vs-e2b/index.html)  
- **AgentSky vs Modal** - Modal is built for ML training and batch inference. AgentSky is built for long-running agentic task completion. [Read comparison](/content/compare/agentsky-vs-modal/index.html)  
- **AgentSky vs OpenRouter** - OpenRouter offers routing, Agent SDK, Ori and beta containers. Compare the execution path with AgentSky hosted agents. [Read comparison](/content/compare/openrouter-vs-agentsky/index.html)  
- **AgentSky vs LiteLLM** - LiteLLM unifies 100+ LLM APIs behind one proxy. AgentSky runs the complete agent on persistent cloud compute. [Read comparison](/content/compare/litellm-vs-agentsky/index.html)  
- **AgentSky vs Portkey** - Portkey adds routing, caching, and observability to LLM calls. AgentSky runs the full agent on persistent compute. [Read comparison](/content/compare/portkey-vs-agentsky/index.html)
