Multi-LLM agent framework with Claude Code-like tools. Use DeepSeek, Claude, GPT, Llama, or any model — same tools, same skills, swap freely. Includes file editing, code search, shell execution, sub-agents, and a production-ready API. The missing SDK between your LLM and your codebase.

ToolLoop

Multi-LLM agent framework with built-in tools for any model.

ToolLoop gives you agentic coding capabilities — file editing, code search, shell execution, sub-agents, skills — while letting you swap LLMs freely. Use DeepSeek for cheap tasks, DeepSeek for complex ones, GPT for everything in between. Same tools, same prompt, different brains.

10-Line Demo

from sdk import query, ToolLoopOptions

async for event in query(
    prompt="Find all TODO comments in this repo, fix them, then run the tests",
    options=ToolLoopOptions(
        model="bedrock/converse/deepseek.v3.2",  # or any LLM
        allowed_tools=["Read", "Edit", "Grep", "Glob", "Bash"],
        workdir=".",
    ),
):
    print(event)

Why ToolLoop?

Most agentic coding tools such as Claude Code are locked to a single LLM provider. ToolLoop breaks that lock.

Core Value Propositions

1. Multi-LLM with Smart Model Routing Use DeepSeek V3.2 ($0.62/M tokens) for file search and simple tasks, DeepSeek ($3/M) only when you need it. Switch models mid-conversation — start cheap, escalate to powerful. Same tools, same skills, 5x cheaper on routine work.

2. Customizable Reasoning You control every tool implementation and the agent loop itself. Modify how Edit works, add domain-specific tools, change the orchestration logic. Most agentic tools are closed-source black boxes.

3. Production Deployable SDK Most agentic coding tools are CLIs for developers. ToolLoop is an API you ship to customers — FastAPI + WebSocket + Docker sandbox + multi-tenant session isolation, ready for production. Or embed it in your product with 10 lines of Python.

4. Skills Portability Load skills from the SKILL.md ecosystem. Community skills work instantly across DeepSeek, GPT, Llama, DeepSeek, and DeepSeek. Skills aren't locked to one vendor.

5. No Vendor Lock-in If a provider has an outage, rate-limits you, or raises prices — switch models with one confi
