Best Open-Source Agent Harnesses for Local LLMs in 2026

A 2026 guide ranks 11 open-source agent harnesses, including OpenCode, Goose, Cline, and OpenHands, by local-LLM support, licensing, and safety controls.

The guide ranks 11 open-source LLM agent harnesses by OSI license, documented local runtimes, maintenance status, and safety controls, using GitHub data read September 18, 2026. OpenCode documents Ollama, LM Studio, and llama.cpp setups across 75+ providers; Pi offers a minimal four-tool harness and was acquired by Earendil in April 2026; Goose is Rust-based with 70+ MCP extensions under the Linux Foundation's Agentic AI Foundation. Cline defaults to per-action approvals, while OpenHands recommends Qwen3.6-35B-A3B with at least 24GB VRAM and 32,768-token context.

SoL-Pi: Recursively Scaling Auto-Research Loops for Efficient Agent Harness

SoL-Pi scales auto-research loops to produce an agent harness matching Pi while cutting token traffic 44.7-49.0% and API cost by a third.

The paper takes an RSI-inspired approach at the harness layer, scaling auto-research loops across increasingly numerous and diverse environments to yield reusable improvements that transfer beyond their development setting. Four mechanisms survived selection to form SoL-Pi, spanning action execution, context compaction, observation handling, and delegated reading. On the 51-task EdgeBench evaluation, SoL-Pi achieves performance comparable to Pi across GPT-5.6 Sol and Opus 5 while reducing recorded token traffic by 44.7-49.0% and API cost by about one third. Estimated hourly savings are $8.75-13.50 relative to native Codex and Claude Code harnesses.
