🛠️Build a Fully Local Coding Agent: A 2026 Walkthrough
TL;DR
Sebastian Raschka walks through setting up a production-style coding agent on a fully local stack. A locally served LLM pairs with a local harness that reads files, makes edits, runs commands, and verifies its own changes.

Key Points
Runs entirely on a self-hosted model, no external API calls
Harness handles file reads, edits, command execution, and verification loops
Covers model choice trade-offs for tool-use reliability and long context
Aimed at engineers who want privacy and cost control over hosted agents
Why It Matters
Local coding agents remove the API bill and data-exfiltration worry that block many teams from adopting agentic workflows, and open models are finally good enough to run them.
