Local-first dev AI: run a Claude-quality coding model & harness locally targets a $12.0B = 25M professional developers x $480/year (AI coding tools subscription avg $40/mo equivalent) total addressable market with medium saturation and a year-over-year growth rate of 30-45% — enterprise AI developer tools & local-inference adoption accelerating.

Key trends driving demand: Open-source weight releases -- leaked and permissive-model weights enable high-quality local alternatives that were previously cloud-only.; On-device inference improvements -- quantization and runtime libs now allow useful large-model inference on laptops and edge devices.; Privacy & cost pressure -- enterprises and freelancers want private, predictable-cost coding assistants.; Dev tooling consolidation -- teams prefer a single integrated harness (editor, CI, testing) rather than stitched-together scripts..
