Track AI code-model API usage without logins using open client-side telemetry

Track AI code-model API usage without logins using open client-side telemetry targets a $30.0B = 30M software developers x $1,000/year on tooling & observability total addressable market with low saturation and a year-over-year growth rate of 25-40% (developer toolchains & observability growth driven by AI adoption).

Key trends driving demand: LLM embedment in developer workflows -- more editor plugins, CI hooks, and SaaS features call code-generation models, creating telemetry sources.; Cost and billing transparency -- teams need per-feature and per-endpoint breakdowns to control LLM spend.; Open-source observability renaissance -- self-hosted analytics and privacy-friendly tooling are getting traction as alternatives to closed SaaS.; Model-agnostic instrumentation -- demand for tools that work across OpenAI, Anthropic, and private models increases cross-vendor utility..
