LogLens is a lightweight LLM observability platform that tracks and logs AI API calls with a single line of code.
LogLens is a lightweight LLM observability platform designed for developers shipping AI products. By integrating just a single line of code without requiring proxy setups or framework lock-ins, the platform automatically logs all OpenAI and Anthropic API calls made by TypeScript or Python applications. It tracks critical telemetry such as full prompts, completions, latency, token counts, costs, and errors. Additionally, LogLens features built-in email cost alerts to prevent unexpected overages, visual error tracking with exact error types, and a free tier with no credit card requirement.
Hot take: While enterprise LLM observability is dominated by heavy, proxy-dependent players, Loglens finds a sweet spot for indie hackers and startups by offering friction-free SDK integration and proactive cost protection without the burden of proxy latency.
* Single-line SDK integration for Python and TypeScript avoids the need for complex proxy configurations or network redirects.
* Proactive email cost alerts address a major developer pain point: unexpected billing spikes from runaway LLM loops.
* Detailed telemetry capturing prompts, completions, cost, latency, and specific error types simplifies debugging.
* Minimalist approach with a free tier makes it highly attractive for rapid prototyping and MVP development.
