Show HN: Lab – Local-first, serverless browser client for LLMs

Lab launched as a local-first, serverless browser client for large language models, debuting on Hacker News as a Show HN project. The tool runs LLM interactions directly in the browser without requiring a backend server, enabling users to work with language models entirely offline or with minimal infrastructure overhead.

The project prioritizes keeping data and computation local to the user's machine. By operating serverless, Lab shifts the operational burden away from cloud infrastructure, allowing users to maintain full control over their LLM workflows. The browser-based approach means no installation of local applications is necessary — users can access the tool directly through a web interface while retaining the privacy and performance benefits of local-first architecture.

Lab addresses a growing segment of developers and users seeking alternatives to cloud-dependent LLM interfaces. The local-first model sidesteps concerns around data transmission and storage on remote servers, while the serverless design eliminates the need to manage backend infrastructure. This combination appeals to users who want lightweight, privacy-conscious tooling for LLM tasks without operational overhead.

The project arrived with minimal fanfare on Hacker News, beginning with a single point and no comments at posting, suggesting an early-stage Show HN launch designed to gather feedback from the developer community.
