Latest News
Products & Services
An open-source, headless SaaS backend and hosted service for AI assistants and agents. It provides records, files, team accounts, permissions, notifications, and audit logs through an HTTP API, MCP, and CLI; it can run on Bun with SQLite or PostgreSQL and can be self-hosted.
A GitHub Action that turns commits and other comments into poetry and can post a poem to a pull request. It uses a small fine-tuned 4-bit model; the associated Q4_K_M GGUF is based on Qwen3-0.6B and is intended for CPU inference with llama.cpp.
An open-source Python library for downloading closed captions/subtitles from YouTube.
A 4-bit quantized 0.8B-parameter text-generation model published by Mike Lay on Hugging Face to power PR Poet; the model page lists a 484 MB GGUF for CPU inference.
Market Position
The Last SaaS is positioned as a headless, agent-first SaaS foundation: its differentiator is bundling common SaaS primitives—records, files, accounts, permissions, notifications, and audit logs—behind MCP, an API, and a CLI, while remaining open source and self-hostable. PR Poet occupies a lightweight developer-automation niche by using a small fine-tuned model rather than requiring a large hosted model.
