affromero/fairtrail — The price trail airlines don't show you.

Description and use

Fairtrail is a self‑hosted, open‑source service that continuously records airline ticket prices and lets users query historical price trends using natural‑language questions. By integrating a user‑provided LLM, it offers AI‑driven search and analysis of flight cost data, making it easy to spot price drops and optimal booking times. The project includes a backend API, data collection pipelines, and DevOps tooling for easy deployment and scaling.

Problem

affromero/fairtrail helps add AI capability without starting from a blank model stack.

Outcome

Medium: useful for prototypes or internal workflows, with dependency and maintenance checks before production.

Workflow

• prototype AI features
• build RAG or agent workflows
• evaluate model tooling

Evidence
