pretalx

It provides a web‑based workflow for conference organizers to run a Call for Papers, collect submissions, manage reviewer assignments, and schedule accepted talks. The system supports configurable submission forms, anonymous or open review, bulk e‑mail communication with speakers, and post‑event features such as slide uploads and embedding recordings. Export and import tools enable integration with other event‑related software.

The platform is aimed at event planners, program committees, and speakers who need a structured, transparent process for handling multi‑track conferences, workshops, or similar gatherings. Its open‑source code under the Apache‑2.0 license allows self‑hosting, while a public instance is also offered. Users can customize appearance and behavior through settings or plugins, and the project maintains active development with regular releases.

What distinguishes it is the combination of end‑to‑end conference management—CFP, review, communication, scheduling—within a single, extensible application that can be adapted to a wide range of event formats without requiring a subscription.
