pretalx is a conference planning tool focused on providing the best experience for organisers, speakers, reviewers, and attendees alike. It handles the submission process with a configurable Call for Participation, the reviewing and selection of submissions, and the scheduling and release handling. After the event, pretalx allows speakers to receive feedback, upload their slides, and organisers to embed recordings.

In short: pretalx takes a conference from "we should do a call for papers" all the way to "here is the published schedule" – and everything in between.

What pretalx does for you:

• Call for Participation – a fully configurable submission process with custom questions, tracks, and session types.
• Reviewing & selection – collaborative reviews, scoring, and team-based workflows to curate your programme.
• Scheduling – build, version, and release schedules across rooms and days, with public agenda and per-speaker views.
• Speaker communication – templated, queued emails, invitations, and post-event feedback.
• Integrations – a documented REST API, an extensible plugin system, and full internationalisation.

Read our feature list on our main site to get a better idea of what pretalx can do for you, but it typically involves everything you'll need to curate submissions and contents for a conference with several tracks and conference days.

You can host pretalx yourself, as detailed in our administrator documentation, or use our public instance at pretalx.com. Self-hosting runs on Python (3.12+) with PostgreSQL and Redis; the docs walk you through both a Docker-based and a manual setup. If you want to follow along with new versions and upcoming features, we recommend our blog.

pretalx is highly configurable, so you can change its appearance and behaviour in many ways if the defaults don't fit your event. If the settings are not enough for you, you can even write plugins of your own.

pretalx is under active development and used by many events. It supports everything required for talk submission, speaker communication, and scheduling. You can see our supported features in the feature list, and our planned features in our open issues. pretalx has regular releases – you can look at the changelog to see upcoming and past changes, and install pretalx via PyPI. Our CI gate is 100% test coverage, so changes land with confidence.
