RustConf 2026 Heads to Montréal With New Session Types and Open Registration

The Rust Foundation opened registration for RustConf 2026 on Wednesday and confirmed the first wave of speakers for the September 8-11 event, which will be held in Montréal with a simultaneous online attendance option. Early-bird pricing runs through April 29.

The session that will get practitioners talking: Canonical systems engineer Jon Seager is scheduled to deliver a keynote on how Ubuntu shipped Rust-based rewrites of two foundational system packages, coreutils and sudo. That is not a proof-of-concept or a side project; it is a distribution-level commitment that ships to millions of machines. For a community that has spent years cataloguing incremental crate adoptions, Seager's session represents something qualitatively different: evidence that Rust is now operating at the layer where operating systems make package decisions.

The closing session pairs Rebecca Rumbul, Executive Director and CEO of the Rust Foundation, with Deb Nicholson, Executive Director of the Python Software Foundation, in a fireside chat covering cross-ecosystem interoperability, security priorities, and governance lessons. The pairing carries real weight given how deeply Python's tooling layer has come to depend on Rust-backed infrastructure in recent years. A direct conversation between the two foundations' executive leadership signals that the relationship between these ecosystems is becoming formal enough to warrant structured dialogue at the conference's highest-profile slot.

The 2026 program also introduces two new session formats. Community Lightning Talks give community members five minutes each for focused deep dives, a format historically effective at surfacing sharp technical insights that don't fit a standard talk slot. Project Updates are short presentations from people directly embedded in specific Rust projects, designed to close the gap between maintainer knowledge and practitioner awareness.

The Montréal edition is positioning itself as an expanded version of the conference's usual contributor-and-enterprise mix, and the added session diversity gives teams more surface area to justify attendance in their Q3 planning. Early-bird tickets remain available through April 29, with both in-person and online registration now live.

The Ubuntu keynote alone reframes what this year's RustConf is really about: not adoption as aspiration, but Rust already running beneath the operating system infrastructure that ships by default on production servers around the world.
