Conference focus

Three lanes, one very C++ audience.

The programme is broad enough to stay interesting.

namespace language

Core Language & Library Design

API design, templates, constexpr, generic programming, modern idioms, type systems, safety, and the future shape of the language.

templatesbenchmarksclang
namespace systems

Performance, Systems & Infrastructure

Low-latency engineering, memory behavior, lock-free design, observability, throughput, reliability, and what happens outside toy examples.

templatesbenchmarksclang
namespace tooling

Tooling, Compilers & Developer Experience

Build pipelines, clang-based tools, packaging, static analysis, IDEs, refactoring, codebase scale, and faster paths from edit to insight.

Why C++ Fall 26

Built for C++ people.

Everything here is designed to reward technical curiosity, taste, and the ability to appreciate a good benchmark chart.

Zero-cost abstractions

Talks that respect performance reality

No hand-wavy futurism. Expect code, benchmarks, trade-offs, build pain, and the kinds of details only practitioners bother to argue about.

Tooling renaissance

Compilers, build systems, static analysis, and debuggers

From clang internals to editor workflows to modern CI and package management, this is where the people doing the hard work compare notes.

Language evolution

Where modern C++ is actually going

Executors, reflection, safety, modules, ergonomics, performance portability — ideas discussed by people who understand both the standard and the field.

Systems people

A crowd worth meeting

Library authors, engine programmers, compiler engineers, infra leads, finance, embedded, graphics, robotics — exactly the kind of hallway track you hope for.

What people say

The kind of praise that sounds like a code review compliment.

Short, specific, and from exactly the sort of people you want in the room.

Finally, a C++ event where the talks assumed the audience had a profiler and knew how to use it.
MK
Mina Kovács
Compiler Engineer
Dense, technical, opinionated, and weirdly elegant. Exactly what a good C++ conference should be.
DM
Daniel Mercer
Game Engine Programmer
The hallway track alone was worth the trip. I left with ideas for tooling, hiring, and a library redesign.

Staff Systems Engineer
Call for speakers

Have a sharp idea, a hard-earned lesson, or a benchmark with a story behind it?

We want talks from people who have built real things, measured them honestly, and have something useful to say to other serious engineers.

patch welcome

Submit a proposal.

Great talks can be deeply practical, surprisingly opinionated, narrowly technical, or elegantly conceptual — as long as they are grounded in real engineering.
