Modern C++ for production

A Wrocław-based community for C++ developers building production systems where safety, performance, security, and resource discipline all matter at once.

wro.cpp is a Wrocław-based community for C++ developers building production systems where safety, performance, and resource discipline matter. We cover modern C++ end-to-end: from C++26 reflection through lifetime safety, low-latency patterns, and the tooling that makes C++ ship in regulated industries.

Two front doors: the blog is the timeline (deep-dive series + news short-form), the Toolset is the evergreen reference. Posts feed the toolset; the toolset feeds posts. Both default to premium open source and runnable claims (every example links to a Compiler Explorer URL we re-verify on every publish).

What you'll find here

  • Flagship technical posts (English) — hands-on deep dives into modern C++: the C++26 reflection series, the upcoming Production C++ series (safety, performance, security, compliance), language features, patterns, case studies.
  • Short-form posts — news roundups ("C++ This Fortnight"), tool spotlights, problem-solutions, conference recaps.
  • Toolset reference — opinionated picks across compilers, sanitizers, profilers, AI agents, local LLMs, hardened stdlib, qualified compilers, coding standards. Each section has a freshness badge, a "Reproduce locally" container, and a machine-readable companion at /toolset/<slug>/llms.txt for AI agents.
  • Events — monthly online meetups and quarterly in-person gatherings in Wrocław, often in Polish.

Talk to us

Talk to the wider C++ committee

The 2026 Annual C++ Developer Survey "Lite" is open through mid-May. 10 minutes of feedback that the ISO C++ standards committee and the major tool vendors (GCC, Clang, MSVC, Bloomberg clang-p2996, NVIDIA, Intel) all read directly. If you ship C++, this is the single highest-leverage feedback channel available to you. wro.cpp is amplifying the call to action because the responses shape what lands in C++29.

Who runs it

Currently a solo effort by Filip Sajdak, with the intent of growing editorial help from the Wrocław C++ community. Guest posts welcome via the contribute page.

A note on the name

The .cpp is the one every C++ developer types a hundred times a day — it's the source-file extension. So the community mark is wro.cpp, a filename you'd find in any of our repos. The horseshoe-magnet logo is from the 2021 brand book, unchanged.
