Share. Learn. Inspire.

Join the major European event for Erlang, Elixir and Gleam users

Our goal is simple: to create a vibrant platform where users of Elixir, Erlang, Gleam and other technologies based on BEAM VM can come together to share insights, get feedback on projects, and inspire each other to new heights.
Code BEAM has united Erlang & Elixir developers for years to grow and progress the community in the spirit of Share. Learn. Inspire.

Meet people and companies using and developing high performance, fault-tolerant and resilient applications that scale to billions of users in production in areas like Fintech, eCommerce, IoT, Gaming, Blockchain, Security, Machine Learning and more.

DIVERSITY AND INCLUSION PROGRAMME

This year thanks to AppSignal we are able to run our Diversity and Inclusion Programme again. The goal of the programme is to broaden access to the conference and provide support to individuals who might not otherwise have the opportunity to attend. The programme focuses on empowering individuals new to Erlang, Elixir and Gleam startups, and those from varied backgrounds, everyone is welcome to apply.

INFORMAL SPACE


This year we're hosting a community-led informal space alongside the main programme. It may include all sorts of activities that would not exactly fit the talk format. Possible experiences you may find in this area will include: demos, panel discussions, slightly larger lightning talks, games, talks in languages other than English, hacking sessions and any other cool activity you can think of. If you have an idea of some informal activity you want to engage in or coordinate, let us know and we'll do our best to include it in the Informal Space. This will shape up closer to the conference or at the conference:)

CONFERENCE VENUE

PHIL

Lange Begijnestraat 11, 2011 HH Haarlem, The Netherlands

PHIL sits in the heart of Haarlem's old town, surrounded by shops, cafés and restaurants and a few minutes' stroll from the Grote Markt. Haarlem is one of the easiest cities to reach in the Netherlands: it's a direct, ~15-minute train ride from Amsterdam Centraal and around 30 minutes from Amsterdam Schiphol Airport.

By train & public transport

Haarlem Centraal station is a 10-minute walk from PHIL, with direct trains from Amsterdam Centraal (~15 min) and Schiphol Airport (~30 min). Plan any train, bus or tram journey with the Dutch journey planner 9292.nl.

By car & parking

You can't drive up to the entrance, so park in one of the nearby public garages and walk the last few minutes:

  • De Appelaar — Damstraat 12 — right next to PHIL (~1 min walk). Closest option, but fills up quickly.
  • De Kamp — De Witstraat 1 — ~5 min walk.
  • Station Haarlem (Interparking) — ~10 min walk. Large, usually has space, and the only garage where you can reserve a spot online in advance.
  • Raaks — Zijlvest 45 — ~9 min walk.
  • Houtplein — Wagenmakerslaan 1 — ~13 min walk.

By bike

PHIL has no bike racks of its own. Use the free, covered and guarded bike parking on the Smedestraat, about 250 m away.
