C++ on Sea is an international C++ conference taking place by the sea, in the UK. Our physical venue is in Folkestone, Kent, near the entrance to the channel tunnel.

New for 2024! We'll be running a new online event called C++ Online! This will run from 7th to 9th February 2024 with a pre-conference workshop day on the 6th. More details will be published here in the near future.

Our 2023 in-person event ran from 27th-30th June (including the workshops day). In 2024 we'll also be back in-person at the usual venue on 2nd-5th July.

Announcing: C++ Online 2024!

C++ Online...

During the pandemic we moved online out of necessity, as did many other conferences. One positive side effect of that move was that we realised our events could reach people who might not otherwise be able to attend - for all sorts of reasons. So as we started meeting in person again, many events - C++ on Sea included - attempted various hybrid formats. Due to limitations in the internet infrastructure at our venue we weren't able to live stream sessions, so in 2022 we tried a staggered approach. We held a full in-person event one week. Then the following week we held an online event with a mixture of content recorded the week before (with the speakers live in the chat and Q&A), some speakers returning to redeliver the same talks online, and some entirely new live content online.

This was a qualified success. Running the event a week later turned out to be a significant overhead and not really sustainable. But we don't want to give up on this idea!

So we have decided to split this online component out into its on event. We're calling it: C++ Online.

While we may include some pre-recorded content, again, the majority of the sessions will be fully live. We'll be able to hear from some speakers who have still not been able to resume travelling (or would prefer not to) but - perhaps even more importantly - also reach a whole range of people who are not served by a physical event.

We learnt a lot about running online events during the pandemic - and we're still learning, still iterating. Let's use that to put on the best online event we can and reach all parts of our community.

C++ Online will run from 7th-9th February 2024, with a workshops day on the 6th. Early bird tickets will open soon. In the meantime the Call for Speakers is now open and will run until the end of October.

Don't worry, if you prefer in-person events, C++ on Sea is not going away. We'll be back next July. We'll announce those dates, and open the Call for Speakers for that in the next few weeks.

Whatever type of event works for you, we hope to see you there!

C++ on Sea is hosted at the Leas Cliff Hall in Folkestone in Kent, UK, overlooking the English Channel. This historic seaside town is also home to the channel tunnel and, as such, has excellent links to the rest of europe. It's also very accessible from London with the UK's (currently) only high speed link, the HS1. For more comprehensive travel information, see the page, Getting to C++ on Sea

The Leas Cliff Hall is a working theater that also has a dedicated conference suite. Built into the cliffs, and with floor-to-ceiling glass overlooking the sea on three sides, the views are spectacular!

The venue is about a 15 minute walk from Folkestone Central station, or ten minutes walk to the bustling town centre. As well as the modern town the old quarter, home to art galleries, curio shops and bohemian cafes and restaurants, extends down to the picturesque harbour.

Although the venue is split across three floors, connected via staircases, it is also fully accessible via elevator.
