DConf 2026: D Language Conference Set for London
28 Jul 2026
DConf 2026 Set for September in London
DConf, the annual conference dedicated to the D programming language, will return in 2026 with an in-person event in London running September 2–4. The conference is organized by Symmetry Investments and the D Language Foundation, in partnership with Brightspace Events and CodeNode. DConf has run annually since 2013, making the 2026 edition part of a well-established tradition in the D language community.
For founders and engineering teams working with or evaluating D, the event offers a rare concentrated touchpoint with the language's core community — including its primary corporate backer, Symmetry Investments, whose continued sponsorship may signal ongoing industry-side interest in D for finance and systems programming use cases.
Key Dates
- April 7, 2026 — General registration opens
- May 24, 2026 — Submission deadline for talks
- June 5, 2026 — Schedule published
- September 2–4, 2026 — DConf 2026 held in London
- September 2, 2026 — General registration closes
Registration will remain open for nearly five months, from April 7 through the first day of the conference itself, giving prospective attendees a wide window to plan.
What's Available Remotely
Organizers have confirmed that livestreams will be available for those unable to attend in person. This could lower the barrier to entry for founders and developers outside the UK who want to follow talks without travel costs — though the report does not specify whether sessions will be archived or made available on-demand after the live event.
A Platform for Showcasing D-Language Work
With submissions due May 24 and the schedule set to publish June 5, early-stage founders or engineers building on D may have a window to pitch talks and showcase projects or tools to a niche but engaged technical audience. Given the conference's history of annual return since 2013, this audience appears to represent a stable, if specialized, ecosystem rather than a fast-growing one.
A Logistical Note for International Attendees
Visitors from certain countries will need to apply for a UK Electronic Travel Authorization (ETA) as a required entry document. Founders based abroad and considering in-person attendance should factor this into travel planning, as it adds a step — and potential lead time — beyond standard registration.
What We Don't Know Yet
Several details remain unpublished as of this report:
- Ticket pricing or registration fees
- The speaker lineup or session topics
- Specific CodeNode venue details or capacity
- Whether recorded talks will be posted after the event
- Expected attendance size or historical DConf turnout
Founders relying on a single source for event details should treat these gaps as open questions to confirm directly with organizers before committing travel budget or submission time.
Why Founders Should Care
For most early-stage founders, DConf 2026 is unlikely to be a must-attend event — D remains a niche language, and the conference appears modest in public-facing detail. However, for teams building systems-level or performance-critical software, the event may offer a low-cost (via livestream) or moderate-cost (via in-person attendance) way to engage directly with the D Language Foundation and Symmetry Investments, a notable financial-sector backer of the language. The annual cadence since 2013 suggests the community is stable rather than shrinking, which could matter for founders weighing long-term reliance on D in their stack. Given the limited public details on cost and lineup, founders should likely treat this as a wait-and-confirm opportunity rather than an immediate calendar commitment.
