Clono is an electronic scoresheet and live broadcasting system for chess tournaments, developed by Ole Kristian Valvåg in Tromsø, Norway. It replaces traditional paper scoresheets with Clono Scoresheet on tablets, sends game data to Clono Server, and then broadcasts games online via Clono Chess Cast or third-party platforms. The official website emphasizes that it is FIDE-approved and can be used for official chess events.
The system is built around tournament creation, board assignment, electronic scorekeeping, and live viewing. Administrators can create events in the Admin Panel, configure tournament details, time controls, sections, and players, and also import tournament XML from TournamentService. After each round is paired, player and game information is pushed to the tablets assigned to each board, where it is displayed as an electronic board card. During the game, players enter moves on a graphical chessboard and can correct them using the back button. After the game ends, the result is recorded, and the tablet becomes a result card while waiting for the next round’s pairing. On the broadcast side, Clono supports both single-game pages and multi-game side-by-side viewing, with configurable broadcast delay. For third-party integrations, Clono can provide live feeds to sites such as Chess24, Chessbomb, and Lichess.
Clono is currently 100% free to use, with no ads on the website or in the app; the developer accepts donations to support ongoing development. In terms of deployment, the available materials state that games are sent to Clono Server and published online, so it operates as a cloud service. It is not stated whether self-hosting is supported. The official website does not disclose any commercial edition, SLA, paid support, or specific payment methods.
The main advantage is its low barrier to entry: it does not require electronic boards, cabling, or on-site engineers, making it suitable for quickly setting up live broadcasts for small and mid-sized tournaments. It is also free, ad-free, FIDE-recognized, and relatively intuitive for players to use. The limitations are that the product is highly vertical and only suited to chess events. Common enterprise software features such as team permissions, audit logs, data compliance, API documentation, and support processes are not disclosed in the main content, leaving some uncertainty around long-term availability and service guarantees.
Clono is suitable for chess associations, clubs, school tournaments, open tournament organizers, and arbiter teams that need electronic scorekeeping, multi-board on-site display, and online broadcasting. The official website does not specify accessibility from mainland China, so direct access, broadcast latency, and donation payment availability all need to be tested in practice. If localized service or a more mature hardware ecosystem is required, alternatives to compare include Lichess broadcasts, ChessBase/LiveChess, DGT LiveChess, and TournamentService.
