The official site says the game can be played with an invented peloton or with “the 2026 season as it really is”, and lists a UCI calendar with monuments and Grand Tours; the itch.io downloads are named “real-2026”, and the developer's Reddit post says a real-world 2026 pack is in the works. We did not open the builds to see which real riders, teams or races they name. No source mentions a licence from riders, teams, race organisers or the UCI. (bordure-game.com)

About Bordure
Bordure is a cycling management game for Windows and macOS, in an early alpha. You are the directeur sportif, never a rider: you never choose a power output, a line or the moment of an attack. Before a race you set a team plan with objectives, roles and missions for each phase; during it you follow a live feed with timings, elevation and events and send radio orders such as “cover the break” or “protect the leader until the foot of the climb”. Orders take time to arrive, must be acknowledged, and are carried out according to each rider's character, or not at all; repeating them does nothing, and a race runs to a sensible finish on the plan alone. Rival teams use the same plans, rules and perception as yours, and you only know what your car knows: every gap and position shows its source and age. Under the hood are speed physics with gradient, aerodynamics and drafting, two energy reserves, crosswinds and echelons, rain, cobbles, gravel, time trials and Grand Tours, all deterministic, so the same seed and orders give the same race at any playback speed. Between races there is a multi-season career with calendar, training blocks, contracts negotiated live with agents, sponsors, national teams and a Draft mode, and teams, riders and courses are moddable. The developer, Xalfen, calls the project AI-assisted: “I orchestrate, specify and review, and Claude writes much of the code”, adding that they have not produced most of the codebase. In English (AI-translated, per the developer) and French. Free on itch.io.
How it was built
Partially verifiedIn a post on r/aigamedev (24 Oct 2026, UTC) the developer writes: “I'd like to be upfront that the project is AI-assisted … I orchestrate, specify and review, and Claude writes much of the code. Each feature/PR/iteration goes through a strict loop of incremental reviews depending on the sensitivity of the ticket”, with content validated through playthrough and testing loops. The developer adds that they set up a small CI/CD pipeline to test and validate the code produced and “actually learned a lot (even though I haven't produced most of the codebase).” The post names Claude without saying which Claude product or model was used.

TypeScript with Electron and React, which the developer chose because web development is what they know best. Per the developer's race-engine blog post, the simulation is a separate TypeScript package with no Node, Electron or React dependencies that reads neither the clock nor Math.random, so it runs the same in tests, a command-line tool and the app; it advances in five-second ticks, and every engine model is versioned so a save made under other rules is refused. The developer calibrates the simulation statistically against real race outcomes. The rival teams are run by the engine's shared, rule-bound decision logic (the same for every team), not by a language model. The developer's Reddit post says the English text is AI-translated.

Verification notes: AI use from the developer's post by u/Xalfenouille on r/aigamedev (24 Oct 2026, 13:06 UTC), read from the Arctic Shift Reddit archive on 8 Nov 2026 (score 1, no comments archived; observed, not a metric); the post links the itch.io page and bordure-game.com. Features from the post, the itch.io page and the official site's home, features and race-engine pages, re-read on 8 Nov 2026. itch.io: published 16 Oct 2026, status In development, last updated 2 Nov 2026; files Bordure-0.1.1-real-2026 for macOS (arm64, x64) and Windows (x64); languages English and French; AI disclosure AI Assisted, Code, Graphics; no rating or download count shown. The developer calls the project AI-assisted; we file it as vibe-coded because the same post says Claude writes much of the code and that the developer has not produced most of the codebase. No share is stated, so none is recorded. The Graphics disclosure is not explained. Developer: itch.io account Xalfen, Reddit account Xalfenouille; no name, team size or location is stated (“a solo, offline desktop game” in the post describes how it is played). The developer compares the approach with Football Manager and Out of the Park Baseball rather than Pro Cycling Manager; no names or assets from those games are used. The official site says no version is available to download yet, while itch.io offers alpha builds; see the conflict on the profile. The builds were not downloaded or played.
