A free, accessible, browser-based character creator and editable sheet for Mongoose

Traveller 2022

— every roll cited, every choice logged, every character saved locally.

Description

Traveller Lifepath is a free, browser-based character creator and editable sheet for Mongoose Traveller 2022. It walks players through the full Mongoose 2022 lifepath — basics and species, characteristics, background skills, pre-career education (University, Army Academy, Marine Academy, Navy Academy), career terms with their full survival / event / commission / advancement loop, mustering-out, the post-creation skill package, and a final reviewable character sheet — without ever leaving a single browser tab. The tool offers three ways to set characteristics. Players who want the classic experience can have the site roll 2D × 6 into a pool and assign each value to whichever stat they like. Players who prefer their own physical dice can enter results manually; the site still tracks every DM, target, success/failure, and aging effect. Players who'd rather skip randomness entirely can use the included point-buy method (42-point budget, 2..12 per stat). PSI is rolled separately when psionics are enabled, and the Psion career unlocks accordingly.

The character-creation rules are implemented as a typed effects engine — TypeScript discriminated unions with exhaustive switching — so every rule lives in one place and can be tested in isolation. The project ships with around 360 automated tests covering qualification, commission, advancement, aging crises, mishaps, life events, connections, the skill cap of 3 × (INT + EDU), pre-career education, and the Mongoose 2022 errata clarifications for Vargr and the Vacc Suit skill. A full audit trail of every rolled die, every applied DM, and every player choice is captured to a roll log that updates in real time. The post-creation sheet is a fully editable Mongoose-style character record. Skills, careers, equipment, weapons, armour, augments, connections, benefits, and free-form notes can all be edited inline; values save automatically to localStorage with cross-tab synchronisation, and the sheet is print-friendly (one panel per printed page, ink-friendly styling). Every character in the local library can be exported and re-imported as JSON for backup or for handing off between players. Two visual themes are included: a light "Little Black Books" look in the spirit of Classic Traveller, and a dark "Imperial" theme — plus a System mode that follows the operating system's light/dark preference and reacts live when it changes. Theme choice is remembered between sessions. Accessibility is treated as a first-class concern. The interface meets WCAG 2.1 AA contrast requirements in both themes (verified by an axe-core audit suite that runs as part of the project's tooling), every interactive element has a visible keyboard focus indicator, icon-only buttons carry ARIA labels, and the layout includes a skip-to-content link for screen-reader users.

Other features include undo across the wizard (rewinds to the relevant picker after popping a character snapshot), URL-based debug logging (?debug=1), the Connections rule for shared PC backgrounds, an aging-crisis path with medical-debt accumulation, and an honest "unofficial fan tool" disclaimer in every place it matters. The project is open-source under the MIT License, runs entirely client-side with no backend and no account requirement, and uses privacy-friendly analytics (no cookies).
