Main Sequence tools for launch and play
Three small tools with clear jobs. No account, no newsletter wall and no pretend game data. Where a number is unconfirmed, the tool says so.
- No account needed
- Local browser storage
- Source notes included

Tools are built around confirmed dates, demo progression and crew roles.
Pick the tool for the question
These are intended to remove a decision or a repetitive step, not to pad a page with fake interactivity.
Live tool
Release countdown & time zones
Tracks the listed Early Access unlock timestamp, converts it to local time and clearly separates the official date from the unofficial hour.
Saves locally
Demo progress checklist
A spoiler-light checklist from requirements and first scan through station power, Logistics I, co-op and the Slipstream Drive objective.
Interactive
Co-op crew planner
Assign logistics, production, defense and exploration across two to four captains, with a first move for each shift.
Your checklist stays on your device
The demo checklist uses browser localStorage so it works without an account or a database. We do not receive your progress.
If your browser blocks storage, the list still works for the current page visit but will not persist. The crew planner is generated on the page and is not submitted anywhere. The countdown runs entirely in the browser.
What we do not do
- No fake in-game live player counter.
- No invented build calculator based on unknown recipes.
- No account system or email gate.
- No promise that a tool matches a future patch.
