Import a save
Every system you have ever warped to, decoded from your No Man's Sky save. Nothing leaves your browser until you chart it.
Drop your save heresave.hg, a save-editor .json, or every file from a Game Pass wgs folder
Steam: %APPDATA%\HelloGames\NMS\st_…\save.hg. GOG: …\NMS\DefaultUser\. Game Pass: %LOCALAPPDATA%\Packages\HelloGames.NoMansSky_bs190hzg1sesy\SystemAppData\wgs\, choose that whole folder and the save blobs are found automatically. Several saves merge into one atlas.
Include other galaxiesEverything outside the galaxy you are viewing
Import your discoveriesNamed fauna, flora, minerals and bases
Credit
Stamped on every system charted below and shown on its card. Your gamertag is read from the save; add your civilization and it gets its own label on the map.

Quick chart
Add screenshots and Starweaver reads what it can. Anything it can't read becomes your next step below. Nothing leaves your phone until you tap Chart.
Best screenshots to take
Signal booster or the location readout with the galactic coordinates (four groups like 0C30:007E:025A:00EE). This pins down which system it is. Without it, type the 12 portal glyphs from your Discoveries page instead.
Galaxy map with your system selected, showing lifeform, economy, wealth and conflict.
Each planet's Discoveries page (or the scan from orbit) showing weather, flora, fauna and sentinels. One planet per screenshot.
Take them full screen and wait for the text to finish fading in. Don't crop, zoom or snap mid-animation. Sharp, steady text reads best.
On Xbox: open the Xbox app on your phone, go to Captures, and save the screenshots to your phone. PlayStation: share captures to your phone from the PS App.
The reader works on text only, entirely on your device. Star colour, planet names and the system name usually need typing in; they're listed below as your next step.

How missions work
Every gap in the atlas is a mission. Warp in with the address, then chart what you find: name the system (upload or rename it in-game, or report the name you see), set its star colour, or survey its planets. You fill the gap under your own name, and the original charter's record is never overwritten. Missions close by themselves once they're done.

About
Every No Man's Sky system has a fixed address, so one explorer's glyphs are valid for everyone. Starweaver plots those addresses on the real 4096 × 256 × 4096 region grid (4.29 billion regions, 400 ly each). Star type, faction and density are colour layers; tap any star for its address and planets, then open the system to see it as an orrery.
The save file holds a system's address, visits, bases and uploaded names, but not its star colour, planets, flora, fauna or sentinels: the game generates those from a seed when you arrive. Whoever charted a system fills those in from the edit button on its card, and the percentage on the card shows how complete the record is.
Every star on this map is a real system, charted by an explorer by hand or imported from a save, and credited to them. The core glow, nebulae and background stars are decoration, not data.
Import reads save.hg directly in your browser: it decompresses the game's LZ4 blocks, reverses the key hashing the game applies, and pulls every visited system, teleporter, base and named discovery. Nothing is uploaded until you tap Chart.
