A free TFT economy and leveling helper for Windows

tft-synapse is a small always-on-top window for Teamfight Tactics. It reads your gold, level and HP from the running game and tells you when to save, level up or roll down, what level to aim for, and when the next augment, carousel and PvE round come.

macOS and Linux builds: Releases

Early version. Riot's local game API does not send your board, shop, items or augment choices, so the economy, stage and lobby advice work in a real game, and the augment, shop, board and item panels stay empty for now.

How it works

Diagram: every half second tft-synapse asks the running TFT game for its state through Riot's local Live Client Data API at 127.0.0.1:2999. It reads gold, level, HP, the stage estimated from game time, and the lobby's names, HP and levels. Board, bench, shop, items and augment choices are not in the API and stay empty. The window shows economy advice, the target level with the next augment, carousel and PvE rounds, and each lobby player's HP. — No login, no API key: it only reads what the game serves on your own PC.

What you get in a real game

Works Economy

Save, level up or roll down, with the reason: interest thresholds, low HP, gold at the cap.

Works Stage awareness

Target level for the stage and the next augment, carousel and PvE rounds.

Works Lobby

Every player's HP and a threat level.

Empty Augments, shop, board, items

The advisors exist in the code, but the game API does not send this data.

Example advice

Real output of the advisor code for three game states (cargo run -p tft-synapse-advisor --example advise):

Stage 3-2  gold 52  HP 64  level 6
  Economy: LEVEL UP. Gold at interest cap (52); leveling up from 6 improves shop odds
  Target level 6. Augment this round: pick carefully
  In 3 round(s): PvE: Raptors

Stage 4-5  gold 34  HP 22  level 7
  Economy: ROLL DOWN. Low HP (22): roll to find upgrades urgently
  Target level 8 (behind). Roll down: you're behind on levels
  In 6 round(s): Stage 5 carousel

Use it in 3 steps

Start a TFT game and wait until you are in the match.
Run tft-synapse.exe. Windows may say "unknown publisher" because it is unsigned: click More info, then Run anyway.
Keep it beside or over the game. F9 lets clicks pass through; Alt+Tab back and press F9 again to undo. Opacity is under Overlay Settings.

Start it after the game has loaded: if no game answers at startup, it uses a rough screen-pixel reader for the whole session.
