Endstep Tracker by Mickael Couzinet

Endstep Tracker automatically records the Magic: The Gathering matches you play on endstep.cc and turns them into a personal match history, all stored locally in your browser.

While you play, the extension icon shows a REC badge, and a small panel on the game page shows, between two games, the opponent's archetype, your record against it and your usual sideboarding. The toolbar popup shows the same during a match, and your session otherwise.

The dashboard opens on the deck you play most:

• At a glance: your win rate, your records on the play and on the draw, and your latest results.

• Matchups: record in matches, on the play and on the draw.

• My cards: for each card of your deck, the win rate of the games where you drew it, next to the games where it stayed in your library and the games where it was in your opening hand.

• Your sideboarding: what you bring in and take out between games is recorded, shown for each matchup and recalled between two games against the same kind of deck.

• List versions: when your main deck changes, compare the new list with the previous one, matchup by matchup.

• Match history: date, format, opponent, your deck, score, result.

• Per game: play/draw, mulligans, your opening hand, turns, final life totals, duration, and the full game log.

• Opponent cards seen, with card preview on hover, and automatic archetype recognition from endstep.cc's public metagame.

• Honest numbers: every rate shows its sample size, and nothing reads as a percentage before 5 results.

• Search the history: opponent, archetype, card seen, note.

• Notes per match, "My deck" picker, export to JSON or CSV, import, delete everything.

Everything stays on your computer. The extension never sends anything to endstep.cc, never plays for you, and has no server, account, analytics or ads. Only public game information (what you could see on screen) is recorded, and nothing is recorded while spectating.
