Is there a ChessReps alternative that covers more than openings?

Yes — Mainline. It drills opening repertoires the same way, then analyzes your real games with Stockfish at depth ≥20 and drills the middlegame, endgame, and tactical weaknesses costing you rating points. ChessReps stops at the opening; Mainline keeps going.

What's the difference between ChessReps and Mainline?

ChessReps is a spaced-repetition opening-repertoire trainer built on pre-made and community courses. Mainline trains openings too, but it's built from your own chess.com and Lichess games — it finds the exact mistakes losing you games and drills those across the whole game, every line engine-verified.

Mainline vs ChessReps — the same opening drilling, plus the rest of your game

ChessReps is a strong opening-repertoire trainer built on spaced repetition.

If you've outgrown "just openings," Mainline is the next step.

What ChessReps does well

ChessReps is a focused, well-built opening trainer. Its spaced-repetition engine is genuinely good at burning a repertoire into memory, and its large community library means there's a course for almost any opening you want to learn. If your single goal is to memorize opening lines, it does that job cleanly.

Where Mainline goes further

Mainline trains the same opening repertoires, but it doesn't stop at move ten. It imports your real games, prices every mistake in rating points with Stockfish, and builds drills from your own blunders — in the middlegame and endgame, not just the opening. Every line you drill is verified at depth ≥20, so you're never memorizing a dubious community course.
