CogNote vs OPS

CogNote is an open-source studio management suite for private music teachers, combining lesson scheduling, attendance, family communication, student progress tracking, quizzes, and flashcards. Teachers can schedule recurring weekly lessons and record attendance with one tap; cancellation windows, banked credits, and credit expiry are configurable studio settings. Families can use a private link to see schedules, practice links, and notes without logging in, and teachers can email lesson notes. Progress views include skill radar charts, trend lines, attendance, and per-note quiz analytics. Students can start practice from a link without an account, using note and symbol quizzes with instant feedback or SM-2 spaced-repetition flashcards. Notation appears on a staff with clefs, key signatures, and more than 40 musical symbols. CogNote is MIT-licensed, supports data export, and can be self-hosted. Hosted Free has soft caps of five active students, five practice lessons, and five sheet music items; Hosted Pro costs $5 a month and includes a 30-day trial for new accounts. Self-hosting is free but requires running the stack, including Docker or Supabase, email, and backups.

OPS is a management platform for orchestras, bands, and music schools, bringing scores, member records, instrument inventory, accounting, and documents together. Its score library uses OCR to identify scanned scores and create a separate PDF for each instrument part. Member management supports custom fields and groups, bulk imports and exports, and optional user accounts. Instrument records can include loan contracts, repairs and maintenance, QR labels, photos, and waiting lists. The music school module handles enrolments, courses, attendance, grades, report cards, and a parent portal. Accounting follows the French Plan Comptable Général for associations and includes FEC export. Setlists can be shared with a public link or embedded on a website; ensembles can cross-share scores through the Mediathek. OPS Scores is an iPad app with Apple Pencil annotation, offline access, and Bluetooth page-turn pedal support. OPS Mobile for iPhone supports QR scanning, score browsing, inventory and loan management, member lookup, and an accounting overview. The maker says data is hosted on OVH servers in Strasbourg, stays in Europe, and is GDPR-compliant. Events, calendars, and in-product communication are marked as coming soon.
