Usage numbers come from the production database on 23 Sep 2026 (34 accounts, 17 active in the last 30 days, 6.5 GB of files, 58 uploads and 96 assistant messages in the last 30 days, 16 streaming accounts linked, 14 social accounts linked). Prices: Netcup RS 2000/4000/8000 G12, Cloudflare R2 (storage $0.015/GB, writes $4.50 per million, reads $0.36 per million, egress free), Claude Haiku 4.5 ($1/$5 per million input/output tokens) and Sonnet 5 ($2/$10), Songstats direct licensing (EUR 0.25 / 0.20 / 0.15 per artist, minimums EUR 75 / 250 / 500, per the CEO's email of 11 Aug 2026), AWS SES ($0.10 per 1,000 emails), LiveKit Cloud (Build free up to 5,000 participant minutes, Ship $50 for 150,000 then $0.0005 a minute, Scale $500 for 1.5 million then $0.0004), the korbee.app domain and the Apple Developer account.
Social data: follower and engagement numbers come from Songstats (priced above, per artist), while audience demographics and ad results come straight from the Meta Graph API and the TikTok API through Korbee's own apps, which have no usage fees. Zernio, the per-account intermediary used until September 2026, is being replaced by this and is no longer in the model. Not included, because today it is free or unused: Coolify, Cloudflare DNS, Uptime Kuma, APNs/FCM (push notifications), ipwho.is (geolocation), Google Play ($25 once), Composio and Sentry (no keys on production), Cloudflare Stream (unused). Past a few tens of thousands of users a custom domain on R2 should be added.
