Is building a third-party client on someone else's platform API viable?
No-go since 2026-10-25 · ledger #68
The platform owner controls the enabler and has used that control; nothing has changed it.
Short answer
Apollo, a popular Reddit client, shut down on 30 June 2023 after Reddit's new API pricing would have cost it about $20M a year; Tweetbot and Twitterrific died the same way when Twitter cut off third-party clients in January 2023. Nothing about the apps changed. When the platform owns the enabler, it can take the market the moment you prove it.
