Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Spark Mail

  • Several sync features route mail metadata and, for some features, credentials through Readdle servers, which is a materially different trust model from a local-only IMAP client.
  • It is a client over accounts you still pay for elsewhere, so the total cost is Spark plus whatever Gmail, Outlook or Fastmail plan you already hold.
  • The free tier lacks AI Copilot and summaries, so the features it is best known for sit behind the paid plan.
  • Team features are basic next to dedicated shared-inbox tools like Front or Help Scout, so a support team scaling past a few agents will likely outgrow it.
  • Windows and Android versions have historically lagged the macOS and iOS apps in feature parity.

tldraw

  • Production SDK use requires a license key; the dual licensing model means open-source development is free but commercial deployments are not
  • Limited ecosystem of community plugins; third-party extensibility less mature than some competitors
  • Multiplayer functionality requires custom backend implementation; real-time sync is not fully managed by tldraw
  • Mobile touch experience is functional but less optimised than desktop; precision drawing on tablets is challenging
