The short version
- Only Comet ML has a free tier, so it costs nothing to try first.
- Each has a real cost: Aha! sold as eight separate products rather than one subscription, so Roadmaps, Discovery, Ideas, Whiteboards, Builder, Develop, Teamwork and Knowledge are each priced per user; Comet ML the free cloud tier caps data at 25,000 spans a month with 60 day retention
- They diverge on capability: Aha! covers Strategic roadmaps, Comet ML covers Experiment tracking.
