Pros and cons
Pros
Pricing
- Free tierYes
- LicenceMIT
- Self-hostYes, source is public
- Public price listNot published
Langflow does not publish a web price list. For consumer apps that usually means pricing appears inside the product; for enterprise tools it means talking to sales. Why we do this
Visit www.langflow.orgTrends
Price points are recorded when a price moves, not on a schedule, so a flat run means the price held. Release cadence comes from GitHub releases. A series appears only once we have watched it for long enough to have more than one observation.
