Langflow
Open Source (Self-Hosted) — Free Free (MIT license)
Langflow Cloud Free Tier — Free Free
Langflow Cloud Paid — From about $25/month Monthly
Native support for 50+ languages, including low-resource languages, at no extra translation cost
Simple one-line script-tag install, with dedicated guides/plugins for WordPress, Shopify, Wix, and Squarespace

FAQ-first design answers strictly from the uploaded knowledge base, limiting off-topic or hallucinated responses
Transparent published pricing with no hidden or per-seat surprise fees
Cons
No independent user reviews yet on third-party sites like Capterra, making real-world reliability hard to verify
Query and FAQ-entry limits on the Starter and Pro plans may require an upgrade for higher-traffic sites
Company legal name, headquarters, and founding year are not publicly disclosed
Documented integrations are limited to WordPress, Shopify, Wix, Squarespace, and a generic API — no listed native Slack, Zapier, or HubSpot integrations
Langflow
Pros
Fully open source and free under the MIT license, with no forced paid tier for core functionality
Visual canvas makes RAG and agent prototyping accessible to non-expert developers
Ability to export to raw Python code bridges the gap between prototyping and production
Large and fast-growing GitHub community with over 150,000 stars
Backed by IBM's resources following the DataStax acquisition, aiding long-term maintenance
Cons
Real-world costs still come from LLM API usage, vector databases, and infrastructure, which are not included in the free software
Self-hosted deployments require managing servers, scaling, and monitoring without a managed cloud plan
Visual flows can become difficult to manage for very complex, large-scale agent architectures
Ownership changes (Logspace to DataStax to IBM) may raise questions about long-term product direction for some adopters
Langflow Cloud does not publish a detailed public pricing page beyond a reported starting price
Use Cases
