AI Gateway Alternatives
After the Acquisitions
Helicone was acquired by Mintlify. Langfuse was absorbed by ClickHouse. The AI observability market consolidated in early 2026. Here are the alternatives that are still independent and actively developed.
Side-by-side comparisons, migration guides, and feature breakdowns.
Helicone Alternatives 2026
Helicone was a popular AI gateway proxy built in Rust with request logging, cost tracking, and caching. After Mintlify acquired it in March 2026, the team was reassigned to documentation products. The platform is in maintenance mode with no new features planned.

Langfuse Alternatives 2026
Langfuse was the leading open-source LLM observability platform with 2,000+ paying customers and 26M+ SDK installs per month. ClickHouse acquired it as part of their $400M Series D at a $15B valuation. Its roadmap is now tied to database infrastructure priorities.

No acquisition risk. Curate-Me is an independent company focused entirely on AI agent governance. Your infrastructure will not be absorbed into a database or documentation company.
Governance, Not Just Observability
Helicone and Langfuse watched what happened. Curate-Me controls what happens. Cost enforcement, personal data scanning, rate limiting, model allowlists, and human approvals on every request.
