View Full Features →Yes. Agenta's core platform is open-source and can be self-hosted on your own infrastructure, which is common for teams with strict data-residency or compliance requirements. A managed cloud version is also offered, and enterprise tiers add private deployment, SSO, and advanced security controls.
Langfuse and Helicone focus primarily on tracing, analytics, and prompt management, while Agenta bundles prompt management, structured evaluations, and observability into one workflow. Agenta also emphasizes non-technical collaboration in the playground, which is less central in purely developer-focused tools.
Agenta is model- and framework-agnostic. It works with OpenAI, Anthropic, Google, Mistral, Cohere, and self-hosted open-source models, and integrates with LangChain, LlamaIndex, and LiteLLM. Its tracing is built on OpenTelemetry, so it plugs into standard observability pipelines.
It supports automated evaluators (exact match, similarity, regex, JSON validation, RAG faithfulness), LLM-as-a-judge evaluations, and human annotation workflows. Teams can run batch evaluations across multiple prompt variants and models using shared test sets and view results in comparison dashboards.
No. Product managers, domain experts, and QA can edit prompts, run test cases, and review outputs through the web UI. Engineers typically wire the application up with Agenta's SDK once, after which prompt changes can be deployed without touching application code.
AI builders and operators use Agenta to streamline their workflow.
