With Q3 in full swing, we've shipped product updates to speed up your development: Side‑by‑side Playground testing, real‑time alerts (Webhooks & Slack) for prompt changes, usage alerts on Langfuse Cloud, and one‑click remote experiments for non‑technical teammates.

Q3 Roadmap Highlights & Townhall

Earlier this month, we held our Q3 planning and a community Townhall. Here are some of the highlights we will be working on in Q3:

• Agent observability: unified agent graphs, richer tracing (tool‑call span types), built‑in agent evaluations across conversation/response/turn/trajectory.
• Evaluation: rule‑based evaluators; LLM‑as‑judge at multiple levels with debugging & cost tracking; comparison dashboards (correlation, confusion matrix, overlap); SDK abstraction for dataset runs.
• Data, prompts & platform: multimodal support for Datasets & Playground; I/O schema validation; tool/function support in Prompt Experiments; platform webhooks; in‑app routing.

Playground Side-by-Side Comparison

Open multiple chat windows in parallel to compare prompts, models, variable inputs, or tools, and restore the test state.

This enables faster A/B testing, fewer open tabs, and shorter feedback cycles.

Slack & Webhooks for Prompt Changes

We added Webhooks and a Slack integration to get real-time notifications for new prompt versions, changes to deployment labels or tags, and other edits.

We’re expanding webhook triggers to cover more Langfuse events soon.

Trigger Remote Custom Experiments

You can now trigger external Dataset Runs directly from the Langfuse UI. This feature enables non-technical users to run tests on Datasets without requiring code changes or manual setup.

New docs and integration pages

We reorganized our docs and integration guides to make discovery easier across observability, prompts, and evals.

More July Releases

• Usage Alerts (Cloud): Set a threshold for monthly events; we'll notify you once per billing cycle when you cross it.
• Sessions in the Annotation Queue: Integrate Sessions into your human annotation workflow.
• n8n Node: Fetch Prompts from Langfuse Prompt Management into your n8n workflow.
• Prompt Full-Text Search: Search through all your prompts to help find and organize large prompt collections.
• LiveKit Integration: Trace your LiveKit agents to see latencies, costs and use it together with other Langfuse features.
