Welcome to Relay

Relay is a browser-based research workspace where scientists can view, analyze, and collaborate on their data. It supports images, video, electrophysiology recordings, tabular data, and more — unifying data storage, multi-modal visualization, AI-powered analysis, pipeline building, and shareable results into one platform.

Quickstart

Get up and running in minutes.

Supported File Types

OME-TIFF, Zarr, DICOM, NWB, FITS, and 30+ more formats.

AI Agent

Analyze images, run models, and build pipelines with natural language.

Models

SAM3, DeepLabCut, Suite2p, SpikeInterface, PlantCV, and SExtractor.

What makes Relay different

Unlike most web-based scientific viewers that rely on server-side rendering, Relay decodes and renders images entirely in the browser using WebAssembly. TIFFs, OME-TIFFs, CZI, ND2, LIF, and 95%+ of scientific image formats open instantly — no BioFormats server, no conversion step, no waiting.
No more switching between tools. View images, run AI models, annotate results, and share findings — all in one browser tab.
Split your workspace into up to 6 independent panes. Each pane has isolated viewport state — zoom, pan, channel adjustments, and annotations are all per-pane.
Use natural language to segment cells, track animal pose, sort spikes, analyze calcium imaging, and more. The AI agent can also write and run custom Python code in a sandboxed environment.
Relay ships with prebuilt models like SAM3, DeepLabCut, and Cellpose — but you can also add any model from a GitHub repository. Just paste a link on the Models tab and Relay builds it for you.
Relay Drive gives you managed cloud storage with uploads up to 50 GB. Connect Google Drive or bring your own S3/GCS/Azure bucket.
Browse and mount datasets from DANDI, IDR, Allen Brain Atlas, and AWS Open Data directly into your viewer.
