Insight Developer Portal

The Insight developer portal is tuvl's browser-based management UI. It is automatically served when you run tuvl dev and gives you a live view into everything your project contains — workflows, models, datasources, AI models, vector indexes, users, and more — without writing a single line of code.

Accessing the portal

Start the dev server from your project directory:

cd my-project/
tuvl dev

tuvl prints the portal URL and a one-time security key:

╭─ tuvl dev ───────────────────────────────────────────────────────────╮
│ Starting tuvl engine in dev mode on port 8000.                       │
│ Project: /home/user/my-project                                       │
│                                                                      │
│ Open http://127.0.0.1:8000/insight/ and the security key is stored  │
│ in .tuvl/.dev-session (run tuvl dev --show-key to print it).         │
╰──────────────────────────────────────────────────────────────────────╯

tuvl also opens the portal in your default browser automatically. Paste the security key from .tuvl/.dev-session when prompted.

Print the key directly

Use tuvl dev --show-key to print the key in the terminal output. The default is to store it silently so shell history recordings cannot capture it.

Dev mode only

The Insight portal is only available when TUVL_DEV_MODE=true. It is never served in production builds to eliminate any attack surface.

Portal navigation

The sidebar contains all top-level sections:

Section Description
Workflows View, edit, and visualise your workflow YAML files
Models Inspect and edit ModelDefinition files
Datasources Manage PostgreSQL connection configs
AI Models Configure LLM agents (Ollama, OpenAI, Anthropic, …)
Embeddings Define embedding model configs for vector search
Collections Manage pgvector collections for RAG
IAM Users, roles, and scope management
Federation OAuth2 / OIDC provider setup
API Docs Live Swagger UI for your project's REST endpoints
Spectrum Workflow test runner and visual debugger
Settings Redis, telemetry, and LLM Judge configuration

How it works

The portal communicates with the tuvl engine over gRPC-Web (via DevService) for all file operations and dev-only queries. The DevService exposes endpoints for listing files, reading/writing YAML configs, running single-node Lens probes, and streaming full workflow executions through Spectrum.

Regular workflow execution and auth endpoints use the standard REST API at /api/*.

Requirements

Requirement Version
tuvl ≥ 25.4
tuvl-insight Included with pip install tuvl[standard]
Browser Any modern Chromium, Firefox, or Safari

tuvl_insight package

The portal is shipped as the separate tuvl_insight package. It is bundled when you install with the standard extra: pip install tuvl[standard]. If you install the bare tuvl package, the portal will not be available.
