Local Development

Quick Start

./scripts/dev-runner.sh --restart   # First time / full rebuild
./scripts/dev-runner.sh --start     # Daily start (no rebuild)
./scripts/dev-runner.sh --stop      # Stop everything
./scripts/dev-runner.sh --verify    # Check status

Modes

Mode	Command	Frontend	Use When
Standard	--restart	localhost:5174	Frontend work, full-stack
BE-only	--be-only-restart	localhost:5173	Backend-focused, faster rebuilds
Platform (EM)	PLATFORM_ENABLED=true ./scripts/dev-runner.sh --restart	localhost:9100	Opik-team only: run Opik connected to the Comet Platform

Platform (EM) mode — Opik-team only

PLATFORM_ENABLED=true runs the Comet EM/Platform stack (comet-backend + comet-react, auto-detected sibling checkouts) alongside Opik behind a single-origin nginx proxy, with Opik in comet mode authenticating/resolving workspaces via comet-backend. Off by default — Standard/BE-only dev is unaffected. comet-backend builds under a detected JDK 17/21; Opik still uses JDK 25.

PLATFORM_ENABLED=true ./scripts/dev-runner.sh --restart   # then also --start/--stop/--verify
# Integrated UI:  http://localhost:9100        (comet-react / Platform)
#                 http://localhost:9100/opik   (Opik, comet mode)

Env vars (COMET_BACKEND_PATH, COMET_REACT_PATH, PLATFORM_JAVA_HOME, PLATFORM_*_PORT) and --platform-build are documented in ./scripts/dev-runner.sh --help.

URLs

• Frontend: localhost:5174 (standard) / localhost:5173 (BE-only)
• Backend API: localhost:8080
• Health: http://localhost:8080/health-check?name=all

Build Commands

./scripts/dev-runner.sh --build-be   # Backend only
./scripts/dev-runner.sh --build-fe   # Frontend only
./scripts/dev-runner.sh --lint-be    # Spotless
./scripts/dev-runner.sh --lint-fe    # ESLint
./scripts/dev-runner.sh --migrate    # DB migrations

Logs

tail -f /tmp/opik-backend.log        # Backend
tail -f /tmp/opik-frontend.log       # Frontend (standard)
docker logs -f opik-frontend-1       # Frontend (BE-only)

SDK Config

export OPIK_URL_OVERRIDE='http://localhost:8080'
export OPIK_WORKSPACE='default'

Troubleshooting

Won't start:

./scripts/dev-runner.sh --verify
lsof -i :8080                        # Port conflict?
./scripts/dev-runner.sh --stop && ./scripts/dev-runner.sh --restart

Build fails:

cd apps/opik-backend && mvn clean install -DskipTests
cd apps/opik-frontend && rm -rf node_modules && npm install

Database issues:

./scripts/dev-runner.sh --stop
./opik.sh --clean                    # WARNING: deletes data
./scripts/dev-runner.sh --restart
