Mathalama Talk

Mathalama Talk is a modern, secure, and fast platform for instant anonymous communication.

The service lets users find conversation partners based on gender and common interests in a fraction of a second. After a successful match, users can chat in private rooms or start a real-time voice call. All activity is completely private and requires no registration, email, or phone numbers. A session is created automatically based on a temporary device identifier.

Quick Start

1. Prepare Environment

Clone the repository and create your local configuration file:

cp .env.example .env

2. Start Infrastructure

Run the database, message broker, and routing infrastructure (Postgres, Redis, NATS, coturn):

# Using make utility:
make up-infra

# Or directly with Docker Compose:
docker compose up -d postgres redis nats coturn

3. Run Database Migrations

Apply schemas to Postgres databases:

# Using make utility:
make migrate

# Or directly with Docker Compose:
docker compose run --rm migrate-user
docker compose run --rm migrate-chat
docker compose run --rm migrate-moderation

4. Start Application Services

Build and start all backend services and the frontend client:

# Using make utility:
make up-services

# Or directly with Docker Compose:
docker compose up -d api-gateway user-service matchmaking-service chat-service moderation-service notification-service web

The web application will be accessible at: http://localhost:3002 (mapped to port 3000 inside the container).
