Isolated sessions per instance, an event queue so the monitor is never blocked and retries on alert delivery.

Operational results

24/7 monitoring with configurable per-contact alerts.
Multi-session for teams managing many numbers or groups.
Integration with our bots service (the same messaging logic we use in custom projects).

Key features

Multi-session monitoring

Support for multiple simultaneous instances using Puppeteer, ideal for handling tens or hundreds of contacts concurrently.

Smart alerts

Integration with Telegram and Discord to receive instant, configurable notifications based on schedule or connection patterns.

History & statistics

Detailed session logging, activity charts and per-contact metrics for long-term analysis.

Granular control

Filters, groups, roles and differentiated permissions to organise and limit access to information.

Security & performance

VPS deployment with Nginx, SSL certificates, strict CSP, centralised logs and automatic backups.

Constant updates

Active development with a public roadmap: interface improvements, new integrations and continuous optimisations.

Technical architecture

Frontend: Next.js with a responsive interface and optimised UX.
Backend: Node.js with queues and workers for high concurrency.
Database: PostgreSQL with the Prisma ORM.
Automation: Puppeteer with persistent sessions.
Infrastructure: Nginx as a reverse proxy, Docker deployment and CI/CD pipelines.

Guaranteed compatibility

The system is designed to adapt to changes in WhatsApp Web's interface and behaviour, with continuous reviews and patches that ensure 24/7 availability.

Access

You can access the app at rovidev.com/wa-tracker and try the latest implemented features. The roadmap includes new metrics, data export and compatibility with more messaging platforms.

The service that fits this case

If you need custom bots and messaging with the same approach (clear scope, milestone deliveries and a no-commitment quote), this is the service page that fits.
