Tech Stack

Want to contribute?

All these technologies work together in our monorepo structure. Check out the Project Structure page to understand how everything is organized.

Our platform is powered by a modern, high-performance technology stack split into cohesive layers across our monorepo architecture.

Frontend

The user-facing interfaces and UI packages prioritize responsiveness, design aesthetics, and type safety.

Powering the landing web, customer dashboard, admin portal, and documentation site.

Providing utility-first premium styling tokens across all frontend applications.

Headless component primitives driving our unified design system in the @reloop/ui package.

Client-side data fetching, caching, and optimistic mutations.

The decoupled backend layer runs on a high-throughput runtime and handles heavy outbound routing workloads.

Fast, type-safe backend framework for all microservices.

Ensuring strict type contracts between microservices and frontend clients.

Lua-governed modern outbound ESMTP mail server engine.

We utilize separate database technologies matching specific transactional, caching, and analytical requirements.

Caching, session states, and asynchronous background worker queues.

Columnar analytics store tracking delivery logs, bounces, and click events.

Our DevOps and tooling pipelines ensure extremely fast builds, local setups, and deployments.

Modern JS runtime environment, script runner, and package manager.

Parallel task executor and build system scheduler for the monorepo.

Containerized stack for local development services and databases.

Decentralized asynchronous real-time event broker.

Object storage holding campaign assets, organization logos, and attachments.

Tooling enforcing consistency and code quality boundaries across team workflows.

Ultra-fast code formatter, linter, and import sorter.

Pre-commit git hooks enforcing code style and commit consistency.
