// 01.a
framework
Next.js
The React framework we reach for first. Server components, routing and edge-friendly builds out of the box.
// engineering
The stack behind RainThread.
We engineer the full stack end-to-end. From the React apps our customers click through, to the indexing pipelines, to the servers running the crawler network — every layer is built and maintained in-house.
What customers see and click.
The dashboards, configuration screens and reporting surfaces across every RainThread product.
// 01.b
ui library
React
The component model under every interface we ship. Strict mode, hooks, no legacy class components.
// 01.c
styling
Tailwind CSS
Utility-first styling so design tokens, spacing and theming stay consistent across every screen.
// 01.d
components
shadcn/ui
Component primitives owned in our own codebase — accessible, themeable, no opaque third-party design system.
Where the code actually runs.
Server-side workloads, background jobs and the desktop clients that ship with a few of our tools.
// 02.a
runtime
Node.js
Our server-side JavaScript runtime. API handlers, scheduled workers and the long-running services behind the products.
// 02.b
desktop
Electron
Desktop apps from web tech. Used where our customers need local control — local storage, native filesystem, offline mode.
Where the state lives.
Different problems want different stores. We pick the right shape for the job instead of forcing one engine to do everything.
// 03.a
relational
PostgreSQL
Our primary relational database. Every campaign, customer account and billing record lives here.
// 03.b
cache · queue
Redis
In-memory cache and job queues. Powers the hot paths and every background worker pipeline.
// 03.c
embedded
SQLite
Embedded storage inside our desktop clients. Zero-config, file-on-disk, fast for single-machine workloads.
How it all gets to production.
The networking layer, the deployment pipeline and the containers everything runs inside.
// 04.a
containers
Docker
Every service ships as a container. Same image runs locally, in CI and in production — no environment drift.
// 04.b
edge · dns
Cloudflare
Edge network, DNS, DDoS protection and CDN. Our front door to the world and the layer that absorbs the load.
// 04.c
deploys
Coolify
Self-hosted deployment platform. Lets us own the infra end to end without the lock-in of managed PaaS pricing.
How the team works.
The connective tissue between people and code — source control, code review and the daily engineering loop.
// 05.a
source control
GitHub
Source of truth for every repository. Code review, CI runs, release branches and the audit trail behind every change that ships.
