Interval | Build internal tools with just backend code
Interval supercharges your backend code with UIs, auth, audit logs, and more, leaving more time to focus on writing the code that matters.
Categories:
Interval is a platform that enables developers to build complete internal tools and web apps using only backend code in Node.js or Python, automatically generating the frontend UI.
🚀 Overview
Interval revolutionizes internal tool development by allowing backend developers to create full-featured web applications without writing any frontend code. Using simple SDK calls integrated into your existing Node.js or Python codebase, Interval generates responsive UIs, handles authentication, validation, and networking automatically.
It solves the problem of time-consuming internal tooling that requires dual frontend-backend expertise, enabling teams to ship secure, shareable apps quickly while keeping everything in code for version control and maintainability.
Built for backend engineers, engineering teams, and startups who prefer coding over no-code builders. The founder, Alex Arena, created it because "if you love writing code but hate building UIs, you'll love building with Interval."
✨ Key Features
- 100% Code-Driven Tools (what it does: UIs from backend SDK calls; why: keeps everything in your repo, uses native lang features like async/await, types)
- Full Component Library (inputs, tables, forms, pickers; one-line complex UIs with auto-validation)
- Automatic Network & States (no APIs needed; loading, errors, MFA for actions handled)
- Notifications & Scheduling (Slack/email alerts, cron jobs with prompts)
- Optional: Self-infra runs, audit logs, environments
🛠 Tech Stack
- SDKs: Node.js/TypeScript, Python
- UI: Browser-rendered, auto-generated (responsive/accessibile)
- Backend: Interval hosted platform
- Auth: Built-in MFA, security
- Hosting: interval.com (cloud, part of Meter)
