Sifr is a cloud-native AI development platform. Your agents run in the cloud — persistent, autonomous, accessible from any device.
Not an app builder. Not a code playground. A complete development environment where AI agents work asynchronously on your real codebases.
We’re in the age of AI writing 95% of code. This changes what "development" means.
The bottleneck has moved. It’s no longer typing speed or syntax knowledge. It’s:
None of these require a keyboard. They require intent and judgment.
The old objection: "You can’t code on a phone."
But if AI writes the code, you don’t need to type. Sifr’s agents run in the cloud — independently of your device. You just need to:
Sifr isn’t "Cursor but on your phone." It’s built for a world where development is cloud-native, agents work autonomously, and you’re in control from any device.
A cloud-native AI development platform for your real projects.
Traditional AI coding tools tie your agent to your device. Close the app, the agent stops. Switch devices, you lose context. Sifr is different.
Start a refactoring task on your phone before a meeting. Your agent continues for 2 hours in the cloud. After the meeting, open Sifr on your laptop — everything is done, ready for review.
You:
"Add rate limiting to the /api/users endpoint"
Sifr AI:
→ Reads your codebase
→ Plans the implementation
→ Writes the code
→ Shows you exactly what changed
→ Waits for your approval
→ Commits and pushes when you say go
The key differentiator. You control how much freedom AI has.
Start a task, close the app, return to completed work.
Deploy to production from your phone. Securely.
Read files, write code, run commands, manage git — all through natural language.
Not a simulation. Real git operations on real repositories.
Full control over your codebase.
Run any command in your project.
Persistent cloud environments accessible from any device. No local setup required.
Multiple models from leading vendors. Pick the right AI for the task, or let Sifr auto-route. Powered by OpenRouter.
Pay for compute, not seats. See exactly what you're spending.
Your work is always saved.
AI remembers your project context.
Understanding where Sifr fits in the AI coding landscape.
They’re powerful but desktop-only. Close the app, the agent stops.
Sifr advantage: Cloud-native agents that run in background + any-device access
They generate new apps from scratch. We work on your existing codebases.
Sifr advantage: Connect GitHub, work on real repos, push real changes
They offer cloud workspaces but lack autonomous AI agents and mobile-native UX.
Sifr advantage: True background agent execution + cross-device continuity
They talk about code. Sifr executes in persistent cloud sandboxes with real git.
Sifr advantage: Persistent workspaces + full git workflow from any device
Sifr (صفر)
Arabic for "zero" — the origin of the word "cipher" and the concept of zero in mathematics. The concept of zero as a number originated in the Islamic Golden Age, revolutionizing mathematics and making modern computing possible.
From zero, everything is built. From nothing, Sifr creates working software.
Jabr (جبر)
Our internal AI harness layer. The word is the root of "algebra" — it means "completion" or "restoration."
Jabr takes incomplete intent and completes it into working code.
