A terminal UI for querying and comparing cloud pricing across providers, built with Rust and Ratatui.

⚠️ Beta: each query returns up to 150 results, sorted by min price ascending.

Two Ways to Query

CloudCent works in both directions — start from what you know, find what you need:

• Spec → Cost: Know your requirements? Describe the instance type, region, storage class, or any spec, and CloudCent returns the matching price. Filter by vCPU count, memory, storage tier, and more.

• Cost → Spec: Have a budget? Set a price ceiling or floor and discover which products and configurations fit within it. Use >, <, >=, <= operators to explore what's available at your price point.

Features

• Multi-cloud pricing search — query pricing data across AWS, GCP, Azure and more from a single interface

• Smart suggestions — fuzzy matching and semantic aliases (e.g. type "compute" to find EC2, Compute Engine, VMs)

• Command builder — structured form with product, region, attribute, and price filter fields with autocomplete

• Raw command mode — type queries directly for power users (product region attrs )

• Attribute filtering — drill into instance types, storage classes, vCPU counts, etc.

• Price operators — filter results with >, <, >=, <=

• Query history — browse past queries, preview cached results, and re-run with one keystroke

• Local caching — SQLite-backed cache for pricing data and metadata (3-day TTL)

• Settings view — view your CLI ID, API key, and config path

• Cross-platform — runs on macOS, Linux, and Windows (x64 and ARM64)

Installation

npm (recommended)

npm install -g @cloudcent/cli

Shell script (macOS / Linux)

curl -fsSL https://raw.githubusercontent.com/OverloadBlitz/cloudcent-cli/main/install.sh | bash

PowerShell (Windows)

Quick Start

cloudcent

On first launch you'll be prompted to authenticate via browser. This sets up a free API key stored at ~/.cloudcent/config.yaml.

Supported Providers & Pricing Models

Provider Services

AWS EC2, ECS, EKS, S3, RDS, ElastiCache, EMR, SageMaker, Bedrock, Direct Connect, Data Transfer, Backup

GCP Compute Engine, Cloud Storage, Cloud SQL, GKE, Memorystore, Vertex AI, Big Data, Data Transfer

Azure Virtual Machines, AKS, Container, Storage, SQL Database, Redis, Backup, Machine Learning, OpenAI, ExpressRoute, Bandwidth, Big Data

OCI Compute, Object Storage, Database Instance, Cache, Backup, FastConnect, Data Transfer, Generative AI

Pricing models vary by provider — OnDemand, Reserved/Committed, Spot/Preemptible, and token-based (for AI APIs).mptible, and token-based (for AI APIs).

Beta limitation: each query returns up to 150 results, sorted by min price ascending.

Available products and pricing models are fetched dynamically from the API and may expand over time.

Configuration

Config is stored at ~/.cloudcent/config.yaml with permissions set to 600 on Unix.

Data files:

• ~/.cloudcent/metadata.json.gz — compressed pricing metadata

• ~/.cloudcent/cloudcent.db — SQLite database (history, cache)

Contributing

Contributions are welcome. Here's how to get started:

• Fork the repo and create a branch from main

• Build the project locally: cargo build

• Run in dev mode: cargo run

• Make your changes — keep them focused and minimal

• Ensure the code compiles cleanly: cargo check && cargo clippy

• Open a pull request with a clear description of what you changed and why
