Local-first cost console

Every cloud bill.
One machine.
Nowhere else.

CloudBridge reads AWS, Alibaba Cloud, and DeepSeek billing into one local ledger, then draws the trends. No sign-up, no sync, no telemetry.

Features

what it does
Multi-cloud

Three providers, one place

AWS, Alibaba Cloud, and DeepSeek balance tracking in a single dashboard. Azure and GCP are coming soon.

Standard

A real ledger, FOCUS-shaped

Every source normalizes into one fact table named after FOCUS columns — the FinOps Foundation's open cost and usage specification — so credits, refunds, taxes, and fees are each labelled as themselves, and a real bill export drops in with no schema change.

Charts

Cost visualization

Monthly overview, per-service breakdown, and 30-day trends — readable at a glance.

Security

Credentials in the OS keyring

Credentials live in the OS keyring, never in the database. Your data never leaves your machine. No cloud sync, no telemetry.

Cache

Frugal with paid APIs

A billing period is re-fetched at most once every 6 hours, and Cost Explorer is asked for everything in one request per period. Force Refresh when you need it now.

Interface

Modern UI

Built with GPUI, Zed's GPU-accelerated framework. Native performance, light and dark themes.

Analytics

Cost analytics

Daily totals, averages, highs, and lows, with month-over-month comparison.

How it works

three steps
01

Download & install

Download the build for your platform and run it. No installer, no sign-up.

02

Add cloud accounts

Enter your cloud provider credentials. They go straight into your OS keyring — never into the database.

03

Visualize costs

Open the dashboard for monthly totals and trends. Each billing period is re-fetched at most once every 6 hours.

Windows x64 cloudbridge-windows-x64.exe Download
macOS arm64 cloudbridge-macos-arm64.dmg Download

Windows: SmartScreen may warn about unsigned executables. Click "More info" → "Run anyway" to proceed.

macOS: Open the disk image and drag CloudBridge to Applications. The app is ad-hoc signed but not notarized, so the first launch needs a right-click → Open. If Gatekeeper still refuses, run xattr -cr /Applications/CloudBridge.app.

Linux and Intel Macs build from source. Or browse all releases on GitHub.

FAQ

answers
Is CloudBridge free to use?
Yes! CloudBridge is completely free and open source under the MIT license. You only pay for your cloud provider's API costs (AWS Cost Explorer charges $0.01 per request; Alibaba Cloud and DeepSeek APIs are free).
How is my data secured?
Credentials live in your OS keyring (Windows Credential Manager, macOS Keychain) — never in the database. Cost data stays in a local DuckDB ledger, and nothing leaves your machine except direct API calls to your cloud providers.
Which cloud providers are supported?
AWS, Alibaba Cloud, and DeepSeek (balance tracking) are fully supported today. Azure and Google Cloud Platform support is planned — see the roadmap.
What is FOCUS, and why does it matter?
FOCUS is the FinOps Foundation's open specification for cost and usage data — one shared column vocabulary (billed cost, effective cost, charge category) across every cloud vendor. CloudBridge stores every charge in FOCUS terms, so provider quirks live in one normalization layer and a real AWS CUR or Alibaba Cloud bill export drops in with no schema change.
What IAM permissions does CloudBridge need?
CloudBridge only needs read-only billing access. For AWS, attach a policy with the four Cost Explorer read actions; for Alibaba Cloud, attach the built-in AliyunBSSReadOnlyAccess policy. Ready-to-use templates and step-by-step instructions are in docs/policies.md.
Does CloudBridge work on Linux?
Linux and Intel Macs are not published as binaries yet — both build from source with a single cargo command (see the README). Published builds cover Windows (x64) and macOS (Apple Silicon).
How often is cost data refreshed?
A billing period is re-fetched at most once every 6 hours, so paid API calls stay minimal. Refresh picks up anything stale; Force Refresh re-fetches regardless, at the cost of another paid API call.
Can I export my cost data?
A bill export channel (S3 / OSS + Parquet) is on the roadmap. For now, the ledger is a local DuckDB database that you can query directly.
