Why DynamoOps

The AWS Console reloads on every click, and the CLI makes you memorize syntax. DynamoOps puts everything you do with DynamoDB in one fast desktop window.

• Every feature is free. There are no plans, no trials, no account and no license key.
• It runs on your machine. Credentials and table data never leave it, and there is no telemetry.
• It works at work too. Companies, including for-profit ones, can use it internally.

Download

Get the latest installers from the releases page.

System	File
macOS · Apple Silicon (M1 or newer)	DynamoOps-<version>-arm64.dmg
macOS · Intel	DynamoOps-<version>-x64.dmg
Windows 10/11 · installer	DynamoOps-Setup-<version>.exe
Windows 10/11 · portable, no install	DynamoOps-<version>-portable.exe

Every release includes SHA256SUMS.txt so you can verify the files you downloaded.

Note

The builds are not signed with Apple or Microsoft certificates yet.

• macOS: on first launch, macOS says it cannot verify the app. Click Done, open System Settings › Privacy & Security, click Open Anyway next to the DynamoOps message and confirm. You only do this once per version.
• Windows: if SmartScreen warns you, click More info and then Run anyway.

Features

Connect to anything AWS CLI profiles, saved profiles with recent connections, Assume Role with role history, AWS SSO (IAM Identity Center) sign-in in the browser, and custom endpoints for DynamoDB Local and LocalStack. Each connection can carry an environment tag (dev, qa, staging, prod, local). Query without the docs open Scan with filter expressions, Query by key on the table or any GSI/LSI, and a PartiQL editor with syntax highlighting, context-aware autocomplete, templates built from your schema, formatting and a confirmation before writes. Edit data in place Double-click a cell to edit it, or open the full JSON editor. Insert, clone and bulk delete items, use per-table insert templates, and restore any previous version from the item history with a field-by-field diff.

See what every operation costs The read and write capacity DynamoDB reports for each operation, a running session total per table and a cost alert. Watch changes live A real-time DynamoDB Streams feed with INSERT, MODIFY and REMOVE events and attribute-level change summaries. Ship infrastructure and code Export a table as CloudFormation, Terraform or Pulumi. Generate a snippet for the current query, or a complete data-access project (entities, repositories, services) in TypeScript, Python, Java, C#, Go, Ruby, PHP or AWS CLI scripts. And the rest Multiple tables in tabs, table/JSON/chart views with a partition heatmap, JSON/CSV/Excel import, JSON/CSV export, a table dashboard with CloudWatch metrics, keyboard shortcuts, a collapsible sidebar, and dark and light themes.

Good places to start:

• Quick start
• Connecting to DynamoDB
• Keyboard shortcuts
• Security and privacy

Keyboard shortcuts

Cmd on macOS, Ctrl on Windows.

Shortcut	Action
Cmd+Enter	Run the current Scan, Query or SQL
Cmd+R	Refresh the current query
Cmd+W	Close the active tab
Cmd+[ / Cmd+]	Previous / next tab
Cmd+K	Search tables in the sidebar
Cmd+B	Collapse or expand the sidebar
Cmd+F	Filter the loaded items
Esc	Close the open dialog

Build from source

You need Node.js 18+, npm and Git.

git clone https://github.com/renatoasterio/DynamoOps.git
cd DynamoOps
npm install

npm run electron   # desktop app
npm run dev        # browser only, at http://localhost:3457

Tests and lint must pass before a pull request is merged:

npm test
npm run lint

Build installers locally (output in dist/):

npm run build:prod:mac            # macOS Apple Silicon (.dmg)
npm run build:prod:mac:universal  # macOS Universal
npm run build:prod:win            # Windows x64 (installer + portable)

Tip

Building the Windows installer on an Apple Silicon Mac needs Rosetta, because electron-builder's Windows tools are Intel binaries. The release workflow builds both platforms on native GitHub runners, so you rarely need this.

Releases

Releases are built by .github/workflows/release.yml. main is protected, so the version bump goes through a pull request and the tag is pushed after the merge:

# 1. Bump the version in a pull request
git switch -c release/3.0.1
npm version 3.0.1 --no-git-tag-version
git commit -am "chore(release): 3.0.1"
git push -u origin release/3.0.1      # open the PR, review and merge it

# 2. Tag the merged commit on main
git switch main && git pull
git tag v3.0.1
git push origin v3.0.1

Pushing the tag starts the workflow. It runs tests and lint, builds the macOS DMGs and the Windows installer and portable exe, and publishes them with checksums as a GitHub release.

Architecture

Electron with a local Express server on 127.0.0.1:3457 and a plain JavaScript (ES modules) frontend, with no framework.

electron-main.js            Electron main process: starts the server, opens a sandboxed window
server.js                   Express entry point (browser mode)
src/backend/
  config/                   Server host/port and AWS clients per connection
  middleware/               Local-only API (Host/Origin), security headers, errors, validation
  controllers/, services/   DynamoDB, STS, SSO and Streams
  routes/api.js             /api routes
public/
  index.html, styles.css    The single-page app and its themes
  js/components/            UI components (DataViewer, QueryPanel, SqlEditor, TabManager, …)
  js/codegen/               Code generators, one module per language
  js/utils/, js/state/      Helpers and app state
scripts/build-prod.js       Production build (esbuild + electron-builder)
tests/                      Jest test suites

Security

• The local API acts with your AWS credentials, so it listens only on 127.0.0.1 and rejects requests whose Host or Origin is not the app. This protects against DNS rebinding and against websites in your browser calling it.
• Data read from DynamoDB is treated as untrusted. Everything rendered as HTML is escaped, and a strict Content Security Policy blocks inline scripts.
• The Electron window is sandboxed, has no Node.js access, cannot navigate away from the app and only opens https: links in your browser.
