About this app

HookDeck: Webhook Sender is a clean, client-side workstation engineered for testing, managing, and dispatching Discord, Slack, and custom HTTP webhooks directly from your device.

Whether you are testing webhook integrations, broadcasting announcements, or debugging payloads, HookDeck gives you full control with an intuitive mobile workflow.

KEY FEATURES:

MULTI-PERSONA IDENTITY SYSTEM
• Create and manage multiple sender profiles with bespoke names and avatars.
• Set custom avatar image URLs or dynamic monogram badges.
• Organize profiles with tonal tags (Professional, Playful, Direct, Urgent).

MULTI-PLATFORM WEBHOOK MANAGER
• Automatic platform detection for Discord Webhooks and Slack Incoming Webhooks.
• Support for custom HTTP REST endpoints with arbitrary payloads.
• Secure local endpoint storage with masked URLs and 1-tap clipboard copying.

SECURE FILE & MEDIA ATTACHMENTS
• Attach photos, logs, and files via Android’s native Photo Picker / Storage Access Framework.
• High-performance multipart streaming (payload_json + files[0]) built for Discord.
• Resilient 90-second connection timeout prevents premature aborts on large uploads.

LIVE WYSIWYG PREVIEW
• Live message simulation cards reflect actual Discord and Slack message formatting.
• Verify markdown text and attachment presence before hitting dispatch.

TELEMETRY & AUDIT TRAIL
• Review round-trip latency measured to the millisecond (ms).
• Inspect delivery HTTP response codes (200 OK, 204 No Content, 400 Bad Request).
• High-contrast feedback toasts with instant status confirmation.

100% PRIVATE & ON-DEVICE
• Zero Middleman Servers: Requests travel directly from your phone to your designated webhook endpoint over secure TLS/HTTPS.
• Zero Trackers: No advertising, no analytics SDKs, and no tracking scripts.
• Local Storage: All profiles, endpoints, and history logs stay safely on your device.
Send and test Discord, Slack & custom webhooks with custom sender profiles.
