NullCast
A native Windows studio for Discord webhook messages.
Build rich embeds, attach files, add link buttons, and watch a live preview update as you type. When it looks right, send it to any webhook, edit your posts in place, or save the whole thing as a reusable template.
If you've ever put together announcements in a browser webhook builder, NullCast is that workflow as a real desktop app: faster, snappier to compose, and with saved profiles, templates, and history so you're not rebuilding the same message every time.
- Message content plus up to 10 full embeds, with live preview.
- Link buttons (components) and file attachments.
- Edit already-posted messages in place, no re-pinging.
- Import and export Discord webhook JSON.
- Saved webhook profiles, saved message templates, and a full send history.
One-time purchase, yours forever.
