favgif: search, favorite, and post GIFs in Slack

favgif is a Slack app that lets teams search, favorite, and post GIFs to channels right inside Slack — without ever leaving the chat.

favgif slash command Getting started with the /favgif slash command right from the message box

My Role

Solo project — product, Slack integration, and the entire backend.

Search via slash command or global shortcut — trending GIFs (Klipy) or targeted search (Klipy, Tenor)
Post the chosen GIF to the channel the selection was opened from
Favorites saved per user and workspace, ready to recall
Insert a link — direct GIF URLs or Giphy pages are automatically normalized into a GIF file
Pagination of results (Next/Previous)

GIF selection in the modal — post straight to the channel with "Post"

favgif favorites Quickly pick a favorite or insert one via link

Backend as a single Edge Function — the entire Slack interaction logic (slash commands, shortcuts, modals, block actions) runs in one Supabase Edge Function (Deno), with Postgres for per-user favorites.
Multiple GIF providers — Klipy, Tenor, and Giphy behind a unified interface, including normalizing Giphy page URLs into direct GIF files.
Slack interaction model — cleanly mapping modals, pagination, and posting with the right channel context through Slack's interaction payloads.

Every workspace runs its own Supabase instance, Slack app, and GIF provider API keys — nothing is shared between workspaces.
