Show HN: FYI - Product Events Tracking and Notifications for Elixir Phoenix Apps (opens in new tab)

I'm an indie hacker who builds a lot of small Phoenix apps, and I got tired of setting up LogSnag/Mixpanel/whatever for every project just to get pinged when someone signs up or makes a purchase.

My favorite thing about Elixir is not needing third parties -Phoenix.PubSub instead of Redis, Oban instead of Sidekiq, LiveView instead of React. So I built FYI to bring that same philosophy to product event tracking and notifications.

What it does: - Track events with one line: `FYI.emit("purchase.created", %{amount: 4900})` - Get Slack/Telegram notifications when things happen - Route specific events to specific channels (e.g., waitlist.* → Slack, errors.* → Telegram) - Beautiful admin UI at /fyi with live updates, search, and filtering - Drop-in feedback widget (installs into your codebase, not an iframe)

Key features: - Zero external dependencies - just BEAM, Ecto, and Phoenix - One command setup: mix fyi.install - Integrates with Ecto.Multi so events only emit after transactions commit - Fire-and-forget - failures never block your app - Feedback component lives in YOUR repo so you can customize it

Philosophy: No Oban queues, no retries, no backoff. Just simple HTTP notifications and Postgres persistence. Think "LogSnag but self-hosted and Elixir-native." The installer even copies a feedback component into your codebase instead of making you use an external widget, so you can style it however you want.
