Comment a keyword, get a public reply and a DM. Automatically.
Oh Daddy is a minimal, self-hosted, ManyChat-style tool for Instagram and Facebook comment automations. Someone comments a keyword on your post, they get a public reply right away plus a DM straight to their inbox. No human involved.
No AI, no chatbot builder, no 40 platforms you'll never touch. Just keyword in, reply + DM out.
Someone comments a keyword under your post, they get a public reply (rotated so it's not the same line every time) and a private DM via Meta's Private Replies API.
Same person comments the same keyword twice in 24 hours? They only get replied to once. No spam, no annoyed followers.
Scope an automation to one specific post, or leave it open to every post on the account.
Dashboard (stats), Automations (keyword rules), Accounts (connect Meta via OAuth), Settings (credentials + webhook config).
Every send claims its row in Postgres before it touches the Meta API. Webhook retries and Inngest retries can't send the same reply twice.
All sends across every connected account share one hard cap of 195 comments/hour, just under Meta's Graph API ceiling. Doesn't matter if you've got 1 account or 5, the whole deploy can never trip Meta's rate limit. Overflow gets queued and delayed, never dropped.
Access tokens and DB-stored settings are AES-256-GCM encrypted. A leaked backup or a raw SQL dump never hands over a live Meta token.
| Oh Daddy | ManyChat | |
|---|---|---|
| Cost | ~$5/month total, your own hosting | Starts at $29/month, per account |
| Accounts | Add as many as you want (recommend keeping it to 4-5) | Pay-per-account, adds up fast |
| Hosting | Self-hosted, you own the server and the data | Their cloud, your data lives on their servers |
| Source | Open source (AGPL-3.0), read every line | Closed source |
| Scope | Instagram + Facebook comments, on purpose | Instagram, Facebook, WhatsApp, Telegram, SMS, AI chatbots, and more |
| Vendor lock-in | None, it's just Postgres + Next.js | Yes |
If you need the full chatbot suite, ManyChat is a solid product. If all you need is "keyword comment → reply + DM" for a handful of accounts, this is a lot cheaper and it's yours.
- Fork this repo.
- Open it in Claude Code / GG Coder.
- Run
/setup-railway.
That's it. It provisions Postgres, secrets, a self-hosted Inngest server, and deploys the app for you. It prints your dashboard login password (ADMIN_PASSWORD) once at the end, save it. Meta/Instagram credentials get entered afterward in the deployed app's /setup wizard.
You need: a Railway account (create one here), and the Railway CLI installed and logged in (railway login).
