Two-way messaging — inbox & auto-reply
† Telegram is an early, proof-of-concept integration: it connects as a bot and handles private 1:1 DMs (text) only — a bot can't message someone until they start the chat. Groups, channels and Telegram Business account inboxes aren't supported yet; deeper Telegram integration is on the roadmap.
Publishing — schedule & post
Messaging channels get the full inbox + auto-reply; publishing channels schedule and post. Each is one TypeScript provider class — and you can add your own.

PostStack
when you need scheduling, auto-reply, AI-drafted replies, comment-to-DM funnels, drip sequences, CRM, and a REST API across Facebook, Instagram, YouTube, Telegram & Gmail — on your own server, with no per-contact fees.
01 · Capture
A follower drops “PRICE” under your Instagram post. PostStack matches it against your rules in real time.
02 · Convert
PostStack replies publicly and slides the conversation into the DMs — comment-to-DM, automatically, within Meta's window.
03 · Nurture
The contact is tagged, saved, and enrolled into a timed follow-up sequence. No lead slips through.

Everything you'd otherwise stitch together from a scheduler, a chatbot, and a CRM — built into a single self-hosted platform.
Unified inbox
Handle DMs, comments, messages and emails across Facebook, Instagram, YouTube, Telegram and Gmail — manual replies, tags, subscriptions, and contact history without jumping between tools.
Auto-reply rules
Build rules for comments, keywords, postbacks, welcome events, stories, and reactions. Reply publicly, privately, or both — with AI rephrase and interactive buttons.
AI-drafted replies
Off-script comments and DMs get an AI-drafted answer waiting in your inbox to accept, edit, or reject — plus an on-demand “Generate reply” button. Never auto-sent by default, and you bring your own model.
Drip sequences
Create multi-step sequences with delays, manual enrollment, and automatic enrollment from the exact rule that captured intent.
Publishing
Plan multi-platform posts, schedule delivery, attach media, publish first comments, and trigger Auto-Story workflows from one screen.
CRM
Tags, subscriptions, contact profiles, and thread history stay connected to the person who just commented or messaged you.
API-first
Every serious capability is designed around /api/v1 and documented with Scalar for builders who want to connect PostStack to their stack.
This is exactly how PostStack answers comments and DMs: match the intent, reply in public or private, then hand off to a sequence — automatically.
Tap a keyword a follower might send
@follower
Instagram · DM
Gate a lead magnet behind a real follow. When someone taps to claim, PostStack live-checks whether they actually follow your Instagram — delivers the magnet if they do, or loops them back with a “follow first” prompt until they do. No honour system: it verifies with Instagram.
Try it — is this person following you?
Instagram only — verified live via the messaging API (is_user_follow_business). Facebook has no public follow graph, so the gate stays open there.

Run automation for multiple brands without pricing that grows every time a client's audience grows.
Answer product questions, recover comment intent, and move shoppers from public comments to private follow-up.
Send lead magnets when someone comments a keyword and keep every subscriber in a lightweight CRM.
Self-host the stack, inspect the code, and connect your own tools through a predictable API surface.
Ask for an email or phone number with a single tap — Facebook and Instagram pre-fill it from the user's profile, so they confirm instead of typing. It lands on the contact in your CRM and fires a webhook the moment it's captured.
01 · Ask with one tap
A rule sends an "email" or "phone" quick reply. Meta pre-fills it from the user's profile — one tap, no typing, no typos.
02 · Stored in your CRM
The captured email/phone is written straight onto the contact, alongside tags, subscription state and conversation history — yours, on your server.
03 · Webhook to anywhere
Capturing a contact fires a signed outbound webhook, so you can push it to Listmonk, n8n, a mailing list or any tool — no lock-in, no built-in email vendor to rent.
Outbound webhooks are a PRO feature; the captured contact carries its id so the receiver can pull email, phone and tags.
A comment, DM, message or email arrives, PostStack processes it, and writes it straight into your Postgres and your REST API — not into someone else's SaaS where your audience sits behind a per-contact paywall.
SaaS lock-in: your audience lives on their servers.
PostStack: it lives on yours.
PostStack wasn't supposed to be a product. We were running automation for our own brands and got tired of watching the bill climb every time an audience grew. So we built a self-hosted layer on top of the social platforms' APIs — for ourselves.
Then people asked for access. Then their friends did. Today it's a source-available platform for anyone who believes their data and their automation should belong to them.
We're just getting started. Come build with us.

We ship in public — follow along or request a channel on GitHub. Open GitHub →
A common myth: that Meta has to approve your app before you can automate Instagram & Facebook. You don't — not for your own accounts. Connect Instagram directly (no Facebook Page required) and go.
Your own accounts
No reviewInbox, auto-reply, comment→DM and drip sequences all work under Meta's default Standard Access. No App Review, no Business Verification. Connect an Instagram account directly with Instagram Business Login — no Facebook Page needed — and still get DMs and the follow-gate.
Clients' accounts
Needs reviewOnly if you operate other people's accounts (an agency / reseller setup) does Meta need Advanced Access — App Review + Business Verification. That's the line, and it's optional.
Same story across the board: every channel PostStack supports today — Facebook, Instagram, YouTube, Telegram and Gmail — runs on a standard developer app you create yourself. No weeks-long app review and no identity or business verification to use your own accounts — just normal app configuration (Telegram is literally one bot token).
One-time setup: switch the Meta app to Live mode (a toggle, not a review) so production webhooks flow.
See exactly what needs reviewSelf-host the core at no cost. Pick a license when you want the full feature set and support — yearly or one-time.
For builders who want to run the core system themselves.
Launch price. Commercial license, priority support, and a year of updates.
Launch price. One-time license for teams who keep running their own stack.
🚀 Launch pricing — lock in the founding rate while it lasts. Paid licenses are issued through Sellf; choose yearly or lifetime at checkout.
Yes for self-hosting. The target setup is Docker Compose on a VPS — a single deployment that serves both the dashboard and its marketing page from the same domain.
Both are available: PRO is a yearly license, and Lifetime is a single one-time license with no recurring fee.
For two-way messaging (inbox, auto-reply, comment-to-DM): Facebook, Instagram, YouTube, Telegram and Gmail are live today — connect multiple accounts of each. Instagram can be connected directly via Instagram Business Login (no Facebook Page required, DMs at Standard Access) or through a linked Facebook Page. Gmail is a two-way reply/inbox channel (filter by label or query, read-only on your mailbox). Telegram is an early, proof-of-concept integration — it connects as a bot for private 1:1 DMs only (no groups, channels or Telegram Business inboxes yet, and no publishing); deeper Telegram support is on the roadmap. For publishing & scheduling you can also post to TikTok, X, LinkedIn and Threads. Coming next on the messaging side: WhatsApp, SMS (Twilio/SMSAPI), generic email (IMAP/SMTP) and Discord — each ships as one provider class. (TikTok, X, LinkedIn and Threads stay publish-only — those platforms don't expose an inbound-messaging API.)
Only if you turn it on, and only to the model endpoint you configure. AI-drafted replies are bring-your-own-key: point them at OpenAI, a self-hosted model, or any OpenAI-compatible endpoint via AI_BASE_URL. Drafts are never sent to the contact automatically — they wait in your inbox for you to accept, edit, or reject (optional per-channel auto-send is off by default). It's a PRO feature.
Your database and media storage stay under your control. No per-contact lock-in — operational data lives on infrastructure you manage.
For production usage with Meta permissions, expect the normal Meta app setup and review. PostStack gives you the operating layer, not a way around Meta policy.
Yes. The app is API-first and TypeScript-based, so you can drive it through /api/v1 or extend the provider pattern in the codebase.
The free self-host runs the core system. A PRO or Lifetime license unlocks the full feature set, commercial use, and priority support.
Reach out and we'll make it right. The whole point of PostStack is removing lock-in — that includes how you feel about the license.
Get PostStack and run it on your own server today — no per-contact fees, no lock-in.
