Postiz and Publer alternatives: what AI replies cost (2026)

What a scheduler with AI replies costs depends on how it bills: flat, per user or per contact. BetterSocials is our pick for creators, local businesses and small agencies who answer their own messages: it posts like Postiz and Publer, then drafts or sends replies in your voice, for $29 a month for four accounts. Agorapulse fits a team that assigns messages, and Metricool fits a buyer who wants keyword flows on a plan they already pay for.

The cost question: a scheduler plus an AI inbox

Postiz and Publer get your posts out on time. The second bill is what you pay so the comments and DMs those posts bring in get answered.

You can pay it four ways. In hours, by hand. In a per-seat inbox. In a per-contact DM tool. Or in one flat plan that does both jobs.

Every price below carries the month it was read: Agorapulse in July 2026, Postiz and Vista Social in September, Hootsuite, Sprout Social and Manychat in October, and Metricool in November. Our assumption is one person, or a team of two, answering the account's own comments and DMs.

Metricool's $12 buys the Flows add-on, which sits on top of a Metricool plan. Hootsuite and Sprout Social charge per seat, so a second person doubles the bill: $99 per user on Hootsuite and $199 per seat on Sprout Social, each paid twice, both billed annually.

That gap is the whole argument for a flat plan when one or two people do the answering.

BetterSocials: posting plus AI replies at one price

BetterSocials is best for creators, local businesses and small agencies whose comments and DMs turn into customers. It is an AI social media manager: it posts to Instagram, Facebook, YouTube, Threads, TikTok and LinkedIn, then collects every comment and DM in one Inbox.

AI replies has two sections, Comments and DMs, and each has three settings. Off means you write every reply yourself. Draft for me writes a draft in your voice the moment a comment or DM arrives, and nothing posts until you approve it. Reply in my voice answers everyday comments 1 to 5 minutes after they land, and a DM gets an answer in about a minute.

Questions get more care. They wait in Needs reply unless you turn on Answer questions too, and that switch only works once you have written at least one AI rule, such as your prices, hours or booking link. When your rules don't cover what someone asked, the AI doesn't guess.

Keyword DMs are a separate tool. A word in an Instagram or Facebook comment sends that person a DM with your link, with no flow builder and no per-contact bill.

BetterSocials plans run Creator at $29 a month for four accounts and 1,000 AI credits, Pro at $49 a month for six accounts and 2,000 credits, and Team at $99 a month for 12 accounts, unlimited teammates and 4,000 shared credits. Each AI reply or draft uses 1 credit. When credits run out the AI pauses; it never charges more on its own. Every plan has a 7-day free trial (card required) and unlimited contacts.

Leaving Postiz: what an answering tool adds to the bill

Yes, Postiz users can move to a tool that also replies to comments and DMs with AI. Postiz itself is a publisher: open source, self-hostable, 5 to 100 channels, with Standard at $29 a month on monthly billing, Team at $39, Pro at $49 and Ultimate at $99. Postiz has no inbox. Its post comments feature schedules your own first comment under your own post.

So a Postiz user who wants answers has two routes.

The first keeps Postiz and adds a DM tool. That means Postiz Standard at $29 a month plus Manychat Pro at $39 a month, two bills that buy keyword flows for up to 2,500 active contacts. The second moves posting and answering into one tool.

Which one fits depends on who answers:

• You answer alone. BetterSocials Creator covers posting and AI replies to comments and DMs across four accounts, for less than the Postiz plus Manychat pair.
• Two or more people share the inbox. Agorapulse assigns comments and messages and offers AI reply suggestions, at $79 per user a month on annual billing.
• You want DM automations with room to test. Vista Social Professional includes a social inbox and DM automations, with a 14-day trial and no card.

Leaving Publer: inbox alternatives by job

Yes, Publer users have several alternatives with an inbox that answers comments and DMs. The right one depends on the job the inbox does, not on how many networks it posts to.

BetterSocials suits the person who answers in their own voice across six platforms and wants comments and DMs drafted or sent by AI. Agorapulse suits a team: assignment, reply collision detection, saved replies and AI reply suggestions all sit in its inbox.

Vista Social Professional costs $79 a month on monthly billing, or $758 a year, and pairs its inbox with DM automations. Metricool reads YouTube comments, including on its free tier, and its Flows add-on handles keyword replies.

If you are already paying for Hootsuite or Sprout Social, both include an inbox from their Standard plans. Hootsuite's inbox does not include YouTube comments.

Buffer is the lighter option. Its Community inbox covers comments on every plan but not DMs, so Instagram and Facebook messages stay in the phone apps.

Where an AI inbox can reply, platform by platform

Instagram, Facebook and TikTok DMs can all get AI answers in BetterSocials, and every tool here works inside the same platform APIs. Those APIs set the limits, not the vendors.

• Instagram: a business can reply to a DM only within 24 hours of the person's last message. Past that window, most tools can't send a DM, though you can still answer in the Instagram app.
• Facebook: Page comments and Messenger DMs both reach the inbox.
• TikTok: DMs are reply-only, with at most 10 replies within 48 hours of the person's last message, and the account must be a Business account. TikTok only lets apps answer DMs for accounts outside the UK and Europe.
• YouTube: public replies only, because YouTube has no DM API for any tool.
• Threads and LinkedIn Company Pages: comments and public replies. A LinkedIn personal profile is posting and analytics only.

A TikTok comment cannot trigger a private DM on any tool outside TikTok's limited rollout in Vietnam, Thailand and Indonesia. We cover the TikTok side in more depth in TikTok comment replies with AI: 2026 rules for businesses.

Keyword DMs or AI replies: what each one bills by

Manychat bills by the contact. Pro is $39 a month for 2,500 active contacts, and each extra contact costs $0.05, billed monthly. A post that brings in a crowd of new contacts raises the bill.

Metricool bills by the run. Each Flows add-on is $12 for 2,500 monthly executions, and each execution past that costs $0.01, on top of the Metricool plan.

BetterSocials bills neither way for keywords. Keyword automations and contacts are unlimited on every plan, and only the AI writing is metered, at 1 credit a reply.

The choice follows your posts. If your captions say "comment GUIDE for the link", a keyword tool does the job. If the comments are questions about price, timing and fit, each one needs its own answer, and that is what AI replies cover.
