At a glance

Where Crisp is better, and who should pick it

Crisp is a shared inbox first and a chat widget second. If any of these describe you, it's probably the better buy:

• Your customers write from many places. Crisp puts website chat, email, WhatsApp, Instagram, Messenger, SMS, Telegram and phone in one inbox, which comes with Essentials ($95). Hailbell is built around chat inside your app and on your website, with email only as a follow-up for replies the customer missed. If half your support arrives by email, Crisp handles it and Hailbell doesn't.
• You want a real knowledge base or tickets. Essentials ($95) adds a knowledge base with categories and languages, and Plus ($295) adds a ticketing system with a portal where customers follow their requests. Hailbell's help center is a plain list of articles with search, the AI answers from it, and only the web chat suggests articles so far, not the iOS and Android chat. There's no ticketing.
• You want to pay nothing. Crisp Free gives 2 seats and 100 customer profiles at $0, with the chat SDKs included. Hailbell has a 14-day trial and no free plan.
• Your team lives in Slack, or answers from a phone app. Crisp sends each conversation to a Slack thread you can reply in, and has its own operator apps for iPhone, Android, Mac and Windows. Hailbell has no Slack integration, and its iPhone app for answering on the go is coming soon.
• You support old phones. Crisp's iOS SDK goes back to iOS 13. Hailbell's native chat needs iOS 16 or Android 8.
• You sell on the web. Crisp syncs revenue from Stripe and orders from Shopify, WooCommerce and others into the inbox, which is exactly the context a web store needs.

Where Hailbell fits mobile apps better

• Push campaigns in the same SDK. Both send a push when you reply to someone who left the app. Only Hailbell sends campaigns: through APNs, FCM and Web Push from the dashboard, the REST API or MCP, with segments, each person's local time or usual hour, weather and occasion variables, quiet hours and daily caps. One campaign can cover an app's iOS, Android and web platforms. With Crisp you'd add a second tool for this.
• AI replies without credits. Hailbell's AI replies are unlimited on every plan. Crisp's Hugo is paid with AI credits: none on Free, $5 of credit on Mini, which Crisp says covers about 90 automated conversations, and $25 on Essentials, about 450. Hugo learns from more sources, including your website, past conversations and uploaded files, so it may answer more on day one.
• Official Flutter support. Hailbell's Flutter plugin and React Native package, Expo included, wrap the native Swift and Kotlin SDKs, so a cross-platform app gets the same native chat screen. Crisp's developer docs list iOS, Android and React Native. Its Flutter page points to community packages on pub.dev.
• Bug reports in the chat. If you turn it on, customers can shake the phone or tap your own "Report a problem" button to send a screenshot they can mark up, with their app version, device and last screens, into the same chat.
• Seats and apps don't count. Hailbell has unlimited seats and apps on every plan. Crisp includes 4 seats on Mini and 10 on Essentials, then $10 per extra agent a month, and each workspace is billed on its own.

Knowing who is writing: plan, purchases and paywall events

Most messages to a subscription app are about money: "I paid and it's still locked", "is there a yearly price", "I was charged twice". The right answer depends on what the person bought, and where they are in your funnel.

Crisp shows what you send it. Its SDKs take session data, events and segments from your app, and its Stripe integration shows revenue for web businesses. We found no RevenueCat or Superwall integration on its integrations page, so for App Store and Play purchases you'd send that data yourself.

Hailbell reads it from the subscription tools many apps already use. Each conversation shows the customer's plan, purchases and paywall events from Superwall and RevenueCat, next to their device and country. When someone writes "the trial didn't start", you can see they closed the paywall two minutes ago without buying and answer that. Then two cards finish the job:

• Offer cards. A button that opens one of your paywalls (a Superwall placement, or your RevenueCat paywall through a callback). The tap, "Not now" or purchase shows up in the chat, so you know if the offer worked.
• Review requests. Once you've solved the problem, a card opens the App Store review sheet, or your Play Store listing on Android. Ask happy customers only and never trade anything for a review; Apple and Google both forbid that.

Where you answer: Discord, Telegram, Slack or an AI agent

Both let you answer away from the dashboard, in different places. Crisp has Slack and Discord integrations that send conversations to your team and let you reply from there, plus its own apps on every platform. In Crisp, Telegram is a customer channel: your customers message you on Telegram and you answer in the Crisp inbox.

Hailbell gives each customer a Discord forum thread, or sends chats to your own Telegram bot, and you reply right there. The reply lands in the app, or as a push if the app is closed. For a solo developer, support then lives in an app that's already on the phone.

Both have official MCP servers that let an AI agent such as Claude Code or Codex work the inbox. Crisp's reads and searches conversations, sends messages and private notes, manages contacts and edits the knowledge base. Hailbell's reads and answers chats too, and each conversation comes with the customer's plan and Superwall or RevenueCat purchases, so an agent asked to "sort out today's billing questions" knows who paid what. Its replies wait as drafts a teammate sends unless an admin lets agents send in that app. Hailbell's MCP also sets up apps, writes the AI's notes and plans, previews and sends push campaigns.

Pricing for a solo app, a small team and an agency

Prices checked on November 11, 2026, on crisp.chat/en/pricing and hailbell.com.

Crisp prices per workspace and shows monthly prices only; its FAQ says you can switch to yearly billing in the app after you subscribe. Extra Crisp agents are $10 a month each.

The two count different things, so check yours before comparing. Crisp counts customer profiles, the people saved in your Crisp contacts. Hailbell counts monthly active users, the devices that opened your app with the SDK in a month. If only a small share of your users ever write in, Crisp's number can be the smaller one. Three examples:

• A solo developer with one app and 8,000 users a month. Hailbell Pro: $29, with AI replies and push campaigns. Crisp Free works while you stay under 100 profiles, with no AI. Past that, Mini is $45 with about 90 AI conversations, and push campaigns need another tool.
• A three-person team with 40,000 users that wants AI replies and push. Hailbell Scale: $79. Crisp Mini at $45 covers 4 seats if fewer than 5,000 people end up as profiles; otherwise Essentials at $95. Mini's AI credits cover about 90 AI conversations and Essentials' about 450. Add a push tool to either Crisp plan.
• An agency answering for eight client apps with 60,000 users between them. Hailbell Scale covers all eight apps and every teammate: $79. With Crisp, each client usually gets its own workspace and plan. Crisp takes 20% off 3 additional Essentials or Plus workspaces.

How to choose

• Customers reach you by email, WhatsApp, Instagram and your website: Crisp Essentials.
• You need a knowledge base with categories and languages, or ticketing: Crisp Essentials or Plus.
• You want chat for $0 and stay under 100 customer profiles: Crisp Free.
• Most support happens inside your iOS, Android or Flutter app: Hailbell.
• You sell subscriptions through Superwall or RevenueCat and want purchases and offers in the chat: Hailbell.
• You want push campaigns without a second tool: Hailbell.
• You're an agency answering for many client apps: Hailbell, since apps and seats are unlimited on one plan.

Both have a 14-day trial with no card, so the fastest test is to add each SDK to a debug build and send yourself a message. Try Hailbell or read the docs. If you're weighing other tools too, see Crisp alternatives for mobile apps.

Is Crisp or Hailbell cheaper for a mobile app?

It depends on what each one counts. Crisp is priced per workspace and caps customer profiles: Free covers 100, Mini ($45 a month) 5,000 and Essentials ($95) 50,000. Hailbell counts monthly active users of the app: Pro is $29 a month for 10,000 and Scale $79 for 100,000, with unlimited seats and apps, AI replies and push campaigns included. If only a small share of your users ever write, Crisp's count can be the smaller one. Prices checked November 11, 2026.

Does Crisp have a Flutter SDK?

Not an official one. Crisp's developer docs cover iOS, Android and React Native, and its Flutter page points to community packages on pub.dev. Hailbell's Flutter plugin is official and wraps its native Swift and Kotlin SDKs.

Can Crisp send push notification campaigns to app users?

Crisp's mobile SDKs send a push when a customer gets a new chat message. Crisp Campaigns covers email, chat, SMS and WhatsApp, and its campaigns page lists no mobile push campaigns. Hailbell includes push campaigns through APNs, FCM and Web Push on every plan.

Can I reply to customers from Discord with Crisp or Hailbell?

Both. Crisp has a Discord integration and a Slack integration for replying to customers. Hailbell gives each customer a Discord forum thread, or sends chats to your own Telegram bot, and you reply there. Hailbell has no Slack integration.

Can an AI agent answer chats in Crisp or Hailbell over MCP?

Hailbell's reads and answers chats with each customer's plan and purchases from Superwall or RevenueCat, and also runs push campaigns. Hailbell's agent replies wait as drafts for a teammate unless an admin lets agents send.
