Pusher Channels Free tier4.3· Free · paid from $49/mo Pusher Channels is the long-standing default for 'make this screen update without a refresh'. You publish to a channel, connected clients receive it, and Pusher operates the socket infrastructure. It is realtime transport rather than notification orchestration: no templates, no per-user preferences, no email fallback — but for live dashboards, collaborative cursors and in-app toasts it is a few lines of code. * ✓Working realtime in minutes * ✓Predictable flat tiers * ✓Mature SDKs for every platform [Pusher Channels pricing & review ](https://appstackbuilder.com/tools/pusher)[Ably vs Pusher Channels ](https://appstackbuilder.com/compare/ably-vs-pusher) K ### 2. Knock Free tier4.6· Free · paid from $250/mo Knock is the polished commercial take on the same problem Novu solves in the open. Its strengths are the workflow editor non-engineers can actually use, genuinely good batching and digest logic, and a preference centre that handles the per-user, per-channel matrix properly. The jump from a free developer tier to $250 is steep and is the main reason teams weigh it against self-hosting. * ✓Best-in-class batching and digests * ✓Preference centre handles the hard cases * ✓Workflow editor non-engineers can use [Knock pricing & review ](https://appstackbuilder.com/tools/knock)[Ably vs Knock ](https://appstackbuilder.com/compare/ably-vs-knock) N ### 3. Novu Free tier4.6· Free · paid from $30/mo Novu is the open-source answer to writing notification plumbing yourself. You define a workflow once — with steps, digests, delays and per-user preferences — and it fans out to whichever providers you have configured, including a React inbox component you can drop into your product. The whole thing can be self-hosted, which makes it the rare row in this category where building and buying are genuinely close. * ✓Fully open source and self-hostable * ✓Drop-in React inbox component * ✓Bring your own delivery providers [Novu pricing & review ](https://appstackbuilder.com/tools/novu)[Ably vs Novu ](https://appstackbuilder.com/compare/ably-vs-novu) C ### 4. Courier Free tier4.4· Free Courier's distinguishing idea is the template studio: designers edit notification content visually, across every channel, without a deploy. Routing rules decide which channel a given user gets and in what order, with automatic fallback. Pricing is the simplest in the category and also the least bounded — $0.005 per send with no flat tier above the free 10,000, so cost tracks volume exactly. * ✓Visual template studio across all channels * ✓Automatic channel fallback routing * ✓Pay exactly for what you send [Courier pricing & review ](https://appstackbuilder.com/tools/courier)[Ably vs Courier ](https://appstackbuilder.com/compare/ably-vs-courier) O ### 5. OneSignal Free tier4.4· Free · paid from $19/mo OneSignal is the mass-market end of this category: it is a messaging and engagement platform first, with push notifications as the wedge, and it serves marketers as much as engineers. Free covers a real amount of web push, and the Growth tier starts at $19 plus usage priced by channel — monthly active mobile users for push, subscribers for web. Where Novu and Knock orchestrate your product's notifications, OneSignal is where campaigns get sent. * ✓Free tier covers real production web push * ✓Strong mobile push SDKs * ✓Campaign and journey tooling included [OneSignal pricing & review ](https://appstackbuilder.com/tools/onesignal)[Ably vs OneSignal ](https://appstackbuilder.com/compare/ably-vs-onesignal) M ### 6. MagicBell Free tier4.3· Free · paid from $249/mo MagicBell leads with the component rather than the pipeline: a bell icon and notification centre you drop into an app and have working the same afternoon, with read state, preferences and real-time updates handled. The API behind it fans out to email, push and Slack when a user does not see the in-app message. Pricing jumps hard from free to $249, which positions it at funded teams rather than side projects. * ✓Prebuilt inbox UI for four platforms * ✓Fastest path to a working notification centre * ✓Real-time read state out of the box [MagicBell pricing & review ](https://appstackbuilder.com/tools/magicbell)[Ably vs MagicBell ](https://appstackbuilder.com/compare/ably-vs-magicbell) ## Frequently Asked Questions What are the best alternatives to Ably in 2026?⌄ The best Ably alternatives in 2026 are Pusher Channels, Knock, Novu, Courier, OneSignal.
