How Notifly compares.
Claims about the other vendor's limits link a primary source wherever one exists — their documentation, pricing page, or public issue tracker. No benchmarketing.
Notifly is hosted notification infrastructure for product teams: one API for email, SMS, push, in-app inbox and chat, a visual workflow editor, and the team features — roles, translations, audit logs — on an ordinary paid plan. The six pages below set that against the platforms people evaluate alongside it.
What stays true in every comparison
Flat plans, metered on events
Notifly bills a flat monthly price and meters the events you trigger — not monthly active users, and not individual sends. Subscribers are unlimited on every plan, including the free one, so growing an audience does not by itself move you up a tier. Volumes above a plan are sized on request rather than billed as automatic overage.
A free plan that is a real workspace
10,000 events a month, all five channels, all 70+ providers, up to 20 workflows and 3 team members — no credit card and no sales call. The free plan is the same product, not a demo: the API, the workflow editor and the in-app inbox are all there.
Team features on a $149 plan
Role-based access control, translations (i18n), audit logs, custom environments and webhooks, unlimited members and workflows, and 90-day retention are all on the $149 Team plan. Enterprise exists for SSO (SAML/OIDC), SCIM directory sync and custom retention — not as the gate for basic collaboration.
Built on the Novu engine, operated for you
Notifly runs on the Novu notification engine — a NestJS API and worker on MongoDB and Redis — operated as a hosted service by Devino Solutions Inc. The client SDKs are open source and published on npm under @notiflyio; the platform itself is a commercial product with nothing to install.
The comparisons
Novu alternative
The engine relationship, and where each product puts the team features: RBAC, translations, audit logs, org switching, unlimited members and environments.
OneSignal alternative
OneSignal's free plan caps mobile push and in-app at 1,000 MAU from Sept–Oct 2026. Notifly meters events, not people — subscribers are unlimited on every plan.
Knock alternative
Knock bills per message and reserves SAML SSO, SCIM, custom roles, and translations for its Enterprise plan. Notifly's flat plans start at $0 and put roles and translations on a $149 tier.
Courier alternative
Courier bills $0.005 per send once past a 10,000 free tier and lists RBAC and the audit trail under Enterprise. At 50,000 a month: $250 against a $19 flat plan.
SuprSend alternative
SuprSend counts every channel a notification reaches and keeps RBAC, audit trail and SAML SSO on Enterprise. Notifly meters the trigger event and puts roles on a $149 plan.
MagicBell alternative
MagicBell's free Builder plan includes 1,000 deliveries a month and its next plan is $249. Notifly's free plan includes 10,000 events, with a $19 plan in between.
Pricing breakdowns
When the question is what one vendor charges rather than which product to pick, these pages lay out its plans, its free tier and worked monthly bills, each figure sourced and dated.
OneSignal pricing
What OneSignal costs in 2026: the free plan and its 1,000 MAU cap, Growth at $19 plus $0.012 per mobile MAU, worked bills at 1,000 to 100,000 MAU, and Notifly's flat plans beside them.
Knock pricing
What Knock costs in 2026: the free Developer plan, Starter at $250 with 50K messages then $0.005 each, worked bills at 10,000 to 500,000 messages, and Notifly's flat plans beside them.
Courier pricing
What Courier costs in 2026: the free Developer plan with 10,000 sends, Business at $0.005 per send, worked bills at 10,000 to 1,000,000 sends, that email and SMS provider fees bill separately on top, and Notifly's flat plans beside them.
How to read these pages
Each comparison is a table of capabilities with three columns: the capability, what Notifly ships, and what the other platform ships. Every cell that makes a claim about the other platform carries a [source] link to that vendor's own documentation, pricing page or issue tracker — so you can check it, and so it is obvious when a claim has aged out.
The Notifly column is the shipped limit, read from the same plan constants the pricing page and the billing code use. Pricing changes therefore change the comparison tables in the same commit, not weeks later.
None of these pages claims a platform is bad. They exist because notification tools differ on three axes that are hard to see from a marketing page — how you are metered, which plan unlocks roles and translations, and whether you can run the engine yourself — and those are the axes the tables cover.
Evaluating Notifly itself
Pricing lists every plan limit and answers the questions that decide a migration: what counts as an event, what happens when you run out, and what the opt-in 14-day Pro trial includes.
Developers is the integration surface — the REST API, the generated reference, the OpenAPI document and the remote MCP server — and the documentation covers channels, workflows, the in-app inbox and security.
Integrations lists every email, SMS, push and chat provider you connect with your own keys, with setup guides that quote the exact fields each provider asks for.
