NotiFixed vs Knock

A Knock alternative that puts 19 languages and per-customer push on every plan

NotiFixed is a notification API for B2B SaaS: one call sends to an in-app feed, mobile push and web push, in 19 languages.

Knock is a broad messaging platform: a free plan, then Starter at $250 a month, with translations and per-tenant branding on Enterprise. NotiFixed is smaller on purpose and puts those on the free plan.

The cheapest plan that includes each feature
Cheapest plan with	Knock	NotiFixed
Translations	Enterprise	Free
Per-customer branding	Enterprise	Free

Languages and your customers' own push, without an Enterprise contract

On Knock, translations and per-tenant branding are Enterprise features, and the first plan after Free is $250 a month. On NotiFixed, all 19 languages and push under each customer's own name and icon come with the free plan, and the first paid plan is $50 a month. Knock's per-tenant branding is a logo and colours for email. NotiFixed's is push: each customer's notifications go through their own Apple and Google accounts.

If each of your customers has their own app, NotiFixed for multi-tenant SaaS shows how their push ends up under their own name.

That is the whole difference. The rest of this page is detail.

Who should pick which

Pick NotiFixed if

Your users read the product in more than one language, and you are not on an Enterprise contract.
You have outgrown 10,000 a month, and $250 is too big a step.
Your privacy review would rather you sent no names or emails.

Stay with Knock if

Teams that want email, SMS, chat and push from one workflow builder, with UI ready to drop in.

You need email, SMS or Slack alongside push and the in-app feed.
You want ready-made React components for the feed instead of building your own.
You design flows on a canvas, with batching, branches and throttles.
Your whole team needs seats on the free plan.

Switching: the words map

In its December 2025 letter, Knock set out to serve engineering, growth and marketing teams, and on 14 October 2026 it launched Goals. On 31 August 2026 its status page reported a partial outage of notification delivery, for under two hours. If the notifications are the part you use, moving is mostly renaming.

Knock	NotiFixed
workflow	type. One type per kind of notification. Its key is what you send.
delay step	workflow. Order and timing per type, set in the console rather than on a canvas.
template	template. One row per language, instead of one template per channel step.
channel	channel. in_app for the feed, push for every device somebody is signed in on.
in-app feed	feed. An inbox. Most teams keep the one you start with.
tenant	customer. Their own Apple and Google credentials, set up with you.
user	user id. Just the id you already use. No name, email or phone number.
Not in NotiFixed	Batch, branch and throttle steps, per-user preferences, email, SMS and chat channels, and in-app guides. Left out on purpose.

The order to move things in is in the switching guide.

One call

The same request as the quickstart. Your user ids, the type and its data; we write the words.

POST https://app.notifixed.com/v1/notifications

curl https://app.notifixed.com/v1/notifications \
  -H "Authorization: Bearer $NOTIFIXED_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "invoice.paid",
    "recipients": ["user_8812"],
    "payload": {
      "invoice_number": "INV-2026-0041",
      "amount": "€2,400",
      "customer_name": "Globex"
    }
  }'

In the feed: the finished sentence in each person's language, plus the raw data.
On phones: a push through your customer's own Apple or Google account, under their icon.
In browsers: a web push on every browser they have allowed.

Read the quickstart, about ten minutes from sign-up to the first notification.

Questions about
NotiFixed and Knock

Does NotiFixed store my users' emails?+

No. NotiFixed holds an id you already use, a language, and the labels you choose. No names, no email addresses, no phone numbers.

Does NotiFixed send email or SMS?+

No. Push and in-app only. If you need email, forward a NotiFixed event to Resend or Postmark.

Is NotiFixed a good Knock alternative?+

If you need push and an in-app feed in several languages, with each customer's push under their own name and icon, yes, and those come on the free plan. If you need email, SMS or chat in the same workflow, or ready-made React components, Knock fits better.

How do I move from Knock to NotiFixed?+

Each Knock workflow becomes a NotiFixed type, its templates become one row per language, and your trigger becomes one POST to /v1/notifications with the same user ids. We can move the feed and push with you in a 45-minute pairing session. Switching guide →

Can each of my customers send push under their own app icon?+

Yes, on every plan, Free included. Each customer's push goes out through their own Apple and Google credentials, so it arrives with their name and icon. We set that up with you.

What does NotiFixed cost after the free plan?+

Free covers 10,000 notifications a month. Pro is $50 a month for 250,000, or $25 a month kept forever if you join by the end of November 2026. See pricing →
