A Knock alternative for .NET and Blazor teams

Knock is a well-regarded notifications-infrastructure product. If you are a .NET, ASP.NET Core, or Blazor team evaluating it, the useful question is not "is Knock good" — it is — but "is it the right fit for a .NET stack." This post answers that from the Notavia side, including where Knock is the better choice.

A note on fairness first. This is written by the Notavia team, and notification products change their features and pricing often. So rather than publish a feature-by-feature comparison that would be out of date the week after we wrote it, everything below describes what Notavia does. For what Knock does, read Knock's own documentation — it is the only source that is current, and it is the one we would want you to check.

The .NET question

Most notifications-infrastructure products are Node/TypeScript-first: the SDK, the examples, and the docs assume a JavaScript backend, with .NET a secondary target or a community wrapper. For a team whose stack is C#, ASP.NET Core, and Blazor, that tends to show up as thinner SDKs, fewer .NET examples, and no first-class Blazor UI. Notavia is built .NET-first — that asymmetry is the entire reason it exists.

What Notavia brings to a .NET stack

| | Notavia | |---|---| | .NET / Blazor SDK | Native, including a drop-in Blazor inbox component | | In-app inbox | A framework-agnostic web component and a Blazor component | | Channels: email, in-app, SMS, chat | One API | | White-label / OEM (your brand) | Core offering | | EU data residency | Germany by default | | Self-host | Docker / Helm, offline licence | | Pricing model | Free to 1,000 sends/mo, predictable tiers | | AI / MCP server | Yes — drive it from Cursor or Claude |

Notavia's SDKs are published, but the service is not yet open for self-serve sign-up. A mature product you can buy today is a real advantage over a pre-launch one, and you should weigh it.

When Knock is the better choice

Be honest with yourself here:

• Your backend is Node or TypeScript and you want the most mature SDK and ecosystem for that stack.
• You need a specific channel or integration Knock supports that Notavia does not yet.
• Your team has standardized on Knock's workflow tooling and it fits how you work.
• You need something you can buy and run today.

If you are a JavaScript shop, a JavaScript-first product is the path of least resistance. Notavia's pitch is not "switch at any cost."

When Notavia fits better

• You are .NET or Blazor and want SDKs, docs, and UI that assume your stack — including a real Blazor inbox component (see the in-app inbox tutorial).
• You need white-label / OEM — your customers see your brand, not a vendor's.
• You need EU data residency (Germany) by default, or a self-host option that keeps all data inside your own infrastructure.
• You build with AI editors and want an MCP server to wire notifications up conversationally.

What it looks like in .NET

var notify = new NotifyClient("nsk_test_…");

await notify.Notifications.SendAsync(new SendRequest
{
    Channel = "email",
    Recipient = new { ExternalUserId = "u_123", Email = "ada@example.com" },
    Template = "welcome",
    Data = new { FirstName = "Ada" },
});

(Illustrative — check the current SDK reference for exact types.)

One send, typed, with retries and idempotency handled for you. The same call fans out to in-app, SMS, and chat by changing the channel.

The honest summary

If you are on Node, Knock is a strong, mature choice — evaluate it properly. If you are on .NET and you care about a native SDK, a Blazor inbox, white-label, EU residency, or self-host, that is exactly the gap Notavia was built to fill. It is free to 1,000 sends a month if you want to try it against your own stack.
