SendItWhenever vs AWS EventBridge Scheduler: a simpler webhook scheduler

Looking for an AWS EventBridge alternative without IAM roles and API destinations? EventBridge Scheduler is powerful and deeply integrated with AWS — but pointing it at your own HTTPS endpoint means standing up connections, API destinations, and IAM policies. SendItWhenever is a flat-rate webhook scheduler built for that gap: three lines of SDK, any HTTPS URL, and a flat $19/month.

Setup: three lines vs IAM and API destinations

The biggest difference is operational. To deliver a scheduled HTTP request with EventBridge Scheduler, you configure an API destination, a connection with auth, and an IAM role granting the scheduler permission to invoke it. With SendItWhenever you install @sendithq/sdk, construct the client with one API key, and call schedule() — no AWS account required.

Cost: flat vs pay-per-use

EventBridge Scheduler bills per use under AWS pricing, which can be very economical at high volume. SendItWhenever is a flat $19/month with no per-invocation metering — the trade is predictability and simplicity over raw at-scale unit cost. For indie budgets, a flat invoice removes the biggest billing risk.

Security & reliability

Every outgoing webhook is signed with an HMAC header, payloads are encrypted at rest with AES-256-GCM and decrypted only in memory at fire time, and SSRF protection re-resolves DNS just before firing to block private and metadata ranges. Failed deliveries retry up to five times with exponential backoff before isolation in a Dead Letter Queue — all visible in a built-in delivery log rather than CloudWatch.

When EventBridge is the better choice

If you already run on AWS, target AWS services natively (Lambda, SQS, Step Functions), or operate at a scale where pay-per-use is cheaper than a flat rate, EventBridge Scheduler is likely the better fit. SendItWhenever is focused on indie hackers and small SaaS who want a dependable webhook scheduler without AWS overhead.

FAQ

Is SendItWhenever an AWS EventBridge alternative?

For the common case — scheduling a delayed HTTP webhook to your own endpoint — yes. SendItWhenever skips IAM roles, API destinations, and connections: install the SDK, call schedule(), and the webhook fires at the set time. EventBridge Scheduler is a better fit when you target AWS services natively or run at very high volume.

Do I need an AWS account?

No. SendItWhenever is a standalone service — no AWS account, IAM policy, VPC, or API destination configuration. You only need a Node project and one API key.

How is delivery secured?

Every outgoing webhook carries an HMAC signature you can verify in one line. Payloads are encrypted at rest with AES-256-GCM, SSRF protection is always on, and failed deliveries retry up to five times before moving to a Dead Letter Queue.
