The short version

  • Only Apache Kafka has a free tier, so it costs nothing to try first.
  • Each has a real cost: Apache Kafka operationally heavy to self-host: brokers, storage, rebalancing and upgrades are a standing job, which is why managed Kafka is a large market; Erply priced per store per month rather than a flat company rate, starting at $49/store for the Giftshop & Grocery Chain plan with only 1 user account and 1 POS terminal included

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Apache Kafka

  • Operationally heavy to self-host: brokers, storage, rebalancing and upgrades are a standing job, which is why managed Kafka is a large market
  • Overkill for straightforward job queues, where a simpler broker is easier to run and reason about
  • Ordering guarantees hold per partition, not per topic, and getting partitioning wrong is a common and expensive design mistake
  • The ecosystem is fragmented across the Apache project and vendor distributions, so documentation and tooling advice often assume a particular distribution

Erply

  • Priced per store per month rather than a flat company rate, starting at $49/store for the Giftshop & Grocery Chain plan with only 1 user account and 1 POS terminal included
  • Multichannel Chains plan is limited to 2 user accounts at $179/store per month
  • POS for NetSuite starts at $1,800 per month and Franchise & Chain starts at $3,500 per month, both quote-adjusted from there
  • Cancellation requires a written request 30 days prior to the end of the billing cycle

Answered from the vendors’ own pages

Apache Kafka: Is Apache Kafka free?

Yes. Kafka is open source under the Apache License v2 with no licence fee. Costs come from the infrastructure you run it on, or from a managed service such as Confluent Cloud.

Erply: What payment options does Erply offer?

Erply offers both monthly and annual billing contracts. Payment is due in advance at the start of each billing cycle. Annual contracts receive discounts compared to monthly rates. Changes to payment take effect within 48 hours.

Source
Apache Kafka: How is Kafka different from a message queue?

A queue usually removes a message once it is consumed. Kafka keeps an ordered, durable log, so consumers track their own position and history can be replayed — which is what makes rebuilding state after a bug possible.

Erply: Is there a free trial for Erply?

Erply offers free account creation with no credit card required to explore the platform. Users can create an account and test the service before committing to a paid plan.

Source
Apache Kafka: Who uses Kafka?

The project reports use by more than 80% of the Fortune 100, with over 5 million lifetime downloads.

Erply: Can I cancel my Erply subscription?

Erply subscriptions can be cancelled, but require a written request submitted at least 30 days prior to the desired cancellation date.

Source
Apache Kafka: Do I need to run Kafka myself?

No. Self-hosting is the operationally expensive option; managed services such as Confluent Cloud run the brokers for you and bill on throughput and storage instead.
