Is Firestore or RabbitMQ better?

Neither clearly leads. Firestore starts at Free and RabbitMQ at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Firestore or RabbitMQ?

Firestore starts at Free and RabbitMQ at Free.

Does Firestore or RabbitMQ run on more platforms?

Firestore runs on Web, Ios, Android, Flutter. RabbitMQ runs on Linux, macOS, Windows, Docker, Kubernetes.

Can I use Firestore for free?

Both have a free tier, so you can try either at no cost before committing.

What is Firestore best used for?

Firestore is most often used for storing structured application data with realtime listeners, backing mobile and web apps with a serverless document database, building offline first apps that sync when connectivity returns. Of those, storing structured application data with realtime listeners and backing mobile and web apps with a serverless document database are not what RabbitMQ is typically brought in for.

What can Firestore do that RabbitMQ cannot?

Firestore covers Document Model, Real-time Updates, Offline Support, ACID Transactions. RabbitMQ covers Flexible routing, Multiple protocols, Management UI, Clustering and mirroring.

The short version

Each has a real cost: Firestore the no-cost Spark plan caps Standard edition at 50,000 document reads, 20,000 writes and 20,000 deletes per day; RabbitMQ not built for replay: once consumed, a message is gone, which is exactly what Kafka exists to change
They diverge on capability: Firestore covers Document Model, RabbitMQ covers Flexible routing.

Where each one falls short

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

Firestore

The no-cost Spark plan caps Standard edition at 50,000 document reads, 20,000 writes and 20,000 deletes per day
The Spark plan caps storage at 1 GiB and network egress at 10 GiB per month
Charging is per document read, so a query returning many documents bills for every one of them
Going beyond the free thresholds requires the pay as you go Blaze plan billed at Google Cloud rates with no fixed monthly ceiling

RabbitMQ

Not built for replay: once consumed, a message is gone, which is exactly what Kafka exists to change
Throughput ceilings are lower than a log-based platform under very heavy streaming loads
Queues that build up degrade broker performance, so consumer lag is an operational problem rather than just a backlog
Clustering and partition behaviour has historically been a source of hard-to-diagnose problems

Answered from the vendors’ own pages

Firestore: What are the free limits on Cloud Firestore?

The Spark Plan includes 1 GiB of stored data, 50,000 reads per day, 20,000 writes per day, and 20,000 deletes per day at no cost.

Source

RabbitMQ: Is RabbitMQ free?

Yes, open source with no licence fee. Broadcom sells commercial support.

Firestore: What happens when I exceed the Spark Plan free tier?

Exceeding the free tier requires upgrading to the Blaze Plan, which bills based on actual usage through Google Cloud pricing. Charges apply for reads, writes, deletes, and data storage.

Source

RabbitMQ: RabbitMQ or Kafka?

RabbitMQ is a message broker: simpler to run and better at flexible routing and work queues. Kafka is a replayable event log built for very high throughput streaming, and much heavier to operate.

Firestore: Can I use Firestore without a credit card?

Yes, you can use the Spark Plan indefinitely without a credit card. To use the Blaze Plan (pay-as-you-go), a credit card is required.

Source

RabbitMQ: Can RabbitMQ replay messages?

Not in the way Kafka can. Messages are removed once acknowledged, so rebuilding state from history is not the model.

Firestore: Is there a trial period for Cloud Firestore?

No trial period is specified. The Spark Plan free tier serves as the trial, with no time limit.
