The short version
- Only Jitsu has a free tier, so it costs nothing to try first.
- Each has a real cost: Cortex pricing is quote only, so a platform team cannot build a business case or compare against the true cost of self-hosted Backstage without entering a sales cycle first.; Jitsu jitsu is a pipeline, not a customer data platform, so identity resolution, audience building and reverse ETL are absent and a marketing team expecting Segment parity will be disappointed.
- They diverge on capability: Cortex covers Service catalogue, Jitsu covers Event collection.

What people use each for
The jobs each tool is most often brought in to do.
Cortex
- A platform team that needs to prove to leadership how far a Kubernetes or framework migration has actually progressed across hundreds of servicesnot Jitsu
- An organisation where ownership of production services is genuinely unknown after reorganisations or acquisitionsnot Jitsu
- Enforcing production readiness standards on new services at creation time rather than at incident reviewnot Jitsu
- Replacing a self-hosted Backstage that is consuming a full-time engineer or two just to stay upgradednot Jitsu
Jitsu
- A team paying five figures a year to a customer data platform when all it actually does is send events to Snowflakenot Cortex
- An engineering group that needs event collection running inside its own VPC for data residency or security review reasonsnot Cortex
- A product analytics setup that wants raw events in the warehouse as the source of truth rather than trapped in a vendor toolnot Cortex
- A startup that needs first-party event collection on its own domain to reduce loss from tracker blocking without paying CDP pricesnot Cortex
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Cortex
- Pricing is quote only, so a platform team cannot build a business case or compare against the true cost of self-hosted Backstage without entering a sales cycle first.
- The catalogue is only as accurate as the metadata you supply, so an organisation with inconsistent repository conventions spends its first quarter cleaning data before any scorecard means anything.
- Scorecards create political friction: publishing a per-team grade turns an engineering standard into a performance metric, and teams will game the rules rather than fix the underlying issue.
- It is closed source and hosted, so organisations with strict data residency or air-gap requirements have limited options compared with running Backstage themselves.
- Value scales with organisation size, so a company with fifty engineers and thirty services will find the catalogue tells them nothing they did not already know while still paying an enterprise contract.
Jitsu
- Jitsu is a pipeline, not a customer data platform, so identity resolution, audience building and reverse ETL are absent and a marketing team expecting Segment parity will be disappointed.
- Connector sync frequency is deliberately tiered, with the free plan limited to manual runs and one daily sync, so anything approaching operational freshness requires the paid plan or self-hosting.
- Self-hosting means you own the reliability of a system that drops data silently when misconfigured, and event loss is uniquely hard to notice because nothing errors, the numbers are just quietly lower.
- The connector catalogue is far smaller than Fivetran or Airbyte, so if your requirement is pulling from many SaaS sources rather than pushing events, Jitsu is the wrong half of the problem.
- It is a small company with a small commercial team, so enterprise procurement processes around security review, contractual SLAs and support escalation take longer than with an incumbent vendor.

Questions people ask
- Is Cortex or Jitsu better?
- Neither clearly leads. Cortex starts at On request and Jitsu at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Cortex or Jitsu?
- Jitsu has a free tier; the other does not. Paid plans start at On request for Cortex and Free for Jitsu.
- Does Cortex or Jitsu run on more platforms?
- Cortex runs on Web, API. Jitsu runs on Web, Linux, Docker, Kubernetes, iOS, Android.
- Can I use Jitsu for free?
- Yes. Jitsu has a free tier, so you can try it without paying. Cortex starts at On request.
- What is Cortex best used for?
- Cortex is most often used for a platform team that needs to prove to leadership how far a kubernetes or framework migration has actually progressed across hundreds of services, an organisation where ownership of production services is genuinely unknown after reorganisations or acquisitions, enforcing production readiness standards on new services at creation time rather than at incident review, replacing a self-hosted backstage that is consuming a full-time engineer or two just to stay upgraded. Of those, a platform team that needs to prove to leadership how far a kubernetes or framework migration has actually progressed across hundreds of services and an organisation where ownership of production services is genuinely unknown after reorganisations or acquisitions are not what Jitsu is typically brought in for.
- What can Cortex do that Jitsu cannot?
- Cortex covers Service catalogue, Scorecards, Initiatives, Self-service templates. Jitsu covers Event collection, Warehouse destinations, Connector syncs, Transformations.
Answered from the vendors’ own pages
Cortex: How is Cortex different from Backstage?
Backstage is an open source framework you build and staff. Cortex is a hosted product with scorecards and initiatives out of the box and no platform team required to keep it running.
Jitsu: Is Jitsu the same as Jitsi?
No. Jitsu is an open source event data pipeline. Jitsi is an unrelated video conferencing project.
Cortex: Is pricing published?
No. Cortex requires a sales conversation and prepares a custom proposal.
Jitsu: Can I self-host for free?
Yes. The project is MIT licensed with no usage limits when self-hosted.
Cortex: Can it self-host?
It is offered as a hosted product; on-premise arrangements are handled through sales rather than published.
Jitsu: How does the cost compare with Segment?
The Business plan is 99 US dollars a month for two million active events, where a per-tracked-user CDP typically costs orders of magnitude more at comparable volume.
Cortex: What is the main adoption risk?
Bad or missing service metadata. The catalogue and every scorecard on top of it inherit whatever quality your repositories already have.
Jitsu: Does Jitsu do identity resolution?
No. It transports and transforms events; identity stitching and audiences are not part of the product.
