Where each one falls short

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

Apache Pulsar

  • More components than Kafka: brokers, BookKeeper and ZooKeeper each need operating
  • Correspondingly harder to run well, and the expertise is rarer than Kafka expertise
  • A much smaller ecosystem of connectors, tooling and hiring pool than Kafka
  • The architectural advantages only pay off at a scale most deployments never reach

Xlinesoft

  • The purchase includes one year of support and upgrades only; after that, newer versions require a paid upgrade
  • Multiple database connections, REST API connections and single sign-on through Active Directory, Okta or SAML are Enterprise-only, which raises the price from $599 to $999 per developer
  • Self-hosted only. Hosting, database administration, backups, runtime updates and access-control configuration remain the customer's job, as Xlinesoft's own product facts page states
  • Applications built on Microsoft Access require a Windows web server
  • PHPRunner and ASPRunner.NET are separate products with separate licences, so moving a project between PHP and .NET is not covered by one purchase

Answered from the vendors’ own pages

Apache Pulsar: Is Apache Pulsar free?

Yes, open source under the Apache Software Foundation.

Xlinesoft: How much does PHPRunner cost?

PHPRunner Professional is $599, Enterprise Edition is $999 and MultiDev Edition, which includes three Enterprise licences, is $3,599. Professional and Enterprise prices are per developer, and each purchase includes one year of email support and free upgrades.

Source
Apache Pulsar: Pulsar or Kafka?

Pulsar separates storage from compute and covers queuing and streaming in one system. Kafka has a far larger ecosystem and hiring pool. Most teams should have a specific reason before choosing Pulsar.

Xlinesoft: Which databases does PHPRunner support?

MySQL, MariaDB, Microsoft SQL Server, PostgreSQL, Oracle, Microsoft Access, IBM DB2, Informix, SQLite and ODBC-compatible databases. Using multiple database connections in one project is an Enterprise Edition feature.

Source
Apache Pulsar: Why does separated storage matter?

Brokers hold no data, so adding or replacing one requires no rebalancing, and storage can grow without adding serving capacity.

Xlinesoft: Is there a free trial?

Yes. PHPRunner can be downloaded and evaluated for 21 days, and public live demos show the generated applications, with add, edit and delete disabled.

Source
Xlinesoft: Where do PHPRunner applications run?

On your own web server. The documented options are Apache and Microsoft IIS with a compatible PHP runtime and database extensions, and a built-in web server is available for local testing. The development application itself runs on Windows, macOS and Linux.

Source
Xlinesoft: What does the Enterprise Edition add?

Multiple database and REST API connections, data encryption, and enterprise authentication including Active Directory, Okta, Azure AD, OpenID and SAML, on top of all Professional features.

Source
Xlinesoft: What is ASPRunner.NET?

Xlinesoft's equivalent builder for ASP.NET. It generates database-driven ASP.NET web applications with the same kind of forms, reports, charts, permissions and Page Designer, and is sold separately from $599.
