    Due to its modular and extensible nature, Apache Karaf can have a steeper learning curve for new users, especially those unfamiliar with OSGi concepts and enterprise middleware.
  • Resource intensity
    Running and managing an Apache Karaf instance can be resource-intensive, especially when dealing with large-scale or highly modular applications. Adequate memory and processing power are required to maintain optimal performance.
  • Complex deployment
    While Karaf can handle complex deployment scenarios, setting it up and configuring it properly can be more involved compared to other simpler solutions. This complexity can increase the initial setup time and effort.
  • Limited community support
    Despite being an Apache project, the community around Apache Karaf might not be as large or active as other popular frameworks, potentially making it harder to find ample resources or immediate support.
  • Dependency management challenges
    Managing dependencies in Karaf, especially when dealing with multiple third-party libraries and their versions, can become cumbersome and lead to conflicts if not handled carefully.

  • Need advice: Java Software Architecture for SaaS startup doing CRUD and REST APIs?
    Apache Karaf with OSGi works pretty nice using annotation based dependency injection with the declarative services, removing the need to mess with those hopefully archaic XML blueprints. Too bad it's not as trendy as spring and the developers so many of the tutorials can be a bit dated and hard to find. Karaf also supports many other frameworks and programming models as well and there's even Red Hat supported... Source: about 5 years ago

  • Ask HN: What Are You Working On? (February 2026)
    Https://stacktape.com An alternative to tools lik sst.dev or serverless framework, or a PaaS services like Render.com or Flightcontrol. Deploys to user's own AWS. IaC-first. Has a PaaS-like console UI. The best features: auto-generates IaC config by scanning your code. Has built-in EC2 runner which is 2-6x faster than AWS CodeBuild. We've now also implemented dev mode, which is similar to SST. It deploys parts of... - Source: Hacker News / 5 months ago
  • Ask HN: What Are You Working On? (June 2025)
    v3 of https://stacktape.com Stacktape is a PaaS that deploy to user's own AWS account. V3 adds many new features, but namely the ability to generate IaC config directly from code, by analyzing the user's repository (both deterministically and using multiple AI techniques). For example, if it assumes your application is a Web API that uses Postgres and Redis, it will create a Stacktape IaC config that deploys... - Source: Hacker News / about 1 year ago

    At https://stacktape.com, we're also in the same space. We're offering Heroku-like experience on top of your own AWS account. I like what you're doing. But, to behonst, it's a tough market. While the promise of $265 vs $4 might seem like a no-brainer, you're comparing apples to oranges. - Your DX is most likely be far from Heroku's.

  • Heroku Is Down
    For those interested in a Heroku alternative, have a look at https://stacktape.com (full disclosure: I'm a founder). It's a Heroku-like PaaS platform that deploys directly to your own AWS account. It support both serverless (lambda functions), and serverful (AWS ECS Fargate or EC2) deployments. Besides that, it supports other AWS infrastructure resources, such as RDS, Aurora, Redis, ElasticSearch, etc.. You can... - Source: Hacker News / about 1 year ago
  • Coolify: Open-source and self-hostable Heroku / Netlify / Vercel alternative
    I'm sorry for being a bit off-topic, but I'm a founder of a PaaS company myself, and I think that what we offer is a great alternative to Coolify for companies that need a more "managed" and reliable infra. https://stacktape.com is a Heroku/Vercel-like PaaS platform that deploys directly to your own AWS account.
