  • Documentation
    Users have reported that the documentation can sometimes be lacking in detail or difficult to navigate.
  • Cost
    While Fly.io offers a free tier, the cost can become significant as you scale your applications.
  • Limited Language Support
    Fly.io supports fewer runtime environments and languages compared to more established platforms like AWS or Azure.
  • Platform Maturity
    As a relatively new platform, Fly.io may lack some advanced features and ecosystem integrations offered by more mature competitors.
  • Debugging
    The debugging tools and processes can be less comprehensive compared to traditional cloud providers.

ZenStack features and specs

  • Streamlined Development
    ZenStack simplifies application development by integrating database design with backend API generation, reducing the need for boilerplate code and speeding up the development process.
  • Consistency Between Models and APIs
    By defining models in a single place, ZenStack ensures that database schemas and APIs remain consistent, minimizing the risk of discrepancies between them.
  • Type Safety
    ZenStack enhances type safety, especially when used with TypeScript, by providing clear type definitions that can help catch errors early in the development process.
  • Open Source
    Being open source, ZenStack allows developers to inspect, modify, and contribute to the codebase, fostering a community-driven approach to its evolution.

Possible disadvantages of ZenStack

  • Learning Curve
    For developers who are not familiar with the concept of integrating database design with API generation, there might be an initial learning curve to fully leverage ZenStack's capabilities.
  • Limited Customization
    While ZenStack offers a streamlined approach to development, it may limit some advanced customization options that developers are accustomed to when manually coding APIs and database interactions.
  • Community and Support
    Given its relative newness, ZenStack may not have as large of a community or as many resources compared to more established frameworks, potentially leading to challenges in finding solutions or examples.
  • Integration Challenges
    Depending on the existing technology stack, integrating ZenStack might present challenges if it doesn't completely align with other tools or workflows being used.

  • Best alternatives to Heroku in 2026
    Fly.io opens up two things Heroku keeps at arm's length: real multi-region deployment and full control over the runtime. Heroku's Common Runtime offers two regions (US and EU), and Private Spaces gets you one region at a time from a wider list. Fly runs Firecracker microVMs across eighteen regions on six continents, and replicas can be pinned to specific cities. If your Heroku app has global users and you've been... - Source: dev.to / about 2 months ago

    The gateway is the web service that receives requests. I host it on Fly. It accepts Slack events, automation API calls, trigger requests, Composio webhooks, Inngest calls, and runtime calls. - Source: dev.to / 3 months ago
  • It Worked on My Machine (Literally)
    The tunnel was never meant to be permanent (it runs off my laptop, and the URL changes every time it restarts), so the next step was deploying somewhere real. I built the Docker image for Fly.io, set my username, and shipped it. - Source: dev.to / 3 months ago

  • Prisma vs Drizzle vs ZenStack: Choosing a TypeScript ORM in 2026
    But the TypeScript ORM space has quietly matured. Drizzle emerged as a serious alternative for developers who felt Prisma was too opinionated. And ZenStack v3 just completed a full rewrite that positions it not just as an ORM, but as a full-stack data layer. - Source: dev.to / 5 months ago
  • Your Stack Choice Is Coding Agent's Safety Net
    ZenStack is a TypeScript toolkit centered around a (Prisma-like) schema language called ZModel. In ZModel, you define your data model, access control rules, and validation constraints in a single file:. - Source: dev.to / 6 months ago
  • What would a "permissions-first ORM" look like? Looking for spec feedback
    I haven't read through the entire thing yet, but looks conceptually similar to Zenstack (https://zenstack.dev) with the auth plugin and auto-generated APIs, so I'd be interested in a comparison with that. Fwiw, I went down the path of trying to do something similar with Drizzle and gave up since it was in such a state of flux (this was last year). There are (were) a ton of edge cases around trying to add automatic... - Source: Hacker News / 7 months ago
