What each product offers, as listed by its team.

Zeplin 5 features
Sinatra.dev 0 features
  • Ease of Collaboration
    Zeplin facilitates seamless collaboration between designers and developers by providing a shared space where they can access design specifications, assets, and resources.
  • Design Consistency
    By offering detailed design specifications and exportable assets, Zeplin ensures consistency across different development platforms and helps maintain a unified design system.
  • Automated Asset Export
    Zeplin automatically generates assets in various formats and resolutions, which saves time and reduces the likelihood of errors during the handoff process.
  • Integration with Design Tools
    Zeplin integrates seamlessly with popular design tools like Sketch, Adobe XD, Figma, and Photoshop, making it easy for designers to upload and manage their projects.
  • Version Control
    The platform offers version control for design projects, enabling teams to track changes, revert to previous versions, and ensure they're always working with the most up-to-date designs.

Possible disadvantages

  • Pricing
    Zeplin's subscription model can be costly for smaller teams or individual freelancers, especially when compared to other design handoff tools available in the market.
  • Limited Prototyping Features
    Unlike some other design collaboration tools, Zeplin lacks advanced prototyping features, which might necessitate the use of additional tools for complete design validation.
  • Learning Curve
    New users may require some time to learn Zeplin’s interface and features, which could be a challenge for teams that need to quickly onboard and get up to speed.
  • Dependency on Design Tools
    Zeplin relies heavily on imported designs from other tools rather than allowing for direct design creation within its platform. This dependency could be a limitation for teams looking for an all-in-one solution.
  • Limited Free Tier
    The free version of Zeplin is quite limited in terms of the number of projects and collaborators, which might not be sufficient for larger teams or complex projects.

Questions & Answers

As answered by people managing Zeplin and Sinatra.dev.

What makes your product unique?

Sinatra.dev's answer:

It runs on the model subscription you already pay for. You assign a Linear issue or label a GitHub issue, the agent does the work in its own isolated sandbox and comes back with a pull request, and the model bill goes to your own Claude or Codex subscription or API key. We don't resell tokens or mark them up. The free tier is 5 tasks a day on your own credentials, every day, or 1 task a day where Sinatra covers the tokens. Pricing was the reason we built it in the first place, the agents we tried billed in credits you couldn't predict.

Why should a person choose your product over its competitors?

Sinatra.dev's answer:

Pricing and entry points. The paid plan is $20 per member per month for the hosted sandboxes and orchestration, with no markup on tokens because inference runs on your own Claude or Codex subscription or API key. And it works from Linear issues as well as GitHub, so a team whose tickets live in Linear can assign work to the agent the way they'd assign a teammate. It also reviews its own diff and posts the findings on the PR, and pushes revisions when a reviewer leaves comments. To be honest about the limits, it only works from GitHub and Linear issues today, and the agent never merges its own PRs, a person does that.

How would you describe the primary audience of your product?

Sinatra.dev's answer:

Small engineering teams and solo founders with a backlog of well specified tickets they never get to: reproducible bugs, small features with acceptance criteria, the work that is clear enough to hand off but keeps getting pushed behind bigger things. Teams already working out of Linear or GitHub Issues who don't want another tool to learn, and who would rather run agent work on the Claude or Codex subscription they already have than open a new metered account somewhere else.

What's the story behind your product?

Sinatra.dev's answer:

I built a pet sitting marketplace with my wife. She always had features she wanted shipped and every one of them went through me, so I spent about three months building an agent she could assign tickets to instead. She writes the ticket, assigns it, and a PR comes back. She's now a big contributor to that codebase without me being in the way. I started handing it my own backlog too and eventually it turned into a product. It has been a lot harder to build than I expected, lots of edge cases, which is why it only works from Linear and GitHub issues right now and why the agent doesn't merge its own PRs, you still do that last part yourself.

Which are the primary technologies used for building your product?

Sinatra.dev's answer:

TypeScript throughout. A Fastify API for webhooks and OAuth, a Temporal worker that orchestrates each agent run, Next.js for the dashboard and the site, and Prisma on Postgres. Every task runs in its own Daytona sandbox that gets cloned, worked and torn down. Model access is bring your own: an Anthropic or OpenRouter API key, or a Claude or ChatGPT subscription connected to the workspace.
