Features and specs

What each product offers, as listed by its team.

P
Patternizer 5 features
Sinatra.dev 6 features
  • User-Friendly Interface
    Patternizer offers an intuitive interface that makes it easy for users to create complex patterns without prior design experience. The drag-and-drop functionality and real-time preview enhance usability, making it accessible for beginners.
  • Customization Options
    The tool provides extensive customization features, allowing users to adjust various parameters such as stripe width, spacing, opacity, and color. This flexibility helps in creating unique and personalized patterns.
  • Free to Use
    Patternizer is available for free, making it an attractive option for individuals and small businesses looking for cost-effective design tools without the need for expensive software subscriptions.
  • No Software Installation Required
    As a web-based application, Patternizer can be used directly from the browser without any need for downloading or installing additional software. This enhances accessibility and convenience for users.
  • Export Options
    Patternizer allows users to export their designs in multiple formats, which can be useful for integrating patterns into various design projects or digital platforms.

Possible disadvantages

  • Limited Functionality
    While Patternizer is great for creating striped patterns, its functionality is limited compared to more comprehensive design tools. It may not be suitable for users requiring advanced design capabilities.
  • Browser Dependency
    Being a browser-based tool, its performance can vary depending on the browser and internet connection speed. Users may experience slower performance or compatibility issues on certain browsers.
  • No Offline Access
    Patternizer requires an active internet connection to function, which can be a drawback for users who need to work in environments with limited or no internet access.
  • Learning Curve for Advanced Features
    Although the basic functionalities are user-friendly, mastering the advanced customization options might require time and experimentation, which could be a hurdle for some users.
  • Linear, GitHub and Slack
    Assign a Linear issue to Sinatra, add the sinatraai label to a GitHub issue, or mention @Sinatra in a Slack channel. In Slack it works in that thread and posts its progress there.
  • Isolated sandbox per task
    Each task gets its own cloud sandbox with your repo cloned in, behind an audited egress proxy with short-lived, scoped repo tokens.
  • Tests and self-review
    It runs your test command and reviews its own diff before marking the pull request ready for you.
  • Fixes CI and review feedback
    When CI fails or a reviewer requests changes, it pushes fixes to the same branch. A human always merges.
  • Your own model access
    Runs on your Claude or ChatGPT subscription, or an Anthropic or OpenRouter API key. Sinatra never bills for model usage.
  • CLI, MCP server and API
    Start and follow tasks from your terminal (npm i -g sinatra.dev), from claude.ai, Claude Code, Cursor or ChatGPT over MCP, or from a script with the HTTP API.

Questions & Answers

As answered by people managing Patternizer and Sinatra.dev.

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, GitHub Issues or Slack who don't want another tool to learn, and who would rather run agent work on the Claude or ChatGPT 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 started with just Linear and GitHub issues (Slack, a CLI and an MCP server came later) 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 gets its own Daytona sandbox with the repository cloned in; the sandbox stops when the task goes quiet and is reused for follow-ups. Model access is bring your own: an Anthropic or OpenRouter API key, or a Claude or ChatGPT subscription connected to the workspace.

What makes your product unique?

Sinatra.dev's answer:

It runs on the model subscription you already pay for. You assign a Linear issue, label a GitHub issue or mention it in Slack, 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 ChatGPT subscription or API key. Sinatra never bills for model usage. The free plan is 1 task at a time, plus 1 queued, with no daily limit and no card. 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. Plans are one flat monthly price for the whole workspace, any number of people: Pro is $20/mo for 3 tasks at a time, plus 10 queued, and inference runs on your own Claude or ChatGPT subscription or API key, so Sinatra never bills for model usage. And it works from Linear issues, GitHub issues and Slack threads, 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, fixes failing CI, and pushes revisions when a reviewer leaves comments. To be honest about the limits, it doesn't work from Jira, and the agent never merges its own PRs, a person does that.
