Features and specs

What each product offers, as listed by its team.

KiTTY 5 features
Sinatra.dev 6 features
  • Enhanced Features
    KiTTY offers more features than PuTTY, including additional options such as automatic password saving, session filtering, and session launcher, enhancing user experience and productivity.
  • Portability
    The tool is available in a portable version, which does not require installation. This makes it convenient for use on different machines without needing administrator permissions.
  • Customization
    KiTTY supports a variety of customization options, such as configurable shortcuts, transparency options, and built-in chat functionalities, allowing users to tailor the terminal emulator to their specific needs.
  • Integration with Windows
    KiTTY integrates well with Windows, offering features like the ability to create desktop shortcuts for sessions and support for Windows jump lists.
  • Scripting Capabilities
    KiTTY allows the automation of tasks through its scripting capabilities, making it easier for users to perform repetitive tasks efficiently.

Possible disadvantages

  • Windows-Only
    KiTTY is designed primarily for Windows, which limits its usability for users on other operating systems such as macOS or Linux.
  • Steeper Learning Curve
    The additional features and options may result in a steeper learning curve for new users who are accustomed to simpler tools.
  • Stability Issues
    Some users may encounter stability issues or bugs, which could affect reliability during critical tasks.
  • Less Frequent Updates
    Compared to some other terminal emulators, KiTTY does not receive updates as frequently, which may lead to slower implementation of new features or security fixes.
  • Security Concerns
    Automatically saving passwords can introduce security risks if the local machine is compromised, as stored credentials could become accessible to unauthorized 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 KiTTY 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.
