Possible disadvantages

  • Limited Free Version
    The free version of Mentimeter offers only a limited number of questions and features, which may not be sufficient for all users.
  • Costly Premium Plans
    Premium plans can be expensive, especially for small businesses or educational institutions with limited budgets.
  • Internet Dependency
    Mentimeter requires a stable internet connection, which can be a limitation in areas with unreliable connectivity.
  • Customization Constraints
    While the platform offers multiple templates, the extent of customization in terms of design and layout is somewhat limited compared to some competitors.
  • Learning Curve for Advanced Features
    Although basic functionalities are user-friendly, mastering advanced features and integrations may require additional time and effort.
  • 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 Mentimeter 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 agent at a time, plus 1 waiting, 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 agents at a time, plus 10 waiting, agents work until they're done, 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.
