Sinatra is a background coding agent for teams on Linear, GitHub and Slack. Assign a Linear issue to Sinatra, add the sinatraai label to a GitHub issue, or mention @Sinatra in a Slack thread, and it works the request in an isolated cloud sandbox: it reads the code, writes the change, runs your...

Features and specs

What each product offers, as listed by its team.

Moment Timezone 4 features
Sinatra.dev 6 features
  • Extensive Timezone Support
    Moment Timezone provides a comprehensive database of over 400 time zones, derived from the IANA Time Zone Database, allowing accurate conversions and calculations across different time zones.
  • Ease of Use
    The library extends the functionality of Moment.js, making it straightforward to integrate with existing Moment.js code and manage date and time manipulations with additional timezone support.
  • Active Community and Documentation
    There is a strong community of developers using Moment Timezone, and it comes with thorough documentation which helps in resolving common issues and implementing features efficiently.
  • Consistent Updates
    Regular updates ensure that Moment Timezone stays current with the latest changes in time zone rules as published by IANA.

Possible disadvantages

  • Large Library Size
    Moment and Moment Timezone can add significant weight to your JavaScript bundle, which might be an issue for performance-sensitive applications, especially when alternatives like date-fns or Luxon offer smaller footprints.
  • Mutability
    Moment and by extension Moment Timezone utilizes mutable objects which can lead to bugs if not handled carefully, unlike modern JS libraries that use immutable date objects.
  • Deprecated Status
    Moment.js and Moment Timezone are in maintenance mode, meaning no new features are being developed, which might discourage use in new projects in favor of more modern libraries.
  • Learning Curve for Newbies
    Existing users of Moment might find it easier to use the timezone features, but new developers might face an initial learning curve given the variety of functions and the library's large API surface.
  • 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 Moment Timezone 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.

  • Working with timezone naive date objects.
    Moment-timezone is pretty great. However the moment library is no longer maintained, and there's some complications to its use due to it being mutable. Still works great though. Source: about 4 years ago
  • How to make an event website with Eui
    It was actually much easier to make than I thought it would be, thanks to Moment. - Source: dev.to / about 4 years ago
  • Build Instructions for your own WSB 3000
    The clock is in Javascript. Time zones in JavaScript historically are non-trivial since everything is based on the client clocktime. Fortunately, there is moment.js and moment-timezone-with-data.js that vastly simplify getting the... Source: about 5 years ago
