If you want to try out Open SWE, but aren’t sure where to start, here are a few example tasks you can try out.
1

Clone the TypeScript template

The examples below are all for TypeScript tasks. For these, you should clone an empty TypeScript template repository:bracesproul/typescript-templateVisit the GitHub UI, and click Use this template to create a new repository based on this template.

Give Open SWE access to your repository

If you did not give Open SWE to all of your repositories when setting it up the first time, you’ll need to give Open SWE access to this repository.
  1. Visit the settings page on Open SWE: swe.langchain.com/settings
  2. To the right of your user inside the Current User section, click the + button. This will redirect you to GitHub where you can authorize Open SWE to access your repositories.
  3. Select the new TypeScript template you just created.
Once done, it will redirect you back to Open SWE. Once here, find the new repository under the repo dropdown above the chat input.

Submit one of the example tasks

After cloning the template and giving Open SWE access to it, you can submit one of the example tasks!
Below are a series of examples you can try out: 
Create an Express-based API exposing CRUD endpoints for `/books`.
Include request validation with `zod`, proper HTTP status codes, and an
in-memory repository layer that can later be swapped for a database. Add Jest
tests covering happy-path and a 'missing ISBN' error case.

Add a small WebSocket server (using `ws`) that tracks how many clients
are currently connected and broadcasts the updated count every 5 seconds.
Expose a health-check HTTP route returning the same value for monitoring
tools. Provide a minimal HTML demo page that shows the live number.

Implement a CLI (`src/sync-issues.ts`) that reads a `config.json` with
one or more GitHub repos, fetches their open issues via the GitHub REST API,
and writes a local `issues.{owner}.{repo}.csv`. Use `yargs` for parsing and
include a `--since YYYY-MM-DD` flag to filter by creation date.

Build a middleware that issues short-lived access tokens and long-lived
refresh tokens. Store refresh tokens in a signed, HttpOnly cookie and expose
`/auth/refresh` to rotate them. Protect a sample route (`/profile`) and supply
Postman collections for login and refresh flows.

Design a generic cache interface with `get`, `set`, and `invalidate`
methods, then provide two adapters: an in-memory `Map` implementation and a
Redis adapter (mock Redis with `ioredis-mock` for tests). Demonstrate
hot-swapping the adapter via an environment variable without code changes.

Stand up an Apollo Server that federates data from the public
JSONPlaceholder `/users` and `/posts` endpoints. Expose a `user(id)` query
returning the user plus their posts in a single round-trip. Add schema-driven
TypeScript types (`codegen.yml`) and example queries in `README.md`.

Create an endpoint that returns a time-limited pre-signed PUT URL for
an S3 bucket (use `@aws-sdk/client-s3`). Include a small React demo (Vite)
that lets a user pick an image and upload it directly. Validate MIME type on
the server before signing.

Publish an internal `/src/date` module that formats, parses, and
time-zone-converts dates using `luxon`. Support at least 'en-US', 'de-DE', and
'ja-JP'. Provide type-safe wrappers, exhaustive unit tests, and a benchmark
script comparing it to native `Intl.DateTimeFormat`.
