 # Welcome to DBOS!
 
 DBOS is a serverless platform that radically simplifies backend application development.
 
-- **Build with DBOS Transact** - An [open-source TypeScript framework](https://github.com/dbos-inc/dbos-ts) for backend applications.
+- **Build with DBOS Transact** - An open-source framework for building resilient backend applications in [TypeScript](https://github.com/dbos-inc/dbos-transact) or [Python](https://www.dbos.dev/dbos-transact-python).
 
-- **Deploy to DBOS Cloud** - A [seriously fast](https://www.dbos.dev/blog/dbos-vs-aws-step-functions-benchmark) serverless hosting platform for TypeScript backends.
+- **Deploy to DBOS Cloud** - A [seriously fast](https://www.dbos.dev/blog/dbos-vs-aws-step-functions-benchmark) serverless hosting platform for backend applications.
 
 Build your next application with DBOS because you want:
 
 - **Blazing-fast, developer-friendly serverless**.  Develop your project locally and run it anywhere. When you're ready, [deploy it for free to DBOS Cloud](./getting-started/quickstart#deploy-your-first-app-to-the-cloud) and experience serverless hosting [25x faster](https://www.dbos.dev/blog/dbos-vs-aws-step-functions-benchmark) and [15x cheaper](https://www.dbos.dev/blog/dbos-vs-lambda-cost) than AWS Lambda.
 - **Resilience to any failure**.  If your app is interrupted for any reason, it [automatically resumes from where it left off](./tutorials/workflow-tutorial#reliability-guarantees).  Reliable message delivery is [built in](./tutorials/workflow-communication-tutorial#reliability-guarantees-1). Idempotency is [built in](./tutorials/idempotency-tutorial).
 - **Built-in observability**. Automatically emit [OpenTelemetry](https://opentelemetry.io/)-compatible [logs and traces](https://docs.dbos.dev/tutorials/logging) from any application. Query your app's history from the [command line](https://docs.dbos.dev/api-reference/cli#workflow-management-commands) or [with SQL](https://docs.dbos.dev/api-reference/system-tables).
 - **Database time travel**. Query your database as of [any past point in time](./cloud-tutorials/interactive-timetravel.md). Use [time travel debugging](./cloud-tutorials/timetravel-debugging.md) to replay production traces locally.
-- **A framework built for the tools you love**. Build with TypeScript and **any** PostgreSQL-compatible database. Use raw SQL or your favorite query builder or ORM—we support [Knex](./tutorials/using-knex.md), [Drizzle](./tutorials/using-drizzle.md) [TypeORM](./tutorials/using-typeorm.md), and [Prisma](./tutorials/using-prisma.md) out of the box.
