Prompt it, Publish it - AI-built works from your .NET APIs

AI Chat puts a ChatGPT-like assistant inside your .NET App, where it calls the APIs the signed-in user is allowed to call and turns the results into interactive views and reports your team can explore, review and publish

Multitenancy that can't be forgotten

ServiceStack v10.4 moves tenant isolation from every query to the database connection, with OrmLite connection filters and write rules that confine selects, updates, deletes, inserts and AutoQuery APIs to the request's tenant, fail closed until it's known, and record trusted audit columns on every write

Follow every request with OpenTelemetry

ServiceStack v10.3 emits standard OpenTelemetry traces and metrics that follow a request from its API call through outbound HTTP calls, MQ messages and Background Jobs, even across servers, in Jaeger, Grafana Tempo, Honeycomb, Datadog or the .NET Aspire Dashboard

API Rate Limiting

ServiceStack v10.3 adds opt-in ASP.NET Core rate limiting for ServiceStack APIs - bind a named policy to a Request DTO or share one budget across every API with the same Tag, enforced across every route an API can be called from

Startup Tasks - Generate code from your running App

StartupTasks run dev-time tasks once your App has fully started, keeping client DTOs and other generated code in sync with your server on every restart, with no extra build step for developers or AI Assistants to remember
