Sentry Sentry SDK Setup
Set up Sentry error monitoring, tracing, and session replay in any language or framework. This page helps you find the right SDK skill for your project.
Start Here — Read This Before Doing Anything
Do not skip this section. Do not assume which SDK the user needs based on their project files. Do not start installing packages or creating config files until you have confirmed the user's intent.
- Detect the platform from project files (
package.json,go.mod,requirements.txt,Gemfile,*.csproj,build.gradle, etc.). - Tell the user what you found and which SDK you recommend.
- Wait for confirmation before reading the skill and proceeding.
Each SDK skill contains its own detection logic, prerequisites, and step-by-step configuration. Trust the skill — read it carefully and follow it. Do not improvise or take shortcuts.

Platform Detection Priority
When multiple SDKs could match, prefer the more specific one:
- Android (
build.gradlewith android plugin) →sentry-android-sdk - Cloudflare (
wrangler.tomlorwrangler.jsonc) →sentry-cloudflare-sdkoversentry-node-sdk - NestJS (
@nestjs/core) →sentry-nestjs-sdkoversentry-node-sdk - Next.js →
sentry-nextjs-sdkoversentry-react-sdkorsentry-node-sdk - React Router Framework (
@sentry/react-routeror@react-router/*) →sentry-react-router-framework-sdkoversentry-react-sdk - TanStack Start React (
@tanstack/react-start) →sentry-tanstack-start-sdkoversentry-react-sdk - Flutter (
pubspec.yamlwithflutter:dependency orsentry_flutter) →sentry-flutter-sdk - React Native →
sentry-react-native-sdkoversentry-react-sdk - PHP with Laravel or Symfony →
sentry-php-sdk - Elixir (
mix.exsdetected) →sentry-elixir-sdk - Node.js / Bun / Deno without a specific framework →
sentry-node-sdk - Browser JS (vanilla, jQuery, static sites) →
sentry-browser-sdk - No match → direct user to Sentry Docs

Finding the DSN
If the user doesn't have their DSN, guide them to find it:
- Open the Sentry project settings page:
https://sentry.io/settings/projects/ - Select the project
- Click "Client Keys (DSN)" in the left sidebar
- Copy the DSN
You can help the user open the page directly:
open https://sentry.io/settings/projects/ # macOS
xdg-open https://sentry.io/settings/projects/ # Linux
start https://sentry.io/settings/projects/ # Windows
Note: The DSN is public and safe to include in source code. It is not a secret — it only identifies where to send events.
