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.

How to Fetch Skills

Use curl to download skills — they are 10–20 KB files that fetch tools often summarize, losing critical details.

curl -sL https://skills.sentry.dev/sentry-nextjs-sdk/SKILL.md

Append the path from the Path column in the table below to https://skills.sentry.dev/. Do not guess or shorten URLs.

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.

1. Detect the platform from project files (package.json, go.mod, requirements.txt, Gemfile, *.csproj, build.gradle, etc.).
2. Tell the user what you found and which SDK you recommend.
3. Wait for confirmation before fetching 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.

SDK Skills

| Platform | Skill | Path | |---|---|---| | Android | sentry-android-sdk | sentry-android-sdk/SKILL.md | | browser JavaScript | sentry-browser-sdk | sentry-browser-sdk/SKILL.md | | Cloudflare Workers and Pages | sentry-cloudflare-sdk | sentry-cloudflare-sdk/SKILL.md | | Apple platforms (iOS, macOS, tvOS, watchOS, visionOS) | sentry-cocoa-sdk | sentry-cocoa-sdk/SKILL.md | | .NET | sentry-dotnet-sdk | sentry-dotnet-sdk/SKILL.md | | Elixir | sentry-elixir-sdk | sentry-elixir-sdk/SKILL.md | | Go | sentry-go-sdk | sentry-go-sdk/SKILL.md | | NestJS | sentry-nestjs-sdk | sentry-nestjs-sdk/SKILL.md | | Next.js | sentry-nextjs-sdk | sentry-nextjs-sdk/SKILL.md | | Node.js, Bun, and Deno | sentry-node-sdk | sentry-node-sdk/SKILL.md | | PHP | sentry-php-sdk | sentry-php-sdk/SKILL.md | | Python | sentry-python-sdk | sentry-python-sdk/SKILL.md | | Flutter and Dart | sentry-flutter-sdk | sentry-flutter-sdk/SKILL.md | | React Native and Expo | sentry-react-native-sdk | sentry-react-native-sdk/SKILL.md | | React | sentry-react-sdk | sentry-react-sdk/SKILL.md | | Ruby | sentry-ruby-sdk | sentry-ruby-sdk/SKILL.md | | Svelte and SvelteKit | sentry-svelte-sdk | sentry-svelte-sdk/SKILL.md |

Platform Detection Priority

When multiple SDKs could match, prefer the more specific one:

• Android (build.gradle with android plugin) → sentry-android-sdk
• Cloudflare (wrangler.toml or wrangler.jsonc) → sentry-cloudflare-sdk over sentry-node-sdk
• NestJS (@nestjs/core) → sentry-nestjs-sdk over sentry-node-sdk
• Next.js → sentry-nextjs-sdk over sentry-react-sdk or sentry-node-sdk
• Flutter (pubspec.yaml with flutter: dependency or sentry_flutter) → sentry-flutter-sdk
• React Native → sentry-react-native-sdk over sentry-react-sdk
• PHP with Laravel or Symfony → sentry-php-sdk
• Elixir (mix.exs detected) → 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

Quick Lookup

Match your project to a skill by keywords. Append the path to https://skills.sentry.dev/ to fetch.

Finding the DSN

If the user doesn't have their DSN, guide them to find it:

1. Open the Sentry project settings page: https://sentry.io/settings/projects/
2. Select the project
3. Click "Client Keys (DSN)" in the left sidebar
4. 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.
