Samva

Open-source packages, examples, cookbooks, and agent plugins for integrating Samva into real applications.

Use these to send transactional email, connect auth email flows, work with templates, handle delivery events, and verify signed webhooks. Ask questions about the code on DeepWiki.

Structure

• packages/* — package integrations (@samva/*).
• examples/* — complete, runnable example apps.
• cookbooks/*.md — documentation-first, copy-pasteable recipes.
• plugins/* — coding-agent plugins and public documentation.

The maintained integrations target the published Samva 0.11 SDK. Workspace packages and examples use samva@^0.11.0; copyable external import maps pin samva@0.11.0.

Package integrations

• @samva/better-auth — Better Auth email callbacks powered by Samva.
• @samva/email-sdk — Provider-owned Samva community adapter for Email SDK.

Agent plugins

• samva — OpenAI Codex and Cursor packaging for the canonical hosted MCP server and Samva agent skill.
