What is Sentry?

Sentry pushes Seer into open beta and ramps AI-agent observability.

Sentry is now running on two visible tracks: an AI track around Seer (root-cause analysis, Claude-driven fixes, and now an open-beta conversational agent) and a steady SDK expansion track (Nitro, Cloudflare Workers RPC trace propagation, LangGraph instrumentation, multi-module Android source context). The Alerts product is being split into Monitors and Alerts, the first structural change to that surface in a while.

What is Resend?

Resend keeps widening from a raw email API into agent-native tooling and audience management.

Resend remains a developer-first email platform, but its recent surface area is splitting in two directions. One track is agent-native access — an MCP server, a CLI built for humans and AI agents, a Claude Code plugin, and AI-assisted authoring. The other is audience and content tooling — bulk CSV contact import, in-email charts, and richer broadcast composition — pushing it past pure transactional sending.

Sentry pushes Seer into open beta and ramps AI-agent observability.

◆ Current state

Sentry is now running on two visible tracks: an AI track around Seer (root-cause analysis, Claude-driven fixes, and now an open-beta conversational agent) and a steady SDK expansion track (Nitro, Cloudflare Workers RPC trace propagation, LangGraph instrumentation, multi-module Android source context). The Alerts product is being split into Monitors and Alerts, the first structural change to that surface in a while.

◆ Where it's heading

Sentry is moving from an error-tracker that AI uses to debug, toward an AI-native debugging surface — Seer is being upgraded from a feature into the primary user, and the addition of LangGraph instrumentation signals Sentry wants to be the observability layer for agentic apps too. The Perforce GA shows the enterprise courtship continues alongside the AI bet.

◆ Prediction

Expect Seer Agent to leave open beta with broader chat surfaces (IDE, web, CLI), more model partners beyond Claude, and additional agent-framework instrumentation (CrewAI, AutoGen, OpenAI Agents SDK). The Monitors/Alerts split likely seeds an SLO product as the next directional move.

Resend keeps widening from a raw email API into agent-native tooling and audience management.

◆ Current state

Resend remains a developer-first email platform, but its recent surface area is splitting in two directions. One track is agent-native access — an MCP server, a CLI built for humans and AI agents, a Claude Code plugin, and AI-assisted authoring. The other is audience and content tooling — bulk CSV contact import, in-email charts, and richer broadcast composition — pushing it past pure transactional sending.

◆ Where it's heading

The pattern across these releases is Resend trying to own both ends of the email stack: the programmatic API developers integrate, and the audience layer that marketing tools like Mailchimp and Loops occupy. The agent-native investments suggest it expects a growing share of email to be triggered and composed by AI tools rather than hand-written code. Contact import at scale is the clearest sign it wants the audience database, not just the send.

◆ Prediction

Expect the audience side to deepen next — segmentation, list management, or analytics on top of the imported contacts — to match the broadcast and authoring features already shipped.
