Depot is growing from a build accelerator into a full CI and agent-sandbox platform.
Depot's recent releases cluster around its CI product reaching general availability (API and CLI GA, native step retries, durable cache disks, test-result ingestion) plus a Sandbox SDK for running agent-generated code. The company is clearly broadening past its original remote-build-cache niche. The cadence is high and feature-dense.
Resend ships a tight, frequent changelog: richer email content and deeper dev-tool reach
Resend is executing the developer-first email playbook with a clean, high-cadence changelog of real features. Recent releases split cleanly between richer email/editor capabilities (Open Graph previews, embedded charts) and embedding Resend into the tools developers already use (Vercel, Claude Code, Auth0, MCP).

The company is clearly broadening past its original remote-build-cache niche. The cadence is high and feature-dense.
Two arcs are visible: hardening CI into a complete, programmable system (retries, caching, test reporting, an OpenAPI-described API), and staking out the agent-execution space with an ephemeral Sandbox SDK. Both target teams that want builds, CI, and untrusted-code execution from one vendor. Expect the Sandbox SDK to move toward GA and CI to keep filling parity gaps with incumbents.
Next likely: the Sandbox SDK exits private beta, and CI adds more of the surface teams expect (broader test-framework ingestion, richer run analytics) now that its API and CLI are GA.

Recent releases split cleanly between richer email/editor capabilities (Open Graph previews, embedded charts) and embedding Resend into the tools developers already use (Vercel, Claude Code, Auth0, MCP).
Two arcs are compounding: AI-native composition (mentions in AI chats, AI column mapping on CSV import, chart components) and distribution through integrations (Vercel Marketplace, an official Claude Code plugin, an MCP server, Auth0). Resend is trying to be the email layer that shows up wherever devs and agents already are, not a destination they visit.
Expect more agent- and MCP-facing surface plus marketplace integrations, alongside continued audience tooling building on the CSV import. The cadence is steady incremental execution rather than big directional bets.
