What is FullStory?

FullStory's release feed is empty — no usable signal in the changelog stream.

The only captured entry is navigation chrome ('Follow us') with no release content. This means our scraper isn't finding FullStory's actual changelog or that releases aren't being published in a machine-readable form on the public surface we monitor.

What is Resend?

Resend embeds into Stripe Projects as a provisionable dependency, accelerating platform distribution

Resend is a developer-first email API that has been systematically expanding from transactional email into a full email platform — adding Broadcasts, Segments, template components, and analytics on top of its send API. The September batch shows both directions simultaneously: new API surface for power users (headless webhooks, click link analytics, duplicate broadcast) and enterprise controls (SSO). Notably, the Headless Webhook API explicitly lists the MCP server as a delivery vehicle alongside SDKs and CLI.

FullStory's release feed is empty — no usable signal in the changelog stream.

◆ Current state

The only captured entry is navigation chrome ('Follow us') with no release content. This means our scraper isn't finding FullStory's actual changelog or that releases aren't being published in a machine-readable form on the public surface we monitor.

◆ Where it's heading

Trajectory cannot be assessed from the available data. The scraper either needs a different source URL or FullStory has shifted release communication elsewhere (in-product, customer portal, or blog-only).

◆ Prediction

Until a new source is wired in, no prediction is possible. Worth flagging this product for source-discovery work rather than commentary.

Resend embeds into Stripe Projects as a provisionable dependency, accelerating platform distribution

◆ Current state

Resend is a developer-first email API that has been systematically expanding from transactional email into a full email platform — adding Broadcasts, Segments, template components, and analytics on top of its send API. The September batch shows both directions simultaneously: new API surface for power users (headless webhooks, click link analytics, duplicate broadcast) and enterprise controls (SSO). Notably, the Headless Webhook API explicitly lists the MCP server as a delivery vehicle alongside SDKs and CLI.

◆ Where it's heading

The distribution strategy is sharpening: Stripe Projects provisioning and the earlier Vercel v0 integration put Resend inside platforms where developers are already making infrastructure choices. This embed-into-the-platform approach is a deliberate acquisition channel that bypasses the usual signup funnel. Combined with SSO (unlocking enterprise team adoption) and continued API surface expansion, Resend is moving toward capturing both the individual developer and the team buying motion.

◆ Prediction

More platform integrations following the Stripe and Vercel pattern are the most likely next moves. On the analytics side, click tracking just shipped — open rate and conversion attribution are the logical extensions that would round out the Broadcasts feature set.
