Amplitude vs Calibre: at a glance
What is Amplitude?
Amplitude shipped AI Visibility 2.0 with MCP, agentic onboarding, and a new Premium plan tier.
April's release wave is dominated by an AI Visibility 2.0 expansion (sentiment, recommendations, event data, MCP support, and a new Premium plan tier) and a Wizard CLI for agentic onboarding. Around it, Amplitude added Session Replay capabilities (page-level URL masking, replay insights, bookmarkable replays, sentiment filter), a Global Agent chat sidebar that opens by default, and AI-feedback plumbing (ingestion API, AI Assistant chats fed into feedback). The captured feed includes three near-duplicate March-31 capture variants of the same April digest, plus older monthly digests back to August.
What is Calibre?
Calibre MCP lets your coding agent read RUM and Lighthouse data, then fix the slow code
Calibre now ships a read-only MCP server that gives Claude Code, Cursor, Codex, Copilot, Claude and ChatGPT access to an account's RUM, CrUX and Synthetic data, included on every plan. It came days after Test Agents moved to Chrome 156 and Lighthouse 13.6.0. The latest entry is a design tidy-up that places each page's Guide link in the same top-right spot.

Amplitude shipped AI Visibility 2.0 with MCP, agentic onboarding, and a new Premium plan tier.
◆ Current state
April's release wave is dominated by an AI Visibility 2.0 expansion (sentiment, recommendations, event data, MCP support, and a new Premium plan tier) and a Wizard CLI for agentic onboarding. Around it, Amplitude added Session Replay capabilities (page-level URL masking, replay insights, bookmarkable replays, sentiment filter), a Global Agent chat sidebar that opens by default, and AI-feedback plumbing (ingestion API, AI Assistant chats fed into feedback). The captured feed includes three near-duplicate March-31 capture variants of the same April digest, plus older monthly digests back to August.
◆ Where it's heading
The compounding theme across six months: Amplitude is becoming an agentic analytics platform — Chart Chat in September, Amplitude MCP launched in October, Dashboard Agent in February, External MCP Tools in January, Global Agent and now AI Visibility 2.0 with MCP in April. The Premium plan tier introduced with AI Visibility 2.0 is the monetization step that signals AI is being treated as a separate revenue line, not a free upgrade. Session Replay is on a parallel track maturing into a serious enterprise feature.
◆ Prediction
Watch for the Wizard CLI to evolve into a fuller programmable agentic onboarding flow — likely tied into Amplitude's CDP and customer-data layer. The Premium plan tier will likely accumulate AI-only features (advanced sentiment, agent compute), turning the AI suite into a clean upsell from the analytics base.

Calibre MCP lets your coding agent read RUM and Lighthouse data, then fix the slow code
◆ Current state
Calibre now ships a read-only MCP server that gives Claude Code, Cursor, Codex, Copilot, Claude and ChatGPT access to an account's RUM, CrUX and Synthetic data, included on every plan. It came days after Test Agents moved to Chrome 156 and Lighthouse 13.6.0. The latest entry is a design tidy-up that places each page's Guide link in the same top-right spot.
◆ Where it's heading
Calibre is turning its monitoring data into something agents act on rather than something people read in dashboards. The summer work on deployment markers, all-pages aggregates and the audit log built the context and governance an agent needs: which deploy, which page, who connected. Expect the remaining surface to follow the same path, with agents both querying performance and being measured by it.
◆ Prediction
The likely next step is write access or deploy-linked workflows over MCP, such as an agent opening a fix tied to a regression marker, since the current server is explicitly read-only and the launch frames fixing as the goal.
