What is Expo?
Expo shut down its own agent and is wiring itself into the ones developers already use.
Expo wound down the Expo Agent closed beta in July, two months after making its MCP server free on every plan, and has now shipped a way to connect Expo from the Claude desktop app. Everything else in the window is core platform work: SDK 56 and 57, EAS Observe scheduled for general availability on August 20, a Maestro test insights dashboard, and automated iOS device registration in EAS Workflows.
What is q2?
Ten releases in six days, methodically porting Quarto's surface into a Rust binary.
q2 is the Quarto team's Rust reimplementation of Quarto, shipping as a statically linked single binary with signed release archives and a bundled Quarto Hub MCP server. It is explicitly marked experimental and not production-ready, and it is moving fast — ten releases between 7 and 13 August. The release notes are raw commit logs rather than curated summaries, and reading them shows a consistent programme: work items are investigated, design decisions recorded, tests written red, then implemented in numbered phases, with 'Q1 parity' as the recurring benchmark against the existing Quarto.

Expo

Expo shut down its own agent and is wiring itself into the ones developers already use.
◆ Current state
Expo wound down the Expo Agent closed beta in July, two months after making its MCP server free on every plan, and has now shipped a way to connect Expo from the Claude desktop app. Everything else in the window is core platform work: SDK 56 and 57, EAS Observe scheduled for general availability on August 20, a Maestro test insights dashboard, and automated iOS device registration in EAS Workflows.
◆ Where it's heading
The pattern is conceding the assistant layer and defending the build, test, and deploy pipeline underneath it. Instead of competing for the agent surface, Expo is making project data reachable from whichever assistant a developer already runs — the free MCP server first, now a Claude desktop connection. EAS meanwhile keeps absorbing more of the release pipeline: observability heading to GA, end-to-end test insights, device provisioning automated.
◆ Prediction
More connector and MCP surface for other assistant hosts is the likely next step, alongside EAS work around what is already in flight — particularly Observe once it reaches GA on August 20. The entries give no indication of whether the SDK release cadence changes as a result.
q2
6.3INFRA · APIS
Ten releases in six days, methodically porting Quarto's surface into a Rust binary.
◆ Current state
q2 is the Quarto team's Rust reimplementation of Quarto, shipping as a statically linked single binary with signed release archives and a bundled Quarto Hub MCP server. It is explicitly marked experimental and not production-ready, and it is moving fast — ten releases between 7 and 13 August. The release notes are raw commit logs rather than curated summaries, and reading them shows a consistent programme: work items are investigated, design decisions recorded, tests written red, then implemented in numbered phases, with 'Q1 parity' as the recurring benchmark against the existing Quarto.
◆ Where it's heading
The project is working through the original Quarto's feature surface item by item — project profiles, environment files, shortcodes in metadata, listings, callouts, crossrefs, TOC handling, aliases — while building infrastructure the original lacks, notably a numbered diagnostic catalogue (Q-2-47, Q-14-4 and so on) with a lint that requires a documentation page for every error code. Version 0.18.0's Lua filter support is the load-bearing one, since Quarto's extension ecosystem is written in Lua. Distribution choices point at the same goal: musl-static Linux builds, minisign signatures, no glibc requirement.
◆ Prediction
Expect the parity grind to continue at this cadence, with the remaining high-value Q1 features and diagnostic coverage as the visible queue. The commit logs also show npx distribution planned for the MCP server, which is the nearest thing to a stated roadmap item in these entries.
