What is Appwrite?
Appwrite is spending this quarter on latency: the CLI, cold starts, and now builds.
Appwrite Cloud is being tuned end to end for speed. The CLI was rewritten from Node to a single Go binary, function cold starts now mount a compressed SquashFS artifact instead of extracting files, and builds cache the package manager's store between runs. Alongside that, the MCP thread went both ways in a fortnight: Appwrite's own MCP server moved to a hosted remote endpoint, and a Functions template turned the platform into somewhere to host your own. Cloud economics are tightening in the background, with build and deployment storage billed from September 1 and scheduled executions jittered on Free and Education plans.
What is httpuv?
httpuv ships almost nothing, which is what you want from the web server under Shiny
httpuv is the C++ HTTP and WebSocket server that Shiny runs on. Across this window it added exactly one user-facing function - runStaticServer() for serving a directory - and spent every other release on race conditions, compiler and linker changes, CRAN check warnings, and mime type table updates.

Appwrite is spending this quarter on latency: the CLI, cold starts, and now builds.
◆ Current state
Appwrite Cloud is being tuned end to end for speed. The CLI was rewritten from Node to a single Go binary, function cold starts now mount a compressed SquashFS artifact instead of extracting files, and builds cache the package manager's store between runs. Alongside that, the MCP thread went both ways in a fortnight: Appwrite's own MCP server moved to a hosted remote endpoint, and a Functions template turned the platform into somewhere to host your own. Cloud economics are tightening in the background, with build and deployment storage billed from September 1 and scheduled executions jittered on Free and Education plans.
◆ Where it's heading
Every performance entry in this window targets the same path: the loop between a code change and a running deployment. Install time, extraction time, process start time — each is being removed in turn, with real before-and-after numbers rather than claims. That path matters most when something invokes it repeatedly, which is where the CLI rewrite and the MCP work point: CI pipelines and coding agents driving a project through its own tooling. The pricing changes run on a parallel track, drawing the line between what is free and what is guaranteed.
◆ Prediction
The cold-start work is currently limited to new deployments and favours larger artifacts, so extending it — or automating the redeploy it requires — is the obvious follow-up. The September 1 storage enforcement is dated and will land; expect deployment retention controls to get more attention as it approaches.
httpuv
0.0DEVOPS
httpuv ships almost nothing, which is what you want from the web server under Shiny
◆ Current state
httpuv is the C++ HTTP and WebSocket server that Shiny runs on. Across this window it added exactly one user-facing function - runStaticServer() for serving a directory - and spent every other release on race conditions, compiler and linker changes, CRAN check warnings, and mime type table updates.
◆ Where it's heading
There is no direction here in the usual sense, and that is the honest read: the package is a stable foundation whose releases are triggered by the toolchain moving, by R-devel warnings, or by a threading bug surfacing under load. The one recurring theme with substance is connection reliability - WebSocket keepalive pings, race conditions in the I/O thread - which is what actually breaks Shiny apps in production.
◆ Prediction
Expect continued small releases tracking Rtools, R-devel and mime data, with any substantive change most likely coming from a threading or WebSocket issue reported by Shiny users rather than from planned work.
