OpenClaw, an open-source self-hosted AI assistant, released version
2026.4.25 to improve system performance. The update introduces a cold persisted registry for plugins, which eliminates broad manifest scans to reduce boot times. It also expands OpenTelemetry (a framework for tracking system health) to cover model calls and tool loops.This release shifts the platform toward Agentic Engineering (the discipline of building reliable agent systems). By exposing granular telemetry and extending browser automation improvements, OpenClaw addresses the "black box" problem of autonomous agents. This follows the recent hardening of agent security and improvements to persistent background orchestration to make self-hosted agents viable for 24/7 production use.
You can now assign distinct vocal identities to agents using new TTS personas and providers like ElevenLabs v3. The update is available as a free open-source download. For those on limited hardware like a Raspberry Pi, the new browser doctor helps stabilize web-based automation tasks.
Still wondering? A few quick answers below.
OpenClaw is an open-source, self-hosted AI assistant designed to run on your own hardware while connecting to messaging platforms like WhatsApp, Telegram, and Discord. It functions as an autonomous agent that can manage emails, calendars, and home automation. The platform emphasizes user control and privacy by keeping your data on your own machine.
The v2026.4.25 release significantly expands text-to-speech capabilities by adding support for several new providers. These include Azure Speech, ElevenLabs v3, Xiaomi MiMo, Inworld, and Volcengine. Users can also use a local CLI speech provider, which allows for voice synthesis using local command-line tools instead of relying solely on cloud-based API services.
Previously, OpenClaw scanned every plugin folder and manifest file during the boot process, which could cause delays. The new cold persisted registry stores plugin metadata in a dedicated index, allowing the system to identify and load plugins without performing broad directory scans. This change makes the startup process more deterministic and significantly faster for complex installations.
