Its Unified Code Base (UCB) is the Linux-based distribution and application framework for in-vehicle systems; SoDeV is a newer reference platform built around UCB to support software-defined vehicle development with technologies including containers, virtualization and Zephyr RTOS.
What AGL is—and what it is not
AGL is a collaborative software project, not a finished operating system that an individual can install into any production car. Automakers and suppliers contribute to a shared software base with the aim of reducing duplicated development work across vehicle programs.
AGL describes its approach as “code first”: provide a shared starting point and standardized APIs so developers can port an application once for AGL UCB users. That is the project’s intended benefit, not an independently quantified finding that every participating program saves a particular amount of time or money.
What the Unified Code Base includes
UCB is a Linux distribution jointly developed for in-vehicle infotainment and connected-car systems. AGL’s software documentation describes an application framework and capabilities that can be assembled for different vehicle projects; it does not mean every deployment uses every feature.
#1 Best Overall
- Application and user-interface support: an application framework, multiple displays, and speech-recognition APIs.
- Connectivity: ConnMan network management and IP networking, including Wi-Fi and LTE.
- Vehicle and audio functions: vehicle-bus messaging, audio routing and mixing.
- Platform and security: Yocto Project-based builds and Linux Security Module facilities.
- Vehicle profiles: documented profiles for telematics and instrument clusters.
AGL’s stated goal is to develop “70–80% of the starting point for a production project.” This is a project target, not a measured guarantee that UCB is production-ready for a given car or that only 20–30% of engineering work remains. Each program still has to integrate and validate its hardware, software, interfaces and vehicle-specific requirements.
How the AGL software is organized
AGL architecture documentation describes a layered system: applications and HMI at the top, an application framework beneath them, services below that, and operating-system components—including the kernel, drivers and standard utilities—at the base. This separation gives developers places to work at different levels, but the particular components and integrations depend on the target and project.
AGL’s expert groups cover areas such as application frameworks and security, navigation, speech, UI and graphics, connectivity, continuous integration and testing, clusters, IVI, vehicle-to-cloud services and virtualization. This breadth reflects a collaborative project spanning multiple technical domains, not a promise that every area is equally mature or included in every UCB build.

What SoDeV adds for software-defined vehicle development
SoDeV—AGL’s software-defined vehicle reference platform—is built around UCB and brings together additional open-source technologies. AGL announced its initial availability to developers on May 14, 2026, through the UCB release it called “Ultimate Unagi.” The announced stack combines UCB with Linux containers, VirtIO, the Xen hypervisor, Zephyr RTOS and other Linux Foundation projects.

In its May 2026 announcement, AGL described initial operation on Renesas Sparrow Hawk reference boards, cloud-based processor environments and virtual machines, with broader automotive SoC support planned during 2026. These are release-era statements about the platform’s direction and initial environments; they do not establish that every SoDeV component runs on every automotive processor.
Release names and support context
AGL release names can be confusing because public pages may describe different release contexts. The AGL UCB page surfaced UCB 16.0, “Prickly Pike,” while the May 2026 SoDeV announcement referred to “Ultimate Unagi” as the latest release at the time of that announcement. Check the branch and release notes for the specific build you intend to use rather than treating those labels as interchangeable.
AGL’s May 2026 announcement said Ultimate Unagi updated to Yocto Project Scarthgap LTS 5.0.16 and included updates to Flutter tooling, Vehicle Signal Specification coverage and the Distributed Display Framework. It also described a two-year support period and updates approximately three weeks after Yocto Project Scarthgap releases. Those are plans attributed to AGL in that announcement; confirm current branch maintenance and update status before relying on them.
Which hardware can you use to evaluate AGL?
Hardware support varies by branch, integration and board configuration. The current AGL master instrument-cluster/container integration guide lists the following tested configurations. “Tested” here refers to that documented integration, not automotive production qualification or safety certification.
| Board | Configurations listed as tested | Guide recommendation |
|---|---|---|
| NanoPC-T6 | 4 GB, 8 GB and 16 GB | Recommended |
| Raspberry Pi 4 or Raspberry Pi 5 | 4 GB and 8 GB | Raspberry Pi 5 recommended |
| Renesas R-Car V4H Sparrow Hawk | Configuration not stated in the guide summary | Recommended |
For a reader following that particular integration, a Raspberry Pi 5 with 4 GB or 8 GB is an evaluation option; it is not a universal UCB compatibility claim. The guide also warns that some integrated builds require substantial host storage, so consult its target-specific build instructions before setting up a development machine.

A development board that boots a demonstration is not thereby an automotive-qualified ECU. Production use requires the vehicle program’s own hardware integration, validation and applicable safety and security work.

- Choose the use case and target first. Decide whether you are exploring IVI, an instrument cluster or the SoDeV integration, then match that to a documented board and memory configuration.
- Select a branch deliberately. AGL documentation distinguishes stable release branches, which are static tested snapshots, from the dynamic master branch, where newer features are under development. The available build and hardware instructions differ by branch and target.
- Check out the source using AGL’s documented workflow. The Unagi developer documentation directs developers to the AGL Gerrit server for source files and Yocto layers managed with the
repotool. Follow the checkout and manifest instructions for your selected branch rather than assuming a command or manifest applies to all targets. - Follow the board-specific build guide. Confirm prerequisites, host storage needs, board setup and integration steps in the relevant AGL documentation. A build for one board or branch should not be assumed to transfer unchanged to another.
- Treat the result as an evaluation build. A working image is useful for development and learning; it does not establish production suitability, automotive qualification or certification.
Project participation and what adoption claims show
AGL’s Join page reported “more than 150 members, including 10 automakers,” as accessed October 7, 2026. That is AGL’s own membership figure, not an independently audited count of active deployments or market share. In May 2026, AGL announced five new members: EMQ, Lineo Solutions, MediaTek, VA Linux Systems Japan and Very Good Ventures.
AGL’s homepage also publishes statements from member-company executives describing why their organizations use or support the platform. Those statements are useful evidence of the companies’ stated rationale; they are not independent proof of industry-wide cost savings, faster development, or production outcomes. The source material cited here does not establish comparative figures for those outcomes across the AGL ecosystem.

Where to look for commercial offerings
AGL’s Vendor Marketplace lists products and services from members. Its stated requirements say vendors must be current AGL members and their offers must support or use UCB and be launched and currently available. Marketplace inclusion alone does not establish that a vendor offers an affiliate or referral program.
