Agentic Infrastructure

Infrastructure built for AI-native delivery

Agentic development only works when the infrastructure around it can keep up. The right delivery stack turns more agent output into faster engineering cycles and smoother releases.

When delivery becomes the bottleneck

Turn AI output into
faster product delivery.

Agents increase implementation speed, but the bottleneck does not stay there for long. It moves into the delivery systems that now have to keep pace with more code and more change.

Review AI-written code faster.

A QA agent checks output on real devices and in delivery workflows, so faster implementation does not turn into slower releases.

Own your delivery infrastructure.

Self-hosted CI, device, and release infrastructure stay inside your environment, with agents handling the maintenance work around them.

Open source at the core.

The stack builds on tooling your team can audit, extend,
and keep using as needs evolve.

Make delivery faster, and releases smoother.

AI-Driven QA + Testing

Keep QA ahead of agentic delivery

AI-native teams need verification that keeps up with local and cloud agents. We provide an AI QA agent that checks work in real time on devices, locally and on pull requests, so regression checks, exploratory QA, and release validation become part of the delivery flow.

Use Cases

AI-Native Test Automation

Run automated checks against code written by engineers and agents, so QA keeps pace with faster implementation.

Automated Accessibility Audits for EEA

Check interfaces for accessibility issues during delivery, helping teams catch compliance gaps before release.

Cross-Platform Code Verification

Validate behavior across platforms from one QA flow, so shared code does not hide platform-specific issues.

AI-Generated Code Validation

Review AI-written UI and logic before merge, so speed does not introduce regressions, edge-case failures, or bad implementation choices.

Release Validation

Run final checks on critical journeys, builds, and environments before rollout starts.

Regression Prevention

Catch regressions in core flows with validation wired into pull requests, CI, and pre-release checks.

On-Prem & Cloud QA Execution

Run the same QA agent inside your own infrastructure or in hosted environments, depending on policy and scale.

Put an AI QA agent in your flow

Tell us where testing slows your team down today. We'll come back with a plan to wire the QA agent into your delivery flow and what to prove out first.

Custom Agents

Put agents on recurring engineering work.

Teams get more from AI when agents take on repeatable engineering work. We set up internal agents and workflows so work can run in parallel and continue after a developer session ends.

Use Cases

Code Review Agents

Check PRs for regressions, missing tests, weak patterns, and team standards before human review.

Upgrade Agents

Run framework, dependency, and React Native upgrade work with repeatable checks and migration steps.

Maintenance Agents

Handle routine cleanup, dependency updates, deprecated APIs, and repo hygiene before they block delivery.

Documentation Agents

Keep technical docs, changelogs, release notes, and implementation notes aligned with code changes.

CI/CD Automation Agents

Automate build checks, pipeline fixes, test reruns, release gates, and rollout steps across your delivery workflow.

Internal Tool Agents

Connect agents to tickets, repos, CI, Slack, Linear/Jira, and internal systems with scoped access and clear rules.

Build agents for your delivery workflow

Show us your most repetitive workflows. We will build custom agents that handle the heavy lifting while your team focuses on high-impact work.

Turn team habits into tools
Grow output without hiring linearly

Self-Hosted CI/CD Infrastructure

Run delivery infrastructure on your terms.

Hosted delivery infrastructure does not fit every cost, security, or control requirement. Our self-hosted CI/CD, OTA, and agent execution infrastructure lets teams run delivery on their own terms and keep more of the stack under their control.

Use Cases

Release Automation

Automate build, signing, testing, and rollout steps so releases need less manual coordination.

CI/CD Modernization

Replace brittle pipelines with faster, more observable workflows built for current delivery demands.

Build & Test Acceleration

Shorten feedback loops with better caching, parallelization, and runners tuned to your workloads.

OTA Rollout Management

Ship changes and bug fixes between App Store releases through over-the-air updates.

Release Monitoring & Alerting

Monitor releases and trigger alerts when rollout, build, or post-release signals show risk.

Deployment Health Visibility

Give teams a live view of pipeline status, release progress, and post-release health across environments.

Delivery Cost Optimization

Reduce spend on hosted runners, device clouds, and release tooling by moving the right parts of the stack in-house.

Move delivery infrastructure in-house

Send us your current CI/CD, Observability and release stack. We'll come back with a migration plan to build tooling on your own infrastructure.

Agent React DevTools: Give AI Agents Access to React Internals

Agent React DevTools gives AI agents direct access to the React component tree, state, and performance data. Instead of relying only on UI snapshots, agents can now inspect what happens inside React and debug issues with proper context. This enables more reliable QA, better performance analysis, and deeper automation for React and React Native apps.
