OUR PRODUCTS / PROJECT NOTES
A closer look at the build.
Three independent products at different stages of development. Here is what each one is for, what is built and what is still evolving.
01Penta
Collaborative workspaceIn development
For teams mapping and tracking a shared process.
Process diagrams and task lists often live apart. Penta brings the steps, checklists and supporting notes onto one shared canvas.
Discuss Penta- Built so far
- Connected nodes, checklists and progress; live collaboration with access roles; snapshots, version history, restore and JSON export.
- Current stage
- Experimental personal project. Core workflows are implemented; AI expansion is not implemented yet.
- React / TypeScript
- React Flow
- Yjs / PartyKit
- Cloudflare
02Proxxy
Security testingIn development
For developers and security testers investigating web traffic.
Testing across different environments makes requests harder to follow. Proxxy brings distributed traffic capture and inspection into one operator workspace.
Discuss Proxxy- Built so far
- HTTP/HTTPS inspection, agent management and project scope; Repeater and Intruder tools; browser flow recording, replay and visual workflows.
- Current stage
- In development. The intercept interface and larger history and workflow flows are still being refined.
- Rust
- SvelteKit
- GraphQL / gRPC
- SQLite
03Opmerk
AI visibility, SEO & website feedbackLive product
For businesses and the people who look after their website: owners, marketing teams, designers, developers and the agencies that work for them.
Customers also put their questions to AI services, while website feedback, SEO findings and fixes often sit in separate tools. Opmerk asks ChatGPT, Claude, Gemini and other AI services the questions a business tracks, shows whether it is named, recommended and cited, and keeps page checks and team feedback on the live website in the same workspace.
Explore Opmerk- Built so far
- Web app with a Chrome extension; no code is added to the website. Core covers the review workflow: feedback pinned to page elements with screenshots, threads, tasks, owners and review states, realtime presence and live cursors, notifications, and browser SEO and information-disclosure checks. Pro adds cloud site scans with automatic discovery, Site readiness checks and full SEO reports, AI Visibility across ChatGPT, Perplexity, Claude, Gemini, DeepSeek and Grok with competitor tracking, competitor ads and search rankings, AI Insights, Attention Review with snapshots and client reports, and MCP access for Claude Code, Codex, Cursor and VS Code within project permissions. Attention Review predicts likely visual attention; it does not track visitors.
- Current stage
- Live product with Core and Pro project modes; accounts are created by invitation and public pricing has not been announced. AI Visibility is enabled per Pro project, with a monthly quota for AI calls and competitor captures.
- Chrome extension
- React / TypeScript
- Cloudflare Workers
- Durable Objects
- MCP
- AI APIs & OpenRouter
- Integrations: Claude Code / Codex / Cursor / VS Code

HOW WE CAN HELP
Software to build. Security to trust.
Build a new application, improve an existing product or assess its security. Cloud integrations and AI support the work where they add value.
01CUSTOM SOFTWARE
Software that fits your work.
Web applications, browser extensions and internal tools. From interface and data model to a tested release, with source code and documentation for the next iteration.
Explore custom software02APPLICATION SECURITY
Security, tested in practice.
Web and API penetration testing, cloud and Kubernetes hardening, and security checks in CI/CD. Findings become prioritised fixes, with technical evidence and remediation guidance.

Ideas in motion.
Products in progress.
Our products explore three different problems: mapping a process, inspecting traffic and reviewing a website. This motion study brings those connections into view.
HOW WE WORK
From brief
to handover.
Clear scope, regular reviews and a practical handover. You stay involved throughout the build.
Discuss your projectDiscover
Define the brief.
Agree on the users, the problem and the scope. Define what needs to work and how we will review it.
Workflow mapScope & boundaries
Develop
Build and review.
Work in small, reviewable iterations. Test the interface, integrations and security as the application takes shape.
