Questions & Answers
- Mobile first by design. Measure is built by mobile engineers for mobile teams, not adapted from a web or backend APM tool.
- Full session context. Session replays and timelines show the user actions, navigations, network calls and logs that led to an issue, not just a stack trace.
- Coverage beyond crashes. Crashes, ANRs, performance traces, network performance, bug reports, user journeys and app health metrics live in a single dashboard.
- Open source and self hostable. Apache 2.0 licensed, so teams can keep all app and user data inside their own infrastructure.
- Cost control. Per GB pricing combined with Adaptive Capture, which lets teams increase data collection during a risky release and reduce it afterwards without shipping an app update.
- Broad platform support. Android, iOS, Flutter, React Native and Kotlin Multiplatform.
- Agent ready. An MCP server exposes errors, traces and session data to coding agents and Slack for natural language debugging.
- Editor: TypeScript, Vue, Vite
- Backend: Node.js, Fastify, PostgreSQL
- Desktop: Tauri
In 1996 the anthropologist Julian Orr showed that Xerox's official documentation had drifted away from what people actually saw in the field. The real knowledge was tacit: in people's heads and in their war stories. Thirty years later FMEAs have the same problem, from design through process to the plant floor. They are written once for the audit and slowly go out of date. Design never hears what the field learned, and the engineers who know better retire. Tacit AI is named after that knowledge. We built it to turn what is scattered across specs, process documents, manuals, failure reports and engineers' experience into design, process and equipment risk analyses that stay connected to the evidence.
Solitaire Arcade began as an independent project to build simple, accessible versions of classic card games for the web. It launched in August 2026 as the first live project under the broader Chalky Arcade game-development project and continues to grow with new games, guides and player features.

URL Verifier Pro was created after years of using existing URL checking tools that had become expensive subscription services or included many features that weren't needed. The goal was to build a fast, native Windows application focused on bulk URL verification, giving professionals a reliable tool that performs the essential technical checks without unnecessary complexity or ongoing monthly costs.
People choose PlexTrac because it:
Saves time — teams report saving 30–70% of the time previously spent on manual reporting and remediation tracking.
Centralizes security data — findings from scanners, pentests, bug bounty platforms, and red team ops are all in one place.
Prioritizes what matters — contextual risk scoring helps teams focus on the vulnerabilities that actually pose a business risk.
Enables automation — from report generation to ticketing workflows with Jira, ServiceNow, and more.
Works for both enterprises and MSSPs — with multi-tenant support, customizable templates, and powerful integrations.
Bottom line: PlexTrac turns vulnerability noise into actionable, trackable, and reportable outcomes.

FREEDOM was created from the real-world experience of running a service business and dealing with the challenge of keeping projects, customers, schedules, equipment, follow-ups, and day-to-day responsibilities organized. It was built to create one reliable operational system where an owner can see what is happening, what needs attention, and what comes next.
Axiospec was built by CaliTech LLC after watching quality teams run calibration programs out of spreadsheets, paper binders, and desktop tools that only ran on one machine in the corner of the lab.
The pattern was always the same. The records existed, but they were scattered, easy to change after the fact, and painful to pull together when an auditor asked a simple question: is every instrument in calibration, and can you prove it?
So the scope stayed narrow on purpose. Capture as-found and as-left readings at the bench on whatever device is already in your hand, judge them against tolerance automatically, and write every entry to a tamper-evident, hash-chained ledger with a two-person maker and checker signature. When a gage drifts, reverse-trace in one click to everything it measured, so containment is narrow and defensible instead of a blanket recall.
Axiospec is a documentation and workflow tool. It does not grant accreditation. It helps you produce clean, traceable, audit-ready records so an audit becomes a lookup instead of a scramble.
