OUR STORY

Appear is winding down. The idea continues at ctxpipe.ai.

We built Appear to automate API schema lifecycle management. That product is being wound down. The next step is ctxpipe.ai — an engineering context layer for your whole org, not just your APIs.

From API schemas to org-wide context

Appear started from a simple observation: API schemas and documentation were still largely manual, error-prone, and out of date. We had lived that problem from both sides — in the teams responsible for the APIs, and in the trade-off between technical debt and customer value.

We built an introspector-agent platform to discover real API behaviour, keep OpenAPI and JSON Schema accurate, and feed reliable contracts to engineers and AI agents. That work taught us the constraint was larger than APIs. Agents fail when they lack the rest of the organisation's knowledge: code, ADRs, skills, issues, docs, outages.

ctxpipe is that next step: a self-learning knowledge graph for the whole engineering org, with one MCP connection for every coding agent. Appear the product is winding down. The free tools and references we shipped along the way stay here.
