DEVELOPERS

Instrument once. Explain everything.

Three open-source SDKs and a plain HTTP API. Events follow one grammar — domain, entity, operation — so everything you capture composes into a single causal graph.

QUICKSTART

Your first event in five minutes.

Install @vectry/node, create a client with your API key, and capture your first structured event. The same grammar works from the browser with @vectry/js-core, from React with @vectry/react, or from anything that can POST JSON.

  • npm install @vectry/node — MIT licensed, TypeScript types included.
  • All SDKs are open source at github.com/vectry-analytics.
  • Fire-and-forget ingestion — capture never blocks your request path.
quickstart.js 
 import { Vectry } from '@vectry/node';

const vectry = new Vectry({
  apiKey: process.env.VECTRY_API_KEY,
});

await vectry.capture({
  namespace: 'auth.session.created',
  actor_id: 'usr-102',
  actor_type: 'user',
  operation: {
    type: 'created',
    system_domain: 'auth',
    system_entity: 'session',
    system_entity_id: 'ses-88f2',
  },
});
DATA MODEL

Five primitives, one graph.

Everything Vectry stores reduces to five primitives. Each carries multi-tenant scope, full audit metadata (created / modified / deleted with actor and timestamp) and a status lifecycle including archived and under-review.

Event observation
Atomic action, change or signal — actor + operation + context.
EventOperation embedded
Formal operation: type, system_domain, system_entity, system_entity_id, source, changes.
Trace execution
Localized flow of related events bound to one entity, with start/end.
CausalThread execution
Cross-system storyline grouping traces, closing with an outcome.
EventExplanation semantics
caused_by chain + human-readable narrative for one event.
Anomaly diagnostics
Expected vs actual pattern, deviation_score, level: event | trace | causal_thread.
HTTP INGEST

One endpoint for everything else.

No SDK for your stack yet? POST events to /v1/ingest with a Bearer token. That is the same wire contract the SDKs use — and the same one the Sommatic vectry.log worker emits through, so workflow events land in the identical graph as your application events.

  • POST https://api.vectry.io/v1/ingest — JSON body, Bearer auth.
  • Same grammar from backends, devices, workflows and pipelines.
  • Scoped API keys per organization and application.
DEVELOPER-FIRST

Instrument in minutes.

Open-source SDKs, one HTTP ingest API, and a data model you can read in an afternoon.

Explore the SDKs npm install @vectry/node
  1. 01

    Capture

    Emit structured events from backends, browsers and devices with the SDKs or plain HTTP.

  2. 02

    Thread

    Vectry binds events to traces and causal threads around your real entities.

  3. 03

    Explain

    Query the why: causal chains, narratives and anomalies over your operation.

quickstart.js 
 import { Vectry } from '@vectry/node';

  apiKey: process.env.VECTRY_API_KEY,
});

await vectry.capture({
  namespace: 'auth.session.created',
  actor_id: 'usr-102',
  actor_type: 'user',
  operation: {
    type: 'created',
    system_domain: 'auth',
    system_entity: 'session',
    system_entity_id: 'ses-88f2',
  },
});
