Business logic stays yours. Ask your coding agent to add a guardrail — it adds guardrails/must-cite.ts and edits agent.ts, runs kindgi test, ships with kindgi deploy.
Kindgi's SDK is a handful of typed factories — defineAgent, defineTool, defineGuardrail, defineFlow — with policies like human-review declared inline on the agent. Your coding agent would know how to write them using types, CLI, and AI-native documentation — plus the same guardrails that run in CI run in production. Everything underneath — signed audit, kernel-level enforcement, running the review flow when your policy fires — is handled by Kindgi's runtime.
// agent.ts import { defineAgent } from '@kindgi/sdk/define' export const triage = defineAgent({ id: 'claims-triage', guardrails: [ 'must-cite', 'no-delete-claim', ], needs: ['structured_output'], })
// guardrails/must-cite.ts import { defineGuardrail } from '@kindgi/sdk/define' import { z } from 'zod' export default defineGuardrail({ id: 'must-cite', kind: 'zero-llm', configSchema: z.object({ min: z.number().default(1), }), evaluate: async ({ min }, trace) => { const cites = trace.output.citations ?? [] return cites.length >= min ? { passed: true } : { passed: false, reason: `${cites.length} < ${min}` } }, action: { 'on-violation': 'halt' }, })
Kindgi speaks your language, calls your models, and plugs into your infrastructure. It sits between what you already have and what you're about to build — never replacing either.
Type-checked TypeScript SDK today, Python and Go on the roadmap. HTTP and CLI for anything else. Kernel-level bindings to any model provider, any Postgres, any auth system, any secrets store, any sandbox. Everything swappable through a single bindings interface.
Runs on Postgres and any container runtime. Docker Compose on your laptop, Kubernetes in your VPC, or Kindgi Cloud when you'd rather not run ops.
One command on your laptop. Full runtime with Postgres, guardrails, and provenance. Standalone — no external services required.
Ships as a container image. Runs on Postgres and any container runtime — Kubernetes, ECS, GKE, or AKS. Zero telemetry back to Kindgi; keys, logs, and audit stay on your infrastructure.
Kindgi Cloud — same runtime, we operate it. For teams who want the audit story without standing up the ops. Public beta opens Q1 2027; private preview available on request.
Every output signed. Every reviewer decision recorded. Every guardrail enforcement logged.
Kernel-level guardrails, HITL as a first-class surface, Ed25519-signed provenance DAG. Downloadable audit bundle for compliance review, regulator inspection, or breach forensics. Verify signatures with any standard crypto library — no Kindgi runtime required.
See how it works →An AI-native developer experience. A seamless path from local to production. Nothing you don't need; everything swappable. Thoughtful, first-class kernel primitives: audit, human review, policy enforcement, capability routing, flow orchestration. One integrated runtime — transferable across models, providers, and deployments.
