The platform

Oneruntimeforeveryintelligentsurface.

plainhand is the connective tissue between models, data and product. It turns brittle prompts and orphan scripts into a fleet of governed, observable agents — shipped on the same control plane your team already knows.

Unified runtime

One execution surface for agents, tools, and models. No glue code, no duct tape.

Composable layers

Stack memory, retrieval, planning and execution as drop-in primitives.

Enterprise posture

SOC 2, PII redaction, regional residency and per-tenant isolation by default.

Versioned everything

Prompts, tools and policies are first-class artifacts with diffs and rollbacks.

Live observability

Trace every token, span and tool-call. Replay any run, any time.

Adaptive routing

Cost, latency and quality budgets met automatically across 50+ models.

Architecture

A stack that composes itself.

Interface · React, REST, gRPC, MCP
Orchestration · planner, scheduler, retries
Execution · tools, sandboxes, agents
Models · 50+ providers, multi-modal
Foundation · vector store, telemetry, vault
