Autonomy-aware runtime.
Runs autonomous workloads across cloud, edge, on-device, and on-robot — with first-class awareness of tokens, models, memory, and embodiment.
What it is
Hearth is where autonomous actors execute. It schedules, runs, and supervises actors across heterogeneous compute with awareness of the dimensions that distinguish autonomous workloads from generic ones: token budgets, model availability, tool dependencies, memory lifecycle, latency objectives, embodiment constraints. Every actor runs under a budget, a model routing policy, a memory binding, and a safety envelope. The runtime enforces them. Built on durable execution: when a process crashes, work resumes from the last checkpoint — state is never lost.
The problem
Generic schedulers are blind to the dimensions that determine whether an autonomous workload succeeds. Kubernetes does not understand token budgets. Lambda does not understand provider fallback. Robotics middleware does not understand cost ceilings. Operators are left running autonomous workloads on infrastructure designed for stateless requests, with autonomy-specific concerns built into application code, inconsistently, across every team.
Capabilities
Open and commercial
Hearth is delivered through two surfaces: an open-source reference in Lattice Runtime (MPL 2.0), and a managed, enterprise-grade delivery in Visca Cloud. Features in the open never move behind the paywall.

Data model as code.
The declarative primitive for your data model. Agents write it as source; humans edit it as a spreadsheet. Plan, apply, drift-detect.
Reproducible bundles for autonomous actors.
Immutable, content-addressed, Sigil-signed bundles. Everything an autonomous actor needs to execute, packaged as a single attestable artifact.
The developer surface.
Where developers build autonomous systems. CLI, SDKs, local runtime, eval harness, replay, documentation, templates — one surface.
Across the platform
Cryptographic identity for autonomous actors.
Issues, verifies, and revokes the cryptographic identity every autonomous actor holds — bound to principal, runtime, and lineage from the moment of instantiation.
Zero-trust access for autonomous actors.
Brokers every access from an autonomous actor to a consequential resource — identity-bound, scoped, time-limited, audited. Long-lived credentials disappear.
The autonomic fabric.
Discovery, mTLS, and routing across every autonomous actor and every resource an actor reaches — rooted in Sigil identities, not hardcoded URLs.
The system of record.
A queryable knowledge graph of every autonomous actor in the estate — and the append-only, cryptographically chained audit of every action taken.
The autonomy economy is shipping
Build, run, and trust autonomous systems on an integrated platform — software, embodied, and hybrid. Open foundation. Enterprise cloud. No license rug-pulls, ever.
