The agent harness for code, automation, and everything next.

Kepler is an agent runtime that ships production code today — and becomes the foundation for domain-specific AI workspaces tomorrow. Finance. DevOps. Data. Legal. Any vertical, same harness.

the platform

Three layers that work together. Use one, or all three.

01 — agent harness

The runtime that powers every Kepler agent. Multi-model orchestration with sub-agent spawning — an explorer reads, a planner designs, a coder implements.

◆Sub-agent architecture (explore → plan → code)

◆13 LLM providers, 40+ models

◆18+ built-in tools + MCP protocol

◆Human-in-the-loop approval

◆Sandboxed execution (Docker, Firecracker)

◆BYOK — your keys, your models, your data

02 — automations

Visual workflow builder. Drag agents onto a canvas, connect triggers and outputs, schedule recurring runs. Chain agents that pass context to each other.

◆Canvas editor with node graph

◆Template library (PR reviewer, code gen, etc.)

◆Cron scheduling + webhook triggers

◆Agent chaining with shared memory

◆GitHub, Slack, email, database adapters

◆Run history + cost tracking

03 — workspaces

Domain-specific agent environments. Build a workspace for any vertical — Finance, Legal, DevOps, Data — with custom tools, chat, and versioned outputs.

◆Custom plugin system (any domain)

◆Workspace UI: chat + tools + output panels

◆Versioned artifacts (Excel-like save/restore)

◆Domain-specific tool buttons

◆Team collaboration + role-based access

◆Connect your own data sources

build a workspace for any domain

Same harness, different plugins. Each workspace gets its own tools, data connections, output formats, and agent configuration.
