Herdr is a terminal-native agent multiplexer — every coding agent at a glance, real terminal views, detach and reattach anywhere without losing sessions.
Key features
- Agent Multiplexer: See every running coding agent at once with real terminal views — blocked, working, or done — instead of wrapped or interpreted output.
- Detach and Reattach Anywhere: Sessions survive restarts and can be reattached from any terminal or over SSH so long-running agents keep working in the background.
- Socket API for Agents: A pure socket API lets agents themselves spawn panes, read output, and wait on each other, with a documented agent-skill.
- Keyboard + Mouse First Class: tmux-style prefix keys plus click, drag, and split — pick whichever interaction fits the moment.
- Plugin Marketplace: Extend panes and workflows with plugins from the herdr.dev plugin marketplace.
- Single Rust Binary: Distributed as one Rust binary (no Electron), installable via curl script, Homebrew, or mise, with a Windows PowerShell beta.
Best for
- Coding Agent Fleet Management: Watch a swarm of Claude, Codex, or Cursor agents in one dashboard while they work on different repos.
- Long-Running Agent Jobs: Kick off multi-hour agent tasks, detach, and reattach from a laptop later to check status without losing progress.
- Remote Development: SSH into a workstation and reattach the exact multiplexer session, so agents keep running on the server between sessions.
- Agent-to-Agent Orchestration: Use the socket API so one agent can spawn sub-agents in new panes and wait on their output.
- Terminal-Centric Workflows: Replace ad-hoc tmux + shell tricks with a purpose-built multiplexer that understands agent lifecycles.
Solarch
Solarch
Visual backend architecture tool: draw node/edge graphs, validate with a rules engine, and generate matching backend code to prevent architectural drift.
Key features
- Live Graph Editor: A node-and-edge visual editor for composing backend architectures (services, data stores, connections) with live feedback and manipulation.
- Rules Engine Validation: Built-in validation rules that check the drawn architecture for policy, best-practice, and safety violations before code generation.
- Automated Code Generation: Generates scaffolded backend code that directly matches the validated architecture, reducing manual translation work.
- Architecture-Code Parity: Keeps diagrams and generated code in sync to prevent architectural drift and ensure the implementation follows the approved design.
- Scaffold Customization: Produces customizable starter code and project structure so teams can iterate from a working baseline rather than from scratch.
- Design-as-Source-of-Truth: Treats architecture diagrams as the authoritative specification, enabling governance, review, and reproducible builds from the visual model.
- Live node/edge graph editor for backend architecture
- Rules engine to validate architecture diagrams against constraints
- Automated code generation that produces backend code matching the diagram
- Prevents architectural drift by keeping design and code in sync
- Visual-to-code workflow enabling design-driven development
Best for
- Designing Microservice Backends: Visually model microservice boundaries, communication paths, and data stores, then generate matching service scaffolds to accelerate implementation.
- Onboarding and Handoff: Provide new engineers with a validated visual architecture plus generated starter code so they can quickly understand and contribute to the system.
- Enforcing Architecture Governance: Apply organizational rules in the validation engine to ensure new designs comply with standards before code is produced.
- Prototype-to-Production Acceleration: Rapidly iterate on architecture diagrams and produce working code prototypes that can be extended into production systems.
- Refactoring and Reconciliation: Use the visual model to plan refactors and produce updated scaffold code that brings implementation back into alignment with the intended architecture.
- Documentation-as-Code: Maintain diagrams as the source of truth and regenerate code or artifacts to keep documentation and implementation synchronized.
- Designing backend system architecture as diagrams and generating initial code scaffolding
- Enforcing architectural constraints across teams via automated validation
- Keeping infrastructure-as-code and implementation consistent with architecture diagrams
- Generating API or service stubs from a validated architecture graph
- Onboarding and documentation through visual architecture artifacts tied to code
