Best ForDevelopers running multiple coding agents in one terminalTeams building reliable AI agents and multi-step workflows

Temporal AI and Herdr serve fundamentally different needs: Temporal is a production-grade orchestration platform for mission-critical, multi-step AI workflows that require durability and reliability; Herdr is a lightweight terminal multiplexer for running several AI coding agents side-by-side with session persistence. Choose Temporal if you need to build robust agent pipelines or microservices orchestration; choose Herdr if you want a 'tmux for AI agents' to manage multiple coding assistants from one terminal.

Features
Runs coding agent CLIs as persistent background servers that survive sleep, close, and reboot
Reattach to live agent sessions over SSH from any machine
Real PTY-backed terminals instead of tmux or screen multiplexing
Per-pane agent status: working, blocked, or idle
Agent-native CLI and local JSON socket API — the same surface agents drive
Agents split panes, start each other, prompt each other, and wait on a blocked peer
22 agent CLIs detected out of the box
Supports Claude Code, Codex, Cursor, opencode, Grok, Copilot, Hermes, and Pi
Version 0.9: local and remote machines in one TUI client with a combined agent list
Add remote machines over SSH with independent reconnects per machine
Single Rust binary for macOS, Linux, and Windows (beta), Apache-2.0 licensed
No account and no telemetry required
Installs via curl, Homebrew, Nix, or the Windows install script
Session state: detach, restart restore, pane history replay, and native agent resume
Live server updates replace without killing running pane processes
Durable execution captures Workflow state at every step with no checkpointing or recovery code
Native SDKs for Go, Java, Python, TypeScript, .NET, PHP, Ruby, and Rust
Activities retry automatically with backoff, four timeout classes, and heartbeating
Signals, Queries, and Updates read and mutate running Workflows mid-flight
Workflow Streams for real-time interactivity with running executions
Durable AI agents via OpenAI Agents SDK and Google ADK running LLM and tool calls as Activities
Serverless Workers host durable AI agents on Amazon Bedrock AgentCore
Serverless Workers on AWS Lambda (public preview) and GCP Cloud Run (pre-release)
Standalone Activities as a durable job-queue pattern, GA across six SDKs (2026-09-15)
Native Task Queue priority and fair distribution without a custom queueing layer
Durable Timers sleep for months; cron Schedules support backfill and Continue-As-New
Saga pattern via compensating transactions that read like try/catch
Worker Versioning pins Workflows to a version so deploys don't corrupt in-flight runs
Cloud UI Strict Session Mode enforces 15-min inactivity timeout and 12-hour max session (GA 2026-09-18)
Replay tests validate against real histories; time-skipping tests fast-forward long timers in CI

What real users say: Herdr vs Temporal AI

Not marketing copy and not our opinion — a structured sweep of public discussion (reviews, forums, communities and video comments), showing what people praise and what they complain about for each tool.

Herdr

45 mentions across 2 sources · 69% positive (averaged across 2 sources)

Hacker News, Lemmy

What users praise

  • • Persistent agents survive laptop close, reboot, and network drops.
  • • Reattach from any SSH-capable device, including phone.
  • • Real PTY per agent, not tmux/screen multiplexing fakes.
  • • Visual agent status (working, blocked, idle) at a glance.

What frustrates them

  • • Steep learning curve for tmux/nvim veterans.
  • • Windows support is beta and may be buggy (WSL issues).
  • • Docs confusing about model provider support (e.g., Vercel AI gateway).
  • • Missing customization options (colors/font/sizing) for daily-driver use.

Temporal AI

No verifiable community signal. We scanned public discussion on Oct 14, 2026 and found posts matching the name “Temporal AI”, but could not establish that they are about this product rather than something else sharing its name. Rather than publish a score built on the wrong subject, we publish none.

Who should pick which

  • Engineering team building AI assistants with crash tolerance
    Pick: Temporal AI

    Temporal's durable execution ensures workflows survive failures, with human-in-the-loop support and integrations with OpenAI Agents SDK and Google ADK.

  • Individual developer running multiple Claude Code instances
    Pick: Herdr

    Herdr lets you run and monitor several coding agents in one terminal with persistent sessions and SSH reattach from any device.

Frequently Asked Questions

Herdr vs Temporal AI: which should you choose?

Temporal AI and Herdr serve fundamentally different needs: Temporal is a production-grade orchestration platform for mission-critical, multi-step AI workflows that require durability and reliability; Herdr is a lightweight terminal multiplexer for running several AI coding agents side-by-side with session persistence. Choose Temporal if you need to build robust agent pipelines or microservices orchestration; choose Herdr if you want a 'tmux for AI agents' to manage multiple coding assistants from one terminal.

Can Herdr orchestrate multi-step workflows with retries?

No, Herdr is only a terminal multiplexer. It does not provide workflow orchestration, durability, or retries.

Does Temporal AI integrate with Claude Code?

Temporal's integrations focus on agent SDKs and services (OpenAI, Google ADK, Slack). There is no direct integration with Claude Code listed.

Can I use Herdr to run agents on remote servers?

Yes, Herdr supports an SSH bridge to run agents on remote boxes and can be reattached via SSH from any device.

Is Temporal AI free to use?

The open-source Temporal Server is free. Temporal Cloud offers a free tier with usage-based billing for additional usage.

Does Herdr require an account or collect telemetry?

No, Herdr requires no account and has no telemetry. It is fully self-hosted.

What SDKs does Temporal support?

Multiple SDKs including Python, Go, TypeScript, Ruby, C#, Java, PHP, and Rust (public preview).

Can Herdr run non-coding agents?

Technically it can run any terminal program, but it is designed for AI coding agents (Claude Code, OpenCode, Codex).

Does Temporal provide a visibility UI?

Yes, Temporal includes a full visibility UI to inspect execution state and history.
