Tembo alternative for always-on AI agents
Tembo runs coding agents task by task, each in a fresh VM that lives as long as the session. Molted runs autonomous agents that stay up between tasks.
Tembo is an agent orchestration platform for software work. It turns GitHub, Linear, Jira, Slack, Sentry or PagerDuty events into tested pull requests and runs Claude Code, Codex, Cursor, Amp or OpenCode in isolated cloud environments, on your own subscription if you want. Tembo Computer, launched in October 2026, gives every session a dedicated Linux VM with a 60fps desktop, a terminal and a file explorer, with VS Code, Chromium, gh, Docker and Postgres preinstalled. Compute is billed by the second at $0.0403 per vCPU-hour plus $0.0130 per GiB of RAM per hour, from a 2 vCPU, 2 GiB Nano at $0.1066 an hour to a 32 vCPU, 128 GiB Ultra.Molted is a managed operating environment for autonomous agents (OpenClaw today, Hermes and other runtimes on request). The agent lives in its own instance around the clock and the runtime, its recovery, versioned state, integrations and identity are operated for you.If the job is a reviewed pull request, Tembo is built for it. If the job is an agent that keeps working once the task is done, that is what Molted runs.

Lifecycle
TemboPer session. Tembo's docs describe sandboxes as ephemeral: spun up for the session and destroyed when it is done, with keep-alive available on demand.
MoltedAlways-on instances with a heartbeat: the agent keeps watching and acting on its own.
Machine
TemboDedicated Linux VM per session with nested virtualization for Docker-in-Docker, 50 to 200 GB of disk and up to 128 GiB of RAM.
MoltedCompute benchmarked for OpenClaw, cold starts around 1.1s, with per-agent resource limits.
The agent
TemboCoding agents (Claude Code, Codex, Cursor, Amp, OpenCode) started by an issue, an alert, a schedule or an @Tembo mention, with human approval on the result.
MoltedThe runtime is the product: a supervising daemon outlives the agent process and configs are auto-repaired.
Recovery
TemboPer task: a failed session is retried or revised from review feedback.
Molted4-tier self-healing: crashes caught in under 60s, back in under 90s, post-mortem on every failure.
State
TemboRepositories are cloned per session and torn down afterwards; project snapshots cache repositories and dependencies to speed up setup.
MoltedVersioned filesystem with file-level diff and point-in-time restore that hot-reloads the running instance.
Integrations and identity
TemboGitHub, GitLab, Bitbucket, Linear, Jira, Slack, Sentry, PagerDuty and MCP servers, focused on the software delivery loop.
Molted1,500+ integrations, managed browser automation (captchas, rotating geo-aware proxies, logged-in profiles) and a dedicated mailbox and phone number per agent.
Deployment
TemboTembo cloud, or self-hosted on AWS, GCP, Azure or Kubernetes. SOC 2 Type II.
MoltedManaged regions in the EU and North America, on-premise deployment and a dedicated Swiss option.
Best for
TemboEngineering teams that want coding agents to turn tickets and alerts into reviewed pull requests.
MoltedAutonomous agents that must stay up and act across real tools for a business or its clients.
02The part nobody else builds
One OpenClaw is hard to keep alive. Thousands is impossible without recovery.
A single OpenClaw in production already fails in quiet ways: it crashes and stays down, a config corrupts and bricks the instance, memory spikes and the whole box goes with it. Run thousands of them and doing this by hand is not hard, it is impossible. You need watchers and recovery running every second. Tembo does not ship any of this. Like every general cloud, machine or agent framework, it hands you infrastructure, not a system that watches your agents and brings them back. Molted is that system.
02
Clean recreation
If the instance itself fails, it is recreated automatically, with its state intact.
03
Known-good restore
openclaw doctor repairs corrupted configs and the versioned filesystem restores a last known-good state.
04
Critical alert
If automated recovery cannot fix it, a critical alert fires with a full post-mortem of the failure.
On top of the four tiers, per-agent resource limits keep one busy agent from taking the others down. Crashes are caught in under 60 seconds and back online in under 90, with a post-mortem on every failure.
03Why Molted
The detail behind the table.
What Tembo is genuinely great at
Tembo is one of the most complete products for putting coding agents to work inside an engineering team. It listens where work already happens (issues, alerts, Slack threads, PR comments), runs the agent of your choice on your own subscription and hands back a pull request with logs, screenshots and a running preview. Multi-repo changes, scheduled maintenance and dependency upgrades are first-class use cases.
Tembo Computer makes that loop easier to trust. Every session gets a real Linux VM with a desktop you can open at 60fps, so you can click through what the agent built instead of reading logs. Self-hosting on AWS, GCP or Azure and SOC 2 Type II cover most enterprise reviews.
Built around the session
Everything in Tembo starts and ends with a task. Its documentation describes sandboxes as ephemeral: the VM is created for the session and destroyed when the session is done and only project caches survive. Billing follows the same shape, per second while the VM runs, which is ideal for a burst of work and expensive for a machine that never stops: about $96.80 of compute a month for a 2 vCPU, 4 GiB VM at list rates.
An autonomous agent works the other way round. It waits for an email, watches a system, follows up next week and keeps its memory between all of it. Molted is built for that shape: a supervising daemon that outlives the agent, 4-tier self-healing with a post-mortem on every failure, config auto-repair, a versioned filesystem with point-in-time restore, 1,500+ managed integrations, managed browser automation and a mailbox and phone number per agent.
Where each one fits
Use Tembo when the output is code: a ticket becomes a branch, a VM runs the build and the tests, a human reviews the pull request. Use Molted when the output is ongoing work: an agent that runs every day, answers channels, watches systems and acts on its own, for you or for your clients, with EU, US, on-premise or Swiss deployment.
The two fit together. A Molted agent can open the ticket that Tembo turns into a pull request, then keep following the work after it ships.
The verdict
Tembo is a strong platform for coding agents: events in, tested pull requests out, a full Linux VM with a live desktop for every session and per-second compute pricing. Molted is the operating layer for agents that never clock out: always-on instances with 4-tier self-healing, versioned state, 1,500+ integrations, browser automation, per-agent identity and on-premise options. Pick Tembo for agent-written code; pick Molted for agents that run themselves.
04FAQ
Tembo alternative, answered.
01Is Tembo cheaper than Molted?
For short sessions, often yes: Tembo bills VM compute by the second at $0.0403 per vCPU-hour and $0.0130 per GiB-hour and stopped VMs cost nothing, per its October 2026 pricing. For an agent that runs all month, the same rates add up to about $96.80 for a 2 vCPU, 4 GiB VM, before the plan fee. Molted prices per agent instance per day and includes the operating layer: recovery, versioned state, integrations, browser automation and identity.
02Can I run OpenClaw or Hermes on Tembo Computer?
Tembo Computer is a full Linux VM, so you can install them. It is designed around coding sessions though: a resident agent needs keep-alive, is billed for every running hour and leaves supervision, recovery, state versioning and integrations to you. On Molted those are the product.
03Does Tembo keep state between sessions?
Not by default. Tembo's docs describe sandboxes as ephemeral: repositories are cloned for the session and torn down afterwards. Projects can cache repositories and dependencies in reusable snapshots to speed up setup. Molted keeps every agent's files on a versioned filesystem with point-in-time restore.
04When should I pick Tembo over Molted?
When you want coding agents to turn issues and alerts into reviewed pull requests across your repositories, with a VM per task. Pick Molted when you need autonomous agents running in production around the clock without building and staffing the operating layer.
