OpenComputer vs Tembo

Tembo (tembo.io) and OpenComputer both run Claude Code and Codex on cloud Linux machines, take requests from Slack, and hand back pull requests. Tembo gives each session a dedicated VM; OpenComputer gives each Slack workspace one machine, with each thread in its own copy of the repos on its own branch. Both let you bring your own Claude or ChatGPT subscription instead of paying for tokens.

The difference is breadth versus focus. Tembo is an agent orchestration platform: seven agent harnesses, dozens of models, triggers from Slack, Teams, Linear, Jira, GitHub, GitLab, Bitbucket, Sentry, schedules and an API, plus code review, billed from a monthly dollar allowance that covers VM compute and optional managed inference. OpenComputer is a coding agent you mention in Slack, built around a shared thread the whole team can steer, and billed per workspace for the minutes the agent actually works, with no user cap.

If you want one platform to route many agents and models across many tools, Tembo fits. If you want a teammate in Slack that turns requests into pull requests, OpenComputer fits.

At a glance

What is Tembo?

Tembo describes itself as an agent orchestration platform. Some search results still refer to the hosted Postgres product it was previously known for. Today, each session runs in a dedicated Linux VM, and no two sessions share one. Projects pre-build reusable environments as VM snapshots, so sessions restore instead of cloning and installing.

Tembo runs Claude Code, Codex, Cursor, OpenCode, Amp, Pi and fx, with per-task model routing. You can start a session from the dashboard, mention @tembo in Slack, Microsoft Teams, GitHub issues or PR comments, assign a Linear or Jira issue, or set up agents that run on schedules, integration events or a webhook. It opens PRs, including coordinated PRs across repos, exposes service ports as preview URLs, and has a live desktop for browser and GUI work. Tembo also has a desktop app, a CLI and an automated code review product, Tembo Review.

What is OpenComputer?

OpenComputer runs Claude Code and Codex in its own cloud, and you hand them work by mentioning @Computer in a Slack thread or calling the API from your code. Each Slack workspace gets its own cloud Linux machine, sized to its plan. Every thread works in its own copy of the repos on its own branch, so parallel requests don't collide. Workspaces resume warm, with the repository, dependencies and build caches already in place.

@Computer reads the code, runs the commands and tests, then opens a pull request that says what changed, why, and how it was checked, with a link back to the thread. UI changes come with a screenshot and a preview link. The same cloud runs serverless agents you write in TypeScript, on the minutes the team already pays for.

Key differences

Breadth of agents, models and triggers

Tembo offers more choice on every axis. It runs seven harnesses, lists models from Anthropic, OpenAI, Google, xAI and open-weight providers, and connects to all three major Git hosts, Slack and Teams, Linear and Jira, and tools like Sentry and Datadog. If your team uses several agents, GitLab or Bitbucket, or wants Jira tickets picked up automatically, Tembo covers that today. Niteshift takes a similar multi-harness approach.

OpenComputer does one job: Claude Code and Codex, started from Slack or the API, ending in a pull request. Recurring and event-driven work is something you build yourself as a serverless agent with schedules, webhooks and Slack, GitHub or Linear connections.

Dashboard sessions or a shared Slack thread

Tembo centers on the session in its dashboard, with a terminal, files, a Changes tab and a live computer you can watch. Slack is one of many ways in.

On OpenComputer the Slack thread is the product. Everyone in it sees every file @Computer opens and every command it runs, anyone can redirect it, and conventions one person explains apply to the next person's requests. The thread is also the record of who asked for each change and why. There is no IDE or desktop app.

Models and what you pay for them

Both support your own subscriptions. Tembo connects Claude, ChatGPT and SuperGrok subscriptions, API keys, and AWS Bedrock or Google Vertex AI, and also sells managed inference through Tembo Gateway at published per-token rates, drawn from your allowance. BYO inference costs nothing through Tembo, but VM compute is still billed.

OpenComputer offers your subscription, your own API key, or its tokens at API prices with no markup from prepaid credits. When a subscription hits its limit, you choose whether it switches to OpenComputer tokens until the reset or stops and waits.

Machines, compliance and hosting

Tembo lets you choose VM sizes from 2 vCPU up to 32 vCPU and 128 GiB, depending on plan, and documents self-hosted deployments on AWS, GCP, Azure and Kubernetes for enterprise customers. Its llms.txt states it is SOC 2 Type II certified. If those are requirements, Tembo has them documented. OpenComputer's core platform is open source under Apache-2.0.

Pricing compared

As of October 2026, Tembo lists Pro at $60 a month for up to 5 users and Max at $200 a month for up to 10 users, each with an equal dollar allowance, plus a free trial and custom Enterprise plans. VM compute is $0.0403 per vCPU-hour plus $0.0130 per GiB-hour, billed per second; a Medium VM (4 vCPU, 8 GiB) is $0.2652 an hour, and stopped VMs are not charged. Pro and Max can continue on overage with a spend limit. OpenComputer lists Pro at $20 a month with 2,000 work minutes and Max at $200 with 25,000, for the whole Slack workspace, and $0.01 per extra minute.

Take a team using its own Claude subscriptions for 30 hours of agent work a month on Medium VMs. On Tembo that is about $8 of compute, well inside Pro's $60 allowance, so the bill is $60. On OpenComputer, 1,800 minutes fits inside Pro at $20. At heavier use the picture shifts: Tembo Max's $200 allowance covers about 750 Medium VM-hours, while OpenComputer Max covers about 417 hours of work. The units differ, since Tembo bills while a VM runs and OpenComputer only while the agent is working. Team size matters too: Tembo caps users per plan, while one OpenComputer plan covers the whole Slack workspace.

When to choose Tembo

• You want to run several harnesses, such as Cursor, Amp or OpenCode, and compare models side by side.
• You use GitLab, Bitbucket, Microsoft Teams or Jira.
• You want each session isolated in its own dedicated VM.
• You need larger VMs, a live desktop for GUI work, self-hosting or SOC 2 Type II.
• You want automated code review from the same platform.

When to choose OpenComputer

• Your team works in Slack and wants requests, steering and history in one shared thread.
• You want pull requests with the evidence attached: what changed, how it was tested, and a screenshot for UI work.
• You want one plan for the whole workspace, with no per-plan user cap, priced by active agent minutes.
• You also want to build your own agents, such as a background coding agent, on the same cloud.

FAQ

Is OpenComputer a Tembo alternative?

Yes, for teams that mainly hand coding work to Claude Code or Codex from Slack. Both run agents on cloud Linux machines and return pull requests, though only Tembo gives each session its own VM. Tembo covers more agents, models and integrations, while OpenComputer centers on a shared Slack thread and per-workspace work minutes.

How much does Tembo cost?

As of October 2026, Tembo has a free trial, Pro at $60 a month for up to 5 users and Max at $200 a month for up to 10 users, each with a matching usage allowance, plus custom Enterprise plans. The allowance pays for VM compute, billed per second, and any managed inference through Tembo Gateway.

Can I use my Claude or ChatGPT subscription with both?

Yes. Tembo connects Claude, ChatGPT and SuperGrok subscriptions as well as API keys, and charges nothing for that inference, though VM compute is still billed. OpenComputer accepts your subscription or API key, and can switch to its own tokens at API prices when a subscription hits its limit, if you choose.

Is Tembo still a Postgres company?

Tembo was previously known for a hosted Postgres product, which still appears in some search results. The current tembo.io product is an orchestration platform for coding agents running in cloud VMs.

Does Tembo run in the cloud or on my machine?

Tembo runs each session in a dedicated Linux VM in the cloud. Its CLI can also pair your own machine as a device, a feature rolling out gradually, so a session you start can run commands and edit files on it. OpenComputer runs agents in its own cloud, on one Linux machine per Slack workspace.
