The 6 best cloud coding agents for engineering teams in 2026
Published September 12, 2026
Summary
Compare Replicas, Devin, Cursor, Tembo, Codex, and Claude Code by workflow fit, hosted execution, setup requirements, and the evidence available for review.
Cloud execution
Choose where delegated engineering work will run
Replicas, Devin, Cursor, Tembo, Codex, and Claude Code can all handle coding tasks in hosted environments. Start with the job: give an agent repository context, let it implement and verify a change, then review the result. Replicas is a strong fit when you want to delegate that work from Slack or Linear while choosing the coding agent that runs it.
Replicas publishes this guide. The comparisons use linked vendor documentation, checked September 9, 2026; they are not results from a controlled benchmark. Evaluate the hosted surface of each product because its local CLI or editor may have different capabilities.
| Product | Consider it for | Check in your trial |
|---|---|---|
| Replicas | Managed SaaS for task-to-PR engineering work, with a choice of coding agents | Repository setup, agent credentials, review evidence, and workflow triggers |
| Devin | A packaged autonomous engineering workflow | Environment preparation, task scoping, and how you steer and review sessions |
| Cursor | Remote agent work connected to the Cursor editor | Cloud Agent setup, review artifacts, and usage pricing |
| Tembo | Cloud execution with several supported coding agents | Agent availability, integrations, and the deployment you need |
| Codex | Hosted tasks using the Codex agent | Cloud environment setup and GitHub review workflow |
| Claude Code | Hosted tasks using Claude Code | Web environment access, repository setup, and session handoff |
Product comparison
Six cloud coding agents and when to choose them
Replicas: delegated engineering with a choice of coding agents
Choose Replicas when you want to hand off engineering work from Slack or Linear, keep using coding agents such as Claude Code or Codex, and review the results in one shared workspace. Replicas provisions and operates the cloud workspaces in its managed SaaS service. Agents can implement changes, run checks, and open pull requests; investigations can return findings instead.
The published Replicas backlog experiment shows this workflow on a real maintenance task. For REP-503, a batch of React lint fixes, the agent started the app in its sandbox and checked it before opening the PR. The experiment also records failed tasks and follow-up work. It used our own codebase and human grading, so it is evidence of the workflow rather than a benchmark against the other products here.
The strongest reason to shortlist Replicas is that combination of task delegation, agent choice, and verification in a running environment. Your team still prepares repository access, dependencies, and agent credentials, then reviews the changes and evidence before merging. If you prefer to standardize on one agent ecosystem, compare the Devin, Cursor, Codex, and Claude Code workflows below.
Devin: a packaged engineering workflow
Devin provides a managed environment for planning, implementing, testing, and returning changes for review. Shortlist it alongside Replicas when you want to delegate engineering tasks. Compare environment setup, human interventions, and the resulting pull request; do not infer task quality from whether a product supports multiple coding agents.
Cursor Cloud Agents: editor-connected cloud work
Cursor Cloud Agents run in isolated VMs and can use a browser, run software, and return review artifacts. Shortlist Cursor when connecting local editor work with remote tasks is useful. Check the cloud setup, network access, and usage costs for the workload you intend to delegate.
Tembo: cloud execution across several coding agents
Tembo supports multiple coding agents, including Claude Code, Codex, and OpenCode. It belongs in the same cloud-agent shortlist as Replicas. Check the current agent catalog, integrations, credential options, and deployment terms rather than assuming that agent choice is unique to one platform.
Codex cloud: hosted work with the Codex agent
Codex cloud runs delegated repository tasks in OpenAI-hosted environments and provides changes for review. Evaluate environment setup, dependencies, network requirements, and how the result moves into your GitHub workflow. The hosted service and local Codex CLI are separate execution options.
Claude Code on the web: hosted Claude Code sessions
Claude Code on the web runs repository tasks in an Anthropic-managed environment. Consider it when the Claude Code workflow fits your team and you want hosted execution. Verify repository access, environment setup, and the available paths for moving work between web and local sessions.
Evaluate
Test the environment as well as the agent
- Assign the same scoped feature or reproducible bug to each finalist from the same repository snapshot.
- Verify that dependencies, private packages, databases, and test services can run in the task environment.
- Inspect changes, command output, tests, and browser evidence. Record the human time needed to get the result ready for review.
- Check repository permissions, secrets, network access, retention, and deployment requirements for the plan you would buy.
- Record total platform, runtime, and inference cost for the trial. Bring-your-own credentials do not by themselves prove lower cost.
Working model
When a local coding agent is enough
If one developer is working interactively in a prepared repository, a local CLI or editor agent may cover the task. Hosted execution becomes useful when work should continue independently, several tasks need separate environments, or the team needs a shared place to inspect progress and results.
