Short takeaways

Read this as a dated snapshot. Product access, plan names, model choices, and limits can change quickly.

01 / PR delegation

GitHub Copilot cloud agent and Claude Code GitHub Actions are strongest when the work starts and ends as issues, comments, branches, and pull requests.

02 / Local control

Codex CLI, Claude Code, and Cursor give developers the most direct terminal or IDE loop for inspecting diffs, running commands, and guiding edits.

03 / Enterprise backlog

Devin is positioned as an AI software engineer for parallelized, verifiable engineering tasks, especially migrations, maintenance, and ticket queues.

04 / App creation

Replit Agent is the most productized prompt-to-running-app path because planning, code, infrastructure, testing, and deployment live in one workspace.

05 / Selection rule

Choose by work surface first: GitHub backlog, local repo, cloud repo task, enterprise migration factory, or no-code app builder.

Offering Operating model Primary surfaces Best fit Watch-outs Source
OpenAI Codex Reads, edits, and runs code locally or in Codex cloud; cloud tasks can run in the background and in parallel. CLIIDEWeb/cloudGitHub Teams that want one OpenAI coding agent across local pairing, cloud delegation, and PR-oriented repo work. Cloud results still need human review, environment setup, and clear prompts; access depends on eligible ChatGPT plans and workspace policy. Docs
GitHub Copilot coding agent Autonomous GitHub Actions-powered cloud agent that researches, plans, edits on a branch, runs checks, and can open pull requests. GitHub.comIssuesVS Code entryAutomations GitHub-native teams that want to delegate backlog items and keep all work visible in branches, commits, logs, and PRs. GitHub-hosted repos only, one repo per run by default, hard 59-minute session limit, plus GitHub Actions minutes and AI credits. Docs
Cursor agent IDE-first agent that can plan, edit, run terminal commands, and operate through desktop, CLI, cloud, web, mobile, and team entry points. Desktop IDECLIWeb/mobileSlack/Linear Developers who want fast interactive editing, codebase-aware iteration, and a single agent surface across editor and cloud workflows. Best suited to developer-in-the-loop work; governance, repo access, and cloud-agent behavior should be validated against team needs. Product
Devin Autonomous AI software engineer for delegated engineering tasks; writes, runs, and tests code with emphasis on parallel enterprise workloads. CloudCLIDesktopLinear/Jira Organizations with many clear, verifiable tickets, migrations, refactors, and modernization tasks that can be split into isolated units. Needs crisp instructions and objective verification; broad or ambiguous tasks should be decomposed before delegation. Docs
Replit Agent Prompt-to-app builder that plans, creates projects, writes code, sets up infrastructure, tests, fixes issues, and publishes from Replit. Browser IDEDesign canvasDeployConnected services Founders, operators, students, and product teams turning natural-language ideas into working prototypes, apps, dashboards, or sites. Less specialized for existing enterprise codebases than repo-native agents; cost and capability vary by Agent mode. Docs

TerminalVS CodeWeb/desktopGitHub Actions Power users and teams that want customizable repo agents with MCP, CLAUDE.md instructions, skills, hooks, and PR automation. Power comes with configuration surface area; permissions, provider choice, and CI secrets need careful setup. Docs

Agent notes

Each card states the sharpest practical read, not a full vendor profile.

OpenAI Codex

Split local/cloud agent

Codex is now a multi-surface OpenAI coding agent: CLI for local repo work, IDE attachment for editor workflows, and Codex web/cloud for background tasks that can connect to GitHub and propose PRs.

  • Strong for mixed local development and delegated cloud tasks.
  • Useful when teams already standardize on ChatGPT and OpenAI accounts.

GitHub Copilot

GitHub-native PR agent

Copilot cloud agent is most concrete as a GitHub workflow primitive: assign an issue, start from the agents panel, or mention it in PR context, then review branch and PR output.

  • High transparency because work is visible through GitHub logs, commits, and PRs.
  • Clear limits make it better for scoped issues than sprawling changes.
GitHub source

Cursor agent

Editor-first agent network

Cursor's differentiation is continuity across the editor, CLI, cloud dashboard, browser/mobile, and collaboration entry points such as GitHub, Slack, Linear, and JetBrains IDEs.

  • Best when the developer wants to stay close to the edit loop.
  • Plan and agent modes make it practical for larger local tasks.

Devin

Autonomous software engineer

Devin is explicitly sold for ambitious engineering teams and complex codebases, with strong messaging around parallel task execution, migrations, modernization, bug reproduction, and backlog crushing.

  • Best when work can be decomposed into clear, testable units.
  • Enterprise fit is strongest for repetitive high-volume engineering programs.

Replit Agent

Prompt-to-product builder

Replit Agent is the broadest creation environment: it can refine the idea, create the app, write code, set up infrastructure, test the result, and publish artifacts from the same workspace.

  • Best for fast prototypes and complete small apps.
  • Agent 4 emphasizes design canvas work, collaboration, and parallel builds.

Claude Code

Configurable repo agent

Claude Code has grown beyond the terminal into IDE, desktop, browser, GitHub Actions, GitLab CI/CD, Slack, MCP, hooks, skills, background agents, and scheduled routines.

  • Best for teams that value programmable workflows and explicit repo instructions.
  • GitHub Actions support enables issue and PR automation through @claude.

How to choose

Selection heuristics

  1. For GitHub issue-to-PR delegation, start with GitHub Copilot cloud agent or Claude Code GitHub Actions.
  2. For terminal-heavy repo work, compare Codex CLI and Claude Code first, then Cursor CLI if the team already lives in Cursor.
  3. For IDE-centered daily coding, Cursor, Claude Code VS Code, and Codex IDE workflows deserve side-by-side trials.
  4. For migration factories and repeated enterprise maintenance, evaluate Devin with narrow tasks and hard verification gates.
  5. For nontechnical prompt-to-app creation, Replit Agent is the most complete default path.

Evaluation checklist

  • Can it run the same tests, linters, and setup commands a human engineer would run?
  • Does it expose plan, diff, command, and log history clearly enough for review?
  • Can repository instructions, memories, rules, or skills encode team standards?
  • Does its permission model match your data, network, and secret-handling constraints?
  • Can the team measure accepted PRs, reverted work, cost, time-to-merge, and review burden?
