The best ChatGPT plugins for developers (October 2026)
12 ChatGPT and Codex plugins and MCP servers worth installing as a developer: GitHub, Linear, Sentry, Vercel, Supabase, Stripe, Figma, Context7 and more.
The best ChatGPT plugins for developers in October 2026 are GitHub and Linear for code and issues, Sentry for production errors, Vercel, Supabase and Cloudflare for deploying and running apps, Stripe for payments, Figma for design-to-code, Codex Security and CodeRabbit for review, plus two MCP servers that every coding agent benefits from: Context7 for current docs and Playwright for browser testing. All of them work in Codex, and most also work in ChatGPT, because both products share one Plugin Directory.
Below is what each one does, what it bundles, and when to pick it.
How we picked#
We looked at the developer listings in our plugin and MCP directories and favoured:
- Official publishers. Every pick is built by the company behind the product or by OpenAI, except where noted.
- Plugins that bundle skills with the connection. A plugin that includes workflows (how to triage CI, how to write a migration) tends to be more useful than a bare connection.
- Clear scope. Tools you can limit to read-only or to one project score higher.
We have not run benchmarks. These are recommendations based on what each listing contains, as of October 4, 2026.
The list at a glance#
| Pick | Type | Best for | Bundles |
|---|---|---|---|
| GitHub | Plugin | PR triage, CI failures, publishing changes | App connection, MCP config, skills |
| Linear | Plugin | Issues, cycles, project updates | App connection, MCP config |
| Sentry | Plugin + MCP | Investigating production errors | Skill (plugin); OAuth server (MCP) |
| Vercel | Plugin | Next.js, AI SDK, deployments | Many skills, app connection |
| Supabase | Plugin | Postgres, auth, edge functions | App connection, skills |
| Stripe | Plugin | Payments integration and account data | App connection, skills |
| Figma | Plugin | Implementing designs in code | App connection, skills |
| Cloudflare | Plugin | Workers, Wrangler, MCP servers on Cloudflare | Skills, Cloudflare API MCP server |
| Codex Security | Plugin | Security scans and fix proposals | Skills, app connection, MCP config |
| CodeRabbit | Plugin | Reviewing local changes before a PR | Skill |
| Context7 | MCP server | Up-to-date library documentation | Remote or local server |
| Playwright | MCP server | Driving a real browser in tests | Local server |
To install plugins, see How to install plugins in ChatGPT or Use plugins in Codex. In the Codex CLI, /plugins opens the plugin browser. For the two MCP servers, see Add an MCP server to ChatGPT.
1. GitHub#
The GitHub plugin, built and maintained by OpenAI, combines a GitHub connection with a CLI workflow for inspecting repositories, triaging pull requests and issues, debugging CI and publishing changes. It is a good default for "why is CI failing on my branch?" or "triage the open PRs on this repo." OpenAI notes that its first-party GitHub app is required for some features, including Codex.
If you want more control over exactly which tools are exposed, GitHub's own MCP server lets you enable toolsets selectively.
2. Linear#
Linear's official plugin searches, creates and updates issues, projects and initiatives, and can draft PRDs and project updates. Use it to turn a bug found in a coding session into a ticket, or to ask what is in your team's current cycle. It is backed by Linear's hosted MCP server, which also offers a read-only endpoint if you only want lookups.
3. Sentry#
There are two ways to bring Sentry in. The plugin is built by OpenAI and wraps a Sentry skill for inspecting recent issues and events, which is handy for "which errors spiked after the last release?" The Sentry MCP server, run by Sentry at mcp.sentry.dev, uses OAuth, can be scoped to an organization or project, and searches issues, events and traces. If you want both the workflow and Sentry's full tool set, use the two together.
4. Vercel#
Vercel's plugin is one of the largest in the catalog. It bundles skills for Next.js, the AI SDK, AI Gateway, deployments and CI/CD, environment variables, functions, storage, firewall, feature flags and Turborepo, plus the Vercel app connection. Ask it to audit a repo for deployment risks, explain a failing build or roll back a deploy.
5. Supabase#
The Supabase plugin combines the Supabase app (run SQL, design schemas, deploy edge functions, configure auth, read logs) with skills for Supabase and Postgres best practices. A useful prompt: "Review my Supabase schema and RLS policies for security issues." For tighter control in Codex, Supabase's MCP server supports read-only mode and project scoping through URL parameters.
6. Stripe#
Stripe's plugin pairs the Stripe app (customers, products, prices, payment links, subscriptions, invoices, refunds and disputes) with skills such as Stripe best practices, docs search and upgrade guidance. It is useful both for building an integration and for checking account data. Because it can act on real money, connect a test-mode account while you develop and review every write. Stripe's MCP server requires human confirmation for sensitive writes such as refunds.
7. Figma#
Figma's plugin bundles the Figma connection with Figma's own skills for design-to-code, Code Connect templates, design system generation, FigJam and more. Point it at a frame and ask Codex to implement it, or generate Code Connect mappings for your component library. We use Figma to explain how plugins, apps and MCP servers differ in this explainer.
8. Cloudflare#
Cloudflare's plugin includes curated skills for Workers, Wrangler, Durable Objects, the Agents SDK, the Sandbox SDK and building MCP servers, plus the official Cloudflare API MCP server. It helps with "which Cloudflare product fits this?" and with deploying a Worker. If you only need documentation lookups, the separate Cloudflare Docs MCP server needs no authentication.
9. Codex Security#
OpenAI's Codex Security plugin runs security scans, diff scans and deep scans, builds threat models, triages findings, proposes and verifies fixes, and writes up vulnerabilities. Run a diff scan on a branch before you open a PR. At DevDay 2026 OpenAI added Codex Security Cloud, which scans connected GitHub repositories through a plugin; it is in research preview (DevDay notes).
10. CodeRabbit#
CodeRabbit's plugin ships a review skill that runs on your current or staged changes: "Review this branch before I open a PR." It is lighter than a full security scan and useful as a second pass on everyday changes.
11. Context7 (MCP server)#
Coding agents often reach for APIs that changed two versions ago. Context7, from Upstash, serves current, version-specific documentation and examples for thousands of libraries. It runs as a hosted server at mcp.context7.com or a local npm package, and uses a Context7 API key. OpenAI's own Codex MCP docs use it as an example: codex mcp add context7 -- npx -y @upstash/context7-mcp.
12. Playwright (MCP server)#
Microsoft's Playwright MCP server lets an agent drive a real browser through accessibility snapshots rather than screenshots: navigate, click, fill forms, read console messages and network requests, across Chromium, Firefox and WebKit. It runs locally (stdio), so use it from Codex or the ChatGPT desktop app, not ChatGPT on the web. Google's Chrome DevTools MCP server is an alternative when you need performance traces and Lighthouse audits.
Also worth a look#
- Expo: official skills for building, upgrading and deploying Expo and React Native apps.
- OpenAI Developers: skills for the Agents SDK, building and submitting ChatGPT apps, and API troubleshooting.
- PostHog: product analytics, feature flags and error tracking from your agent.
- Superpowers: a community skills plugin (by Jesse Vincent, listed in the curated Codex marketplace) for planning, test-driven development and systematic debugging.
- Trail of Bits supply-chain auditor: community security skills that audit npm, PyPI and Go dependencies; installs through Codex's marketplace support.
Before you connect#
Most of these plugins can write: open PRs, change issues, deploy, issue refunds. Start with read-only scopes where the service offers them, keep confirmations on for writes, and connect test or staging accounts first. Our plugin security checklist goes through each step.
