GitHub Copilot vs Codeium (Devin Desktop) vs Tabnine vs Replit: AI Coding Tools Compared 2026

Last Updated: November 1, 2026

GitHub Copilot is the best default for most developers and teams in November 2026: Copilot Pro costs $10 a month, Copilot Business costs $19 per seat, and it plugs into VS Code, Visual Studio, JetBrains IDEs, Eclipse, Xcode and Neovim. Choose Tabnine if your code cannot leave your own servers, and choose Devin Desktop, the product that started life as Codeium and later became Windsurf, if you want an agent-first editor.

Codeium no longer exists under that name. The Codeium company renamed itself Windsurf on April 4, 2025, Cognition (the maker of the Devin coding agent) bought Windsurf in July 2025, and on June 2, 2026 Cognition renamed the Windsurf editor to Devin Desktop. Anyone searching for "Codeium" today is looking for Devin Desktop, or for the older Windsurf plugins that still exist for JetBrains IDEs.

The rest of this comparison uses "Devin Desktop" for the current product and "Windsurf" or "Codeium" only when talking about its history. Replit stays in the comparison because many teams shortlist it alongside these three.

GitHub Copilot wins on price and editor coverage, Devin Desktop wins on agent workflows, Tabnine wins on private deployment, and Replit wins on zero setup. The table below uses prices taken from each vendor's own pricing page on November 1, 2026.

Prices come from the GitHub Copilot plans page and GitHub Docs, the Devin pricing page, the Tabnine comparison page and Tabnine deployment documentation, and Replit pricing documentation. For a deeper look at Copilot's credit system, see our GitHub Copilot pricing guide.

These four tools solve different problems, so the right pick depends on your constraints more than on raw features. GitHub Copilot is an add-on to the editor you already use, Devin Desktop is a full editor built around agents, Tabnine is built around keeping code private, and Replit is a cloud workspace that removes local setup entirely.

GitHub Copilot has the scale advantage. iTWire reported that Microsoft disclosed more than 4.7 million paid Copilot subscribers in its January 2026 earnings, up 75 percent year on year. Our GitHub Copilot statistics page tracks the newer adoption numbers.

GitHub Copilot now includes inline suggestions, chat, agent mode, a command line tool and a coding agent that can take an issue and open a pull request, all starting at $10 a month on Copilot Pro. GitHub Copilot had more than 4.7 million paid subscribers as of Microsoft's January 2026 earnings.

How GitHub Copilot works: Copilot installs as an extension in VS Code, Visual Studio, JetBrains IDEs, Eclipse, Xcode and Neovim, according to GitHub's Copilot feature matrix. Neovim support covers code completion only; chat, agent mode and MCP are not listed for it. On every individual plan, Copilot users can pick from models by Anthropic (Claude), OpenAI (GPT), Google (Gemini), xAI (Grok), Microsoft (MAI), plus Kimi K3.

Why developers choose GitHub Copilot: Copilot works inside the editor a team already uses, so there is no migration, no new keybindings and no second tool to approve with security. For companies that already host code on GitHub, Copilot also ties directly into issues, pull requests and code review.

GitHub Copilot for teams: Copilot Business costs $19 per granted seat per month and Copilot Enterprise costs $39 per granted seat per month, per GitHub Docs. GitHub says the two business plans differ in total AI credits and available models, and admins set usage limits for each.

GitHub Copilot limitations: Copilot runs as a cloud service, and GitHub's plan pages list no self-hosted or air-gapped option, so it needs an internet connection and code context is processed in GitHub's cloud. Usage is now metered in GitHub AI Credits (1 credit equals $0.01), which means heavy agent users can exceed their included allowance and pay for more.

GitHub Copilot pricing: Free includes 2,000 inline suggestions a month plus limited chat and agent usage. Pro costs $10 a month and includes $15 of AI credits. Pro+ costs $39 a month with $70 of credits, and Max costs $100 a month with $200 of credits. Pro+ and Max can also delegate work to third-party agents such as Claude and OpenAI Codex (in preview), according to the GitHub Copilot plans page.

Devin Desktop is the current name of the editor that began as Codeium and was later called Windsurf. Cognition announced on June 2, 2026 that Windsurf would become Devin Desktop, a full IDE with an agent manager built in, and that existing plans, pricing, extensions and settings would carry over through a normal update.

How Devin Desktop works: Devin Desktop keeps the VS Code-style editor, and the Cognition blog says its editor, extensions, keybindings and language servers stay backwards-compatible with Windsurf and VS Code. The bigger change is Devin Local, a local agent rewritten in Rust that Cognition says is up to 30 percent more token efficient than Cascade, the Windsurf agent it replaced. Cascade remained available through July 2026 so teams could migrate gradually.

Why developers choose Devin Desktop: Devin Desktop is built for running several agents at once. The Devin Desktop product page describes a command center with Spaces, a Kanban view, local and cloud sessions you can move between, a built-in diff reviewer called Devin Review, and support for the Agent Client Protocol so you can manage third-party agents from the same window. Tab completions are unlimited on every plan, including Free.

How Devin Desktop usage works: Each Devin Desktop plan comes with a usage quota rather than a fixed number of requests, and paid plans can buy extra usage at API pricing once the quota runs out. The Devin pricing page does not publish exact quota numbers, so teams that lean hard on agents should watch their first month of spend closely. For usage and growth figures, see our Windsurf statistics page.

Devin Desktop for enterprises: The Enterprise plan is custom priced and lists SSO, VPC deployment and a dedicated deployment option. The Devin Desktop FAQ confirms legacy Windsurf Enterprise plans continue unchanged. Devin Desktop runs on macOS, Windows and Linux, while the Windsurf plugin for JetBrains is now in maintenance mode, with Cognition steering JetBrains users toward Devin over the Agent Client Protocol.

Devin Desktop pricing: Free costs $0 with a light agent quota and unlimited Tab completions. Pro costs $20 a month and Max costs $200 a month. Teams costs $80 a month for the team plus $40 a month per full developer seat, for up to 200 users. Enterprise pricing is custom.

Yes. Tabnine is the strongest pick in this comparison for teams that cannot send code to a vendor's cloud, because it can run in your own VPC, on your own servers, or fully air-gapped. Those private installations are an Enterprise feature; the hosted SaaS version is what Pro customers use, according to the Tabnine deployment documentation.

How Tabnine works: Tabnine installs as an extension in VS Code, JetBrains IDEs, Visual Studio, Eclipse, Neovim and other editors, per the Tabnine comparison page. Tabnine provides code completions, chat and agent features, and its Enterprise deployment lets a company keep the whole system inside its own network.

Why regulated teams choose Tabnine: Tabnine lists SOC 2 Type 2 compliance, says its platform is aligned with GDPR, HIPAA and ITAR, and applies a zero data retention policy to both code and usage metrics. For banks, healthcare providers and defense contractors, those controls often decide the purchase before features are compared.

Tabnine deployment options: Tabnine offers four ways to run: Secure SaaS hosted by Tabnine, a VPC install on AWS, Google Cloud or Azure, an on-premises Kubernetes cluster, and a fully air-gapped install. Tabnine's documentation states that in a VPC install "Tabnine doesn't have access to the customer environment."

Tabnine trade-offs: A private Tabnine install means your team runs and updates the cluster, which takes DevOps time that SaaS tools like GitHub Copilot do not need. Teams that do not have a hard data residency requirement usually get more for less effort from Copilot.

Tabnine pricing: Tabnine currently sells a Pro plan (labelled the Dev plan) with a 14-day free trial, plus an Enterprise plan priced through sales. Tabnine does not list Pro or Enterprise prices on the comparison and documentation pages we checked, so confirm the current figure on tabnine.com before you budget.

Replit is a cloud workspace rather than an editor plugin, so it suits people who want to build and publish an app without installing anything. Replit fits prototypes, classrooms, internal tools and non-engineers better than it fits large production codebases.

How Replit works: Replit Agent takes a plain-English description and builds and publishes the app inside Replit's cloud. The Core plan includes the full Agent with Plan and Build modes, according to Replit pricing documentation.

Why teams choose Replit: Replit removes local setup completely, which is why it shows up in education and hackathons. Replit Pro also pools credits for up to 15 builders with no per-seat fee, which can make it cheaper than per-seat tools for a small group that builds occasionally.

Replit for companies: Replit code lives in Replit's cloud, so it is not an option for teams that must keep code on their own infrastructure. For startups and internal tooling teams, that trade-off is often acceptable.

Replit limitations: Large monorepos, custom local toolchains and deep debugging are easier in a desktop editor with GitHub Copilot or Tabnine. Replit works best as a place to start projects, not always as the place large teams maintain them.

Replit pricing: Starter is free. Replit announced in February 2026 that Core dropped from $25 to $20 a month (or $204 a year billed annually), and Pro starts at $100 a month with tiered credit options up to $4,000 a month.

For a typical 50-developer team, GitHub Copilot Business is the cheapest per-seat option at $11,400 a year, roughly half the cost of Copilot Enterprise or Devin Desktop Teams. The table below shows the published list prices; Tabnine and Replit price teams differently, so they are noted separately.

Here is the worked math for 50 developers over 12 months at list price. Put simply, a 50-person team pays $11,400 a year for Copilot Business, while the same headcount on Devin Desktop Teams comes to $24,960. Copilot Enterprise works out to $23,400 ($39 x 50 x 12). Devin Desktop Teams is $80 plus $2,000 in seat fees, or $2,080 a month. None of these figures include extra usage, which Copilot bills in AI Credits and Devin Desktop bills at API pricing.

GitHub Copilot Business is the most cost-effective choice for most teams under 50 developers: low per-seat cost, no infrastructure to run and no editor change. Devin Desktop Teams is worth the extra spend if your developers already work agent-first. Tabnine Enterprise makes sense when compliance rules out cloud tools, and the infrastructure cost of a private install should be part of that budget.

If Cursor is also on your shortlist, our Cursor vs GitHub Copilot comparison covers that matchup, and our AI coding tools guide ranks the wider field, including Claude Code.

Three questions settle the choice. First, can your code leave your infrastructure? If not, start with Tabnine. Second, does your team already live in GitHub and a mix of editors? If yes, GitHub Copilot is hard to beat on price and fit. Third, do your developers want agents doing multi-step work in a dedicated editor? If yes, trial Devin Desktop Pro for a month before buying seats.

Does the old Codeium plugin still work in JetBrains? The Windsurf plugin for JetBrains, the successor to the Codeium extension, is still available but is in maintenance mode, and Cascade inside it is being deprecated. Cognition recommends JetBrains users switch to Devin over the Agent Client Protocol.

What replaced Windsurf Cascade? Devin Local replaced Cascade as the main local agent when Windsurf became Devin Desktop on June 2, 2026. Cognition says Devin Local was rewritten in Rust and is up to 30 percent more token efficient, and Cascade stayed available through July 2026.

GitHub Copilot, Devin Desktop, Tabnine and Replit are not interchangeable. Each one is the best answer to a different constraint, and the right pick follows from which constraint your team has.

GitHub Copilot is the sensible default for most developers and teams: the lowest paid prices, the widest IDE support and a coding agent included from the $10 Pro plan. Start with Copilot unless something specific pushes you elsewhere.

Devin Desktop, the product searchers still know as Codeium or Windsurf, earns its place for developers who want an editor built around agents and are comfortable with quota-based usage.

Tabnine is the answer when compliance makes private deployment non-negotiable. Tabnine is the only tool in this comparison that can run fully air-gapped.

Replit fits education, prototyping and non-engineers, where a cloud workspace with no setup gets people to a working app fastest.

Many teams end up using more than one tool, for example Copilot in the main codebase and Replit for quick prototypes. Match each tool to the job it does best.
