Codeium

  • Codeium — Full English Profile (2026-08)

    Codeium launched in 2021 in Mountain View (originally Exafunction; founders Varun Mohan + Douglas Chen). It became the default “free unlimited Tab autocomplete” rival to GitHub Copilot, then shipped the Windsurf Editor​ (Nov 2024, VS Code fork with the Cascade agent), renamed the company Windsurf​ (Apr 2025), saw Google hire away the founding team via a $2.4B licensing deal (Jul 2025), was acquired by Cognition AI (Devin)​ for the remainder (~$250M, Jul 2025), and on June 2, 2026​ the flagship editor was renamed Devin Desktop​ — codeium.com now redirects to devin.ai.

    It belongs to ai-dev-tools under the extension/agentic-IDE route​ (ai-code-app-builder), not Claude Code’s agentic-coding-cli.

    1. One-line positioning

    Codeium (now “Windsurf Plugin, formerly Codeium” on marketplaces + Devin Desktop under Cognition) = the AI coding assistant that won individuals with truly unlimited free Tab completions across 40+ IDEs / 70+ languages, then grew into an agentic IDE via Cascade → Devin Local. In 2026 the paid ladder is Cognition’s Devin: Free $0 / Pro $20 / Max $200 / Teams $80 base + $40 seat / Enterprise custom. Pick the free plugin over Copilot when you want $0 autocomplete in Neovim/Emacs/JetBrains; pick Devin Desktop over Cursor when you already live in the Windsurf/Cognition orbit; Claude Code still owns the terminal CLI lane.

    2. Core features

    • Unlimited Tab completions​ (free, all tiers) — single/multi-line fill-in-the-middle, sub-1s latency, self-hosted SWE-1.x inference stack (~950 tok/s peak)
    • In-editor Chat​ — explain / refactor / debug / generate, repo-aware
    • Semantic Code Search​ — intent-based find across whole repo
    • 40+ IDE plugins​ — VS Code, JetBrains, Neovim, Emacs, Vim, Eclipse, Jupyter, Android Studio, Xcode; broadest coverage in category (Copilot skips Emacs, Cursor is editor-only)
    • Windsurf Editor → Devin Desktop​ — VS Code fork, originally Cascade multi-file agent + terminal + flow state; Cascade retired Jul 1 2026, replaced by Dein Local​ + Agent Command Center multi-agent orchestration
    • SWE-1 model family​ — SWE-1.5 (Oct 2025) → SWE-1.6 (Apr 2026) → SWE-1.7 referenced in Devin Pro; BYOK for GPT-5 / Claude Sonnet / Gemini
    • Enterprise​ — SOC 2 Type II, zero-retention default, VPC/self-hosted/air-gap option, SSO/SAML/OIDC, RBAC, audit logs

    3. Pricing (Cognition Devin ladder, 2026-08)

    Tier Price Key quota
    Free (Devin Free / Codeium plugin free)​ $0​ Unlimited Tab + unlimited inline edits, light agent quota, SWE-1.6 Lite, BYOK allowed, no card
    Pro​ $20/mo​ (was $15 till Mar 2026) Daily+weekly refreshing agent quota, all frontier models, Fast Context, Devin Cloud agents, overage at API price
    Max​ $200/mo​ Power-user agent quotas, everything in Pro
    Teams​ $80/mo base + $40/seat​ (min 2 seats) Shared workspace, central billing, admin analytics, priority support
    Enterprise​ Custom (~$60/seat floor) SSO/RBAC, VPC/air-gap, HIPAA/FedRAMP High, SLA, dedicated CSM
    • CPT: pricing_type = subscription, starting_price = $0, free_tier = "yes; unlimited Tab + inline edits + light agent quota, no expiry", note “Mar-2026 credits→daily/weekly quota; Pro $20 matches Cursor; overage billed at API rates; codeium.com/pricing → devin.ai/pricing”
    • Annual ~17% off on self-serve tiers.

    4. Access Type (v2)

    • access_type: ide-extension, standalone-app, api
    • access_display: 🧩 IDE plugin (marketplace name “Windsurf Plugin (formerly Codeium)”) · 🖥️ Devin Desktop (ex-Windsurf Editor, VS Code fork) · 🔌 Devin API / Enterprise self-host
    • No standalone CLI product (Claude Code owns agentic-coding-cli).

    5. Reviews (split sentiment)

    • Aggregate ~4.2/5 (G2 + Capterra, ~29 reviews), VS Code marketplace “Windsurf Plugin formerly Codeium” ~3.8M installs.
    • Pros: genuinely unlimited free autocomplete; widest IDE coverage; low latency; enterprise zero-retention + air-gap option predates most rivals.
    • Cons: three names in 2 years (Codeium→Windsurf→Devin Desktop)​ fractures docs/roadmap; Cascade killed Jul 2026; free agent quota is thin (3–5 real sessions); Mar-2026 quota switch frustrated heavy users; original team at Google, plugin line in maintenance-mode under Cognition.

    6. Best for

    1. Students / solo devs wanting $0 Copilot-grade Tab​ in any editor (incl. Emacs/Neovim)
    2. Teams with mixed IDEs​ (JetBrains + VS Code + Vim) who refuse to force one editor
    3. Budget-conscious startups — free layer until agent needs justify $20
    4. Compliance shops needing VPC / zero-retention / SOC 2​ without jumping to Tabnine
    5. Legacy Windsurf users migrating cleanly to Devin Desktop (plan preserved)

    7. Not for

    1. Deepest repo-wide agentic refactor → Cursor Composer / Claude Code CLI / Devin Cloud​ beat it
    2. GitHub-native PR/review policy stacks → Copilot Business deeper
    3. Air-gap privacy on Free/Pro → must buy Enterprise
    4. Users allergic to brand churn (2 renames + founder exodus)
    5. CLI-only agentic workflow → Claude Code lane, not Codeium’s
    6. Long-form narrative → Sudowrite, irrelevant here

    8. Competitors

    GitHub Copilot​ (GitHub-native, $10 Pro), Cursor​ (agentic IDE, $20 Pro), Tabnine​ (privacy/air-gap, $9–12 Pro), Sourcegraph Cody​ ($9 Pro), Amazon Q Developer​ (AWS stack, $19 Pro), Replit Ghostwriter​ ($25), Claude Code​ (your 24th card, CLI agentic), Devin Cloud​ (same parent now)
