Best Devin Desktop (formerly Windsurf) Alternatives in 2026

**GPT-6.1 Sol landed in Copilot on OpenAI's launch day (2026-09-29, Pro+/Max/Business/Enterprise), the fifth day-one frontier add in eight days, and on 2026-10-02 the four-model retirement slate executed on schedule: Gemini 3.5 Flash, Gemini 3.6 Flash, Kimi K2.7 Code and Claude Opus 4.7 are gone from every Copilot surface.** Same week: HydraFusion's multi-model orchestration reached VS Code 1.140 and the Copilot app (9/30), **computer use** let Copilot CLI and the Copilot app drive desktop applications on macOS and Windows in public preview (10/01), dynamic workflows defined in code arrived for CLI, app and SDK (10/01), the September VS Code roundup added automations, agent merge and Dev Container sessions (10/01), and Copilot code review gained REST/GraphQL request support with Balanced as the default effort level (10/02). Still ahead: the six-model slate on 10/19 and the 10/22 default policy for new features for Business and Enterprise. The 9/22 and 9/28 adds (Opus 5.5, GPT-6 Sol/Luna, Sonnet 5.5) all stand, metered at provider list pricing.

**Cursor launched two bots for the last mile of shipping code on 2026-09-23 (Teams and Enterprise): Rollouts, which attaches a monitor to every pull request and watches the change as it deploys per environment -- verified healthy, regression detected, or inconclusive -- and Security Review, which posts one comment per PR reporting exploitable bugs with severity, attack path and a proposed fix.** Rollouts is the Cursor rebuild of Firetiger's Change Monitors on the Bot Development Kit; it can open a revert PR or hand a regression to a cloud agent but does not merge or roll back on its own. Models: Anthropic's 9/28 Sonnet 5.5 post quotes SpaceXAI's Sualeh Asif on CursorBench 4.0 -- Sonnet 5.5 at 55.5% 'second only to Opus 5.5' (57.8%); Grok 4.7 and its Cursor-only Fast variant arrived 9/21. **Cursor Projects (9/10, beta)** and the 11/12 OpenAI shutoff watch continue.

**DevDay 2026 (2026-09-29) was mostly a Codex release: GPT-6.1 Sol in Codex and the API at $2/$10 per 1M with cached input cut to $0.10, Codex Cloud (reusable cloud environments, tasks that keep running while your laptop sleeps, on Plus and up), a refreshed CLI with voice steering and an /agents view, Code Review in the desktop app with automatic cloud first passes, Codex Security Cloud with Daybreak Blue models and no separate Daybreak application, and the Agents API gaining computer use** -- plus GPT-6 Astra Ultrafast (300 tokens per second in Codex) on Pro 500 and Enterprise, with GPT-6.1 Sol Ultrafast 'coming soon'. GPT-6.1 Sol nearly matches GPT-6 Astra on DeepSWE at one-fifth of the token price and also landed in GitHub Copilot the same day. Still in place: GPT-6 Sol and Luna (9/22), the Agents API public beta (9/10) and the 8/31 retirement of GPT-5.4 from Codex. On 10/01 OpenAI scheduled GPT-5.3-Codex for API removal on 2027-04-01.

Google's agent-first AI IDE -- deploys up to 5 autonomous coding agents in parallel on a VS Code fork. Antigravity 2.0 (I/O 2026) is the runtime substrate for Gemini Spark, and the Antigravity CLI is now the official successor to Gemini CLI, which stopped serving consumer tiers on 2026-06-18

Roblox Studio's agentic AI that plans, builds, and playtests games. Planning Mode (2026-04-16) + Mesh Generation + Procedural Models brings 3D-native creation to 70M+ daily creators

Anthropic's terminal-based coding agent that reads your whole repo and makes real changes -- not just suggestions. **Claude Opus 5.5 became the default Opus model in 2.1.280 (2026-09-22) and Claude Sonnet 5.5 the default Sonnet in 2.1.284 (2026-09-28)**: Opus 5.5 at $4/$20 with $0.20 cache reads and fast mode at $8/$40 for up to 2.5x speed, Sonnet 5.5 at an unchanged $2/$10 with far fewer tokens per task. Both are 1M context. Fable 5.1 (2026-09-01) remains the top model and still defaults to High effort in Claude Code specifically. **Four more releases 9/29-10/02 (2.1.285-2.1.288) added Claude Mods (plugins that modify deeper behaviour) with a built-in 'You should know' side agent, `claude --desktop` to hand a session to the desktop app, an `allowedProviders` managed setting, a WebFetch kill switch, `--max-findings` on /code-review, and continuation from partial responses when the API times out mid-turn.** Also since 9/22: `/doctor prompt-audit`, `deniedModels`, dollar amounts on spend limits and `attribution: false`.

Describe the app you want in plain English and watch it build itself. **New this week: apps built on Lovable can add live voice conversations through GPT Live (2026-10-01, TanStack Start apps, uses credits), Enterprise workspaces can pin AI processing to EU providers (10/01, costs more credits), Business and Enterprise API keys can be IP-allowlisted (10/01), Lovable can rotate a Cloud database password from chat (9/30), and the Lovable MCP server works inside Muse by Meta (9/29).** **Chat with Lovable (2026-09-21)** adds a free daily chat allowance for thinking, asking and planning without changing code, plus voice conversations and a Telegram surface; apps built on Lovable can now call **Claude Opus 5.5 (9/23)** and **GPT-6 Sol and Luna (9/25)** for their own AI features, and the **Lovable API (9/17)** automates workspaces. $500M ARR (June 2026) and ~1M new projects a week

Mistral's dedicated code model -- Codestral 2 (launched 2026-04-08) relicensed under Apache 2.0, removing the commercial-use restrictions of the original. 22B dense, strong FIM (fill-in-middle), available via Mistral API + Hugging Face

**Cognition crossed a one billion dollar run rate on 2026-09-25** -- '$1B in annualized revenue run rate', less than two years after Devin's GA, naming GE Aerospace, Rivian, Rohlik and Exa -- and opened a Sao Paulo hub on 9/22 with Itau (over 75% of its technology teams on Devin, 300,000+ repositories documented, .NET-to-Java migrations 6x faster), Nubank (a multi-million-line monolith migration 'from years to weeks' at over 20x lower cost), Santander, Natura and EBANX as customers. **Devin Fusion (9/11)** -- the lead/sidekick two-model harness measured at 23-46% lower cost per task -- and the 9/15 AWS multi-year agreement stand.

Cloud IDE with an AI agent that builds full apps from prompts. **Free Mode (2026-08-18)**, powered by OpenAI's GPT-5.6 Luna, lets Core and Pro subscribers chat and run everyday tasks without spending credits -- up to 30 hours of chat a month on Core -- and **Intelligent Model Routing (2026-08-26)** now picks the model per task at what Replit measured as 65% lower cost than the old Max Mode. Replit acquired the charting startup Atta on 2026-09-25. Agent 4 (May 2026) added parallel task execution
