Cursor vs Void AI in 2026: Composer 2.5 vs a Paused Fork

Last updated May 2026 — refreshed for Cursor 3, Composer 2.5, and Cline 3.85.

Cursor and Void are two AI code editors that share a VS Code lineage and almost nothing else. Cursor has become a $2B+-revenue commercial IDE with its own proprietary Composer models and an aggressive Pro/Pro+/Ultra tier ladder; Void is the MIT-licensed VS Code fork that paused active development in mid-2025 and now sits in maintenance limbo (last src/ commit August 4, 2025). This guide gives you the current state of both, the actual benchmark numbers from May 2026, the real alternatives if Void no longer fits, and a decision tree so you can stop reading and start coding.

What changed by May 2026
Void is still paused. The last binary release was v1.99.30044 on 23 June 2025 and the last meaningful code change to src/ landed August 4, 2025. The homepage still says "Work on Void is currently paused. Some features may be outdated or broken." The MIT-licensed source remains usable; community forks have started to appear.
Cursor 3 shipped in April 2026 as an agent-first redesign of the 2.0 line — parallel agents (up to 8) via git worktrees, native browser tool, BugBot, and Microsoft Teams integration (May 11, 2026).
Composer 2.5 landed on 18 May 2026: 79.8 on SWE-bench Multilingual (up from 73.7), 69.3 on Terminal-Bench 2.0 (up from 61.7), 63.2 on CursorBench. Standard pricing held at $0.50/M input and $2.50/M output tokens — roughly one-tenth of Claude Opus 4.7 per token.
Cline crossed 5M installs. Now shipping at v3.85 (May 25, 2026) with 30+ provider support, the new open-source @cline/sdk agent runtime, and a preview CLI for macOS/Linux.
Cursor pricing is unchanged but more nuanced. Hobby (free), Pro ($20/mo), Pro+ ($60/mo, 3× usage), Ultra ($200/mo, 20× usage), Teams ($40/seat). The June 2025 switch from a 500-request quota to a credit pool still pushes heavy users toward Cline + their own API keys.
The "open-source Cursor alternative" crown has moved. With Void paused, the practical free alternatives are Cline (autonomous agent extension), Aider (terminal + git), and Roo Code (Cline fork with stronger plan orchestration).

TL;DR — which one should you install today?

What is the current state of each tool (May 2026)?

Cursor

• Latest stable: Cursor 3.4 (13 May 2026), the agent-first redesign of the 2.0 line. Composer 2.5 has been the default proprietary model since 18 May 2026.
• Models: Composer / Composer 2 / Composer 2.5 (Cursor proprietary, built on a Kimi K2.5 base from Moonshot AI with continued pretraining and a 4×-scale RL run), plus Claude Opus 4.7, GPT-5.5, Gemini 2.5 Pro, Grok, and the mini tiers via Auto-mode routing.
• Headline benchmarks (Cursor's own publication): Composer 2.5 — 79.8 SWE-bench Multilingual, 63.2 CursorBench, 69.3 Terminal-Bench 2.0. Claude Opus 4.7 is fractionally ahead on SWE-bench Multilingual (80.5) but ~10× more expensive per token.
• Key Cursor 3 features: agent-centric UI, parallel agents (up to 8) with sandboxed worktrees, native browser tool for self-testing, BugBot for PR review (now usage-based billing, not seat fees), Microsoft Teams integration (11 May 2026).
• Distribution: standalone app (macOS / Windows / Linux), cloud agents, JetBrains preview, CLI.

Void

• Status: Active development paused. Homepage explicitly warns "some features may be outdated or broken." The team said they will not actively review issues or PRs but will respond to email about self-maintained forks.
• Latest binary: v1.99.30044 (23 June 2025) on github.com/voideditor/binaries/releases. The last meaningful src/ change landed August 4, 2025. The original voideditor/void repo redirected releases there in mid-2025.
• What still works: Tab autocomplete, Quick Edit (Ctrl+K), Agent / Gather / standard Chat modes, Ollama + DeepSeek + Llama + Qwen + Claude + OpenAI + Gemini connectors (direct API, no Void-owned middleman), MCP support, checkpoint system, VS Code extension compatibility, theme/keymap import.
• What's at risk: security patches in upstream VS Code (Code OSS rebases require maintainer effort), bug fixes for new model APIs, OS-level breakage on macOS/Windows updates.
• License: MIT — anyone can fork and continue.

How do their core philosophies differ?

How do their AI features compare side by side?

Code completion and generation

• Cursor: the proprietary Tab model is widely regarded as the best inline completion in the market; multi-line and cross-file aware. Composer 2.5 handles longer agentic generations with sub-30-second turns for most tasks (Cursor's published spec) and shows substantial improvement on sustained long-horizon work over Composer 2.
• Void: Tab via your chosen model — including local Ollama (Qwen 2.5-Coder, DeepSeek-Coder-V2, Code Llama, etc.). Quality is bounded by the model you bring.

Refactoring and multi-file edits

• Cursor: agent runs in a sandboxed worktree, can plan, edit across many files, run tests, observe failures via the native browser tool, iterate. Multi-agent UI lets you split work (e.g., one agent on backend, one on frontend) and merge.
• Void: Agent mode and Gather (read-only) mode work, but at the v1.99 line — no parallel agent UI, no native browser tool. Capable for single-task refactors when paired with Claude Opus 4.7 or GPT-5.5 keys.

Natural-language commands

• Cursor: excellent. Inline prompts, chat, agent task descriptions, MCP/skills/hooks integration, cloud agents that run while you're offline, and now @Cursor mentions in Microsoft Teams channels.
• Void: chat with file/folder context, custom queries — quality scales with the model. MCP supported.

Debugging and documentation

• Cursor: BugBot reviews PRs (now usage-based billing for Teams and Individual plans, with configurable effort levels — Default, High, or Custom-by-natural-language). Native browser tool means agents see actual runtime failures, not just stack traces.
• Void: diagnostics passthrough from your LLM. No equivalent of BugBot. Documentation generation works through prompts.

How do they compare on AI model integration?

If "I want to swap models without paying anyone a markup" is your priority, Void still wins on architecture — but if "I want today's best agentic loop with the least friction" is your priority, Cursor's tighter integration is hard to beat. Composer 2.5 at one-tenth the price of Opus 4.7 also closes most of the cost-conscious arguments that previously pushed users to BYO-key setups.

What about privacy, data control, and security?

• Cursor: code is sent to Cursor's backend by default. Privacy mode (no code retention) is available on all paid tiers, including Pro at $20/mo. Enterprise adds SCIM, audit logs, SSO, and (as of May 2026) granular admin controls to block providers/models and set soft usage limits with 50/80/100% alerts.
• Void: requests go from your machine to your chosen model with no Void-owned middleman. With Ollama you can stay fully offline. This is the strongest single argument for Void even in its paused state — a regulated team that must keep code on-prem can fork v1.99 today and keep it running.

How much does each cost? (May 2026)

Note on Cursor's June 2025 pricing change: Cursor moved from a fixed 500-request quota to a credit pool sized at the plan's dollar value. For some workflows (premium models, long agent runs) this effectively cut requests at the $20 tier roughly in half, which produced a public CEO apology and a measurable migration to Windsurf and Cline among heavy users. The Pro+ tier was added in part to absorb that complaint. Composer 2.5's lower per-token pricing eases the squeeze, but verify your monthly credit consumption in the dashboard before upgrading.

What do the 2026 benchmarks actually say?

All numbers below are from vendors' own publications or independent leaderboards. Treat agentic-coding benchmarks as directional, not gospel — different harnesses give different results.

Void doesn't publish benchmarks; its performance is whatever the model you plug in scores. A reasonable baseline: Void + Claude Opus 4.7 via your own API key gets you close to a Cursor Pro experience for chat/agent flows, minus the Composer-specific speed advantage, the multi-agent UI, and the 10× cost gap that Composer 2.5 now offers.

How do they feel day to day?

Familiarity and migration

Both editors keep the VS Code chrome. Void will literally import your VS Code settings, themes, and keybindings. Cursor's import is similar but the agent-centric Cursor 3 redesign moves some panels around — expect a 30-minute reorientation.

Customization

• Cursor: some default keybindings (e.g., Cmd+K) are repurposed for AI prompts, which can collide with muscle memory. Settings sync works, but Cursor doesn't ship every VS Code marketplace extension verbatim.
• Void: full VS Code extension marketplace compatibility because it's a closer fork. No proprietary keybinding hijacks.

Day-to-day performance

• Cursor: Tab feels instant; agent runs are bounded by model latency. Composer 2.5's stated improvement on long-horizon tasks matches our subjective experience — fewer mid-run derails on multi-file refactors.
• Void: Tab/agent latency is whatever your local model + hardware can do. A 14B coder model on a 24 GB consumer GPU is good enough for autocomplete; an agent run will be slower than Cursor on a hosted Composer 2.5.

What was removed and what to use instead

The original 2025 version of this post recommended Void as the "actively developed open-source alternative." That framing is no longer accurate. If you can't or won't use Cursor, here is the May 2026 short list:

• Cline — VS Code extension, Apache 2.0 licensed, 5M+ installs, currently shipping at v3.85 (May 25, 2026). Plan/Act modes, MCP, terminal/file/browser tool use, 30+ provider support, preview CLI for macOS/Linux. The closest open-source match to Cursor's agent. Free; you bring your own API key.
• Aider — terminal-native, git-aware, ideal if you live in tmux. Each AI edit is a real git commit you can revert.
• Roo Code — Cline fork with stronger orchestration of multi-step plans.
• Continue.dev — pivoted in mid-2025 from "VS Code AI extension" to a CI-first platform. The IDE extension still exists but the core product is now PR-time code-quality checks defined in version-controlled markdown.
• Void (frozen) — only if your team has the engineering capacity to maintain a paused VS Code fork. The license allows it; the workload is real.

If you're hiring engineers to evaluate or build on top of these tools, Codersera maintains a roster of vetted remote developers with hands-on AI tooling experience.

How do I choose? (decision tree)

1. Is data leaving your machine a hard "no"? Use Void (frozen) or Cline + Ollama with a local coder model. Cursor is out.
2. Do you need the fastest agentic loop available today? Cursor Pro or Pro+ with Composer 2.5.
3. Do you spend $200/mo+ on API calls already? Cursor Ultra or Cline + your own API key, depending on whether you value the integrated UI.
4. Are you on a team that needs SSO, audit logs, central billing? Cursor Teams or Enterprise.
5. Are you cost-sensitive and willing to manage your own setup? Cline + a Claude or GPT API key, or Aider for terminal workflows. (Composer 2.5's per-token pricing now competes here too.)
6. Do you specifically want a VS Code-fork standalone app, not an extension? Void v1.99 still works, but factor in the maintenance risk.

What are the common pitfalls?

• Cursor credit-pool surprises. Long agent runs on premium models burn through Pro's $20 pool faster than you'd expect. Use Auto mode or Composer 2.5 for routine work and reserve Opus 4.7 / GPT-5.5 for hard problems. Track usage daily in the dashboard for the first week.
• Cursor and proprietary VS Code extensions. Some extensions (notably Microsoft-published ones tied to the official VS Code marketplace license) won't run in Cursor. Check before migrating a heavy plugin stack.
• Void won't auto-update. Pinned at v1.99.30044. If you depend on a model API that changed its schema (OpenAI's structured outputs, Anthropic's tool-use shape), you'll need to patch yourself or move to a maintained editor.
• Local model expectations. A 7B model is fine for autocomplete; it is not Cursor Composer 2.5. For serious agentic work locally, plan for 32B-class coder models and matching VRAM, or accept latency.
• Multi-agent isn't a magic multiplier. Cursor 3's parallel agents shine on independent subtasks (frontend vs. backend) but introduce merge conflicts on tightly coupled changes. Treat it as 2–3 useful concurrent agents, not 8.
• Privacy mode is opt-in. On Cursor, "Privacy mode" must be enabled in settings; it isn't the default on free or new accounts. Verify before pasting customer code.

FAQ

Is Void editor dead?

No, but development has been paused since mid-2025 and the team is not merging PRs or shipping new releases. The last meaningful src/ commit was August 4, 2025. The MIT license and existing v1.99.30044 binaries mean it's usable today; long-term, expect the gap with Cursor and Cline to widen unless a community fork picks it up.

Is Cursor Pro worth $20/month vs. free alternatives?

For working developers shipping production code daily, yes — Composer 2.5's speed, 10×-cheaper-than-Opus pricing, and the integrated agent UI typically pay for themselves in a few hours of saved context-switching per month. For hobbyists, students, or anyone with a strong privacy requirement, Cline or Aider with your own API key is the better economics.

What is Cursor 3 and Composer 2.5?

Cursor 3 is the April 2026 redesign of the Cursor 2.0 line — an agent-first workspace with parallel agents via git worktrees, a native browser tool for in-loop testing, BugBot, and Microsoft Teams integration. Composer 2.5 (May 18, 2026) is Cursor's current proprietary coding model, built on a Kimi K2.5 base from Moonshot AI. It scores 79.8 on SWE-bench Multilingual and 69.3 on Terminal-Bench 2.0 — fractionally behind Claude Opus 4.7 on the former, but at roughly one-tenth the per-token cost.

Cursor vs. GitHub Copilot in 2026?

Copilot at $10/mo is competitive on basic autocomplete and integrates more cleanly with GitHub-native workflows. Cursor wins on agent depth, the proprietary Tab and Composer 2.5 models, and multi-file refactors. Many teams now run both: Copilot for the JetBrains/VS Code crowd, Cursor for the agentic work.

Can I self-host Void as an enterprise?

Yes — the MIT license permits it. You'd fork voideditor/void, rebase against upstream Code OSS for security patches, and ship internal builds. Plan for a half-time maintainer at minimum. If you don't have that engineering bandwidth, Cline + a private Anthropic or OpenAI workspace will reach the same compliance posture with less custom plumbing.

What model should I use inside Cursor?

Default to Composer 2.5 or Auto mode for routine work — Composer 2.5 is now the best price/performance default and Auto routes to Cursor's cheapest model that handles the task. For hard refactors, planning, or unfamiliar codebases, switch to Claude Opus 4.7. GPT-5.5 is strong on broad reasoning; pick by your team's tolerance for latency vs. quality.

Does Cursor train on my code?

Per Cursor's privacy policy, code is not used for training when Privacy mode is enabled. Privacy mode is available on every paid tier and is enforced contractually for Teams and Enterprise. On free Hobby accounts, opt-out is still available but verify in settings.

I'm on Void today — how do I migrate?

If you want to stay open-source, install the Cline extension into your existing Void v1.99 (it's still a VS Code fork, the marketplace works) and you'll get most of the agent capability without changing editors. If you're willing to switch IDEs, Cursor will import your VS Code settings/extensions in one wizard. Either move takes under 30 minutes.

We're a team of 8 — Cursor Teams or Cline + shared API keys?

Cursor Teams ($40/seat/mo = $320/mo for 8) gives you SSO, central billing, shared rules, analytics, and (as of May 2026) granular admin controls — usually worth it once admin overhead matters. If you're a smaller informal group and OK managing keys yourself, Cline + a shared Anthropic workspace key is materially cheaper.

Bottom line

Pick Cursor if you want the most polished, fastest, most integrated AI coding experience on the market in May 2026 — and you're OK paying $20–$200/month for it. Composer 2.5's price/performance ratio makes the $20 tier easier to justify than ever.

Pick Void only if (a) you have an absolute privacy requirement and (b) you have the engineering capacity to maintain a paused fork. Otherwise, treat Void as a historically important project whose torch has been passed to Cline, Aider, and Roo Code.

Pick a vetted developer over either if your problem isn't "what tool do I install" but "we need to ship this feature next quarter." Codersera's remote engineering team ships production code with these tools daily.
