One-line verdict: Three genuinely different philosophies, not three versions of the same tool. Cursor (now owned by SpaceX/xAI as of August 14, 2026) is the best interactive AI IDE — inline autocomplete, multi-model access, visual diff review. Devin Desktop (formerly Windsurf) is the best free entry point — unlimited Tab completions at $0, with agentic capability layered on top. Claude Code is the best autonomous agent for hard, long-horizon tasks — highest published benchmark accuracy, 1M token context, no inline autocomplete at all. Most experienced developers in 2026 don't pick one; they run a completion-focused tool alongside Claude Code for the tasks that actually need deep reasoning.

The Three Philosophies, in Plain Terms
You pick the model per task — Claude for reasoning, GPT for breadth, Composer for speed. Every change appears as a visual diff you approve. Now backed by SpaceX's compute and Grok's model family, though third-party models remain available as of this writing.
Built around a genuinely usable free tier — unlimited Tab completions at $0 forever. Agentic capability (Devin Local) sits on top for paid users. The budget-conscious entry point into agentic IDEs.
No inline completions at all. You brief a task in the terminal; it plans, executes across files, tests, and iterates with the highest published benchmark accuracy in the category. Built for delegation, not typing assistance.
What Changed With the SpaceX Acquisition Closing
The deal was first announced June 16, 2026 as a pending $60 billion all-stock transaction; it officially closed August 14, 2026, roughly two months later — notably fast for a deal of this size. Cursor's parent company Anysphere now sits inside "SpaceXAI," working alongside Grok Build, Grok Bot, and the Grok API rather than as a standalone acquisition sitting untouched.
What's concretely known as of this writing:
- Cursor's model picker is unchanged — Claude, GPT, and Cursor's own Composer models remain available side by side
- Grok 4.6 (released August 12, 2026) scored 61 on the Artificial Analysis Intelligence Index — roughly matching GPT-5.6 Sol Max, a credible but not dominant frontier result
- No official pricing, feature, or branding changes have been announced beyond the ownership transfer itself
- Cursor's own public messaging frames the move as joining the SpaceXAI team "to help make Grok the world's most useful AI" — language that signals direction without confirming a forced model-exclusivity change
The structural tension worth watching: Anthropic committed roughly $45 billion (about $15 billion/year) to SpaceX compute in May 2026 — meaning one of Cursor's most direct competitors (Claude Code) is now a major customer of Cursor's own parent company, while Cursor continues to offer Claude models inside its editor. That's a stable arrangement while everyone's growing, and a potentially fragile one if incentives shift. Nothing has changed for users yet; this is a "watch, don't react" situation.
Benchmark and Capability Comparison
| Metric | Cursor | Devin Desktop | Claude Code |
|---|---|---|---|
| Published SWE-bench score | None (Composer 2.5: 79.8% SWE-bench Multilingual) | None | 88.6% Verified (Opus 4.8) — category leader |
| Best at simple, targeted edits | ✅ Strong — visual diff, fast iteration | Adequate | Overkill for trivial tasks |
| Best at complex multi-file refactors | Good | Adequate | ✅ Strongest — full-repo context, highest accuracy |
| Token efficiency (complex tasks) | Baseline | Not independently benchmarked | ✅ ~5.5× fewer tokens than Cursor on multi-file work |
| Runs when your laptop is off | Via Background Agents (cloud VMs) | Via cloud agent runs | ✅ Scheduled routines on Anthropic infra |

Pricing: The Real Numbers
| Tier | Cursor | Devin Desktop | Claude Code |
|---|---|---|---|
| Free | Hobby — limited Tab + Agent | Free — unlimited Tab, limited Devin Local | None |
| Entry paid | $20/mo (Pro) | $20/mo (Pro) | $20/mo (Pro, ~45 msgs/5hr window) |
| Power user | $60–$200/mo (Pro+/Ultra) | $200/mo (Max, new tier from July rebrand) | $100–$200/mo (Max 5×/20×) |
| Team | $40/user/mo | $80/mo + $40/seat | ~$125/user/mo (3× Cursor's team price) |
The team-pricing gap is the most consequential number for organizations. A 10-person team costs $400/month on Cursor Teams versus roughly $1,250/month on Claude Code Premium — a real budget decision, not a rounding error. Devin Desktop's team pricing sits between the two.
Who Should Choose Which
Choose Cursor if:
- You want multi-model flexibility (Claude, GPT, Composer) in one subscription
- Inline autocomplete and a visual diff review are core to how you work
- Your team is budget-sensitive at scale ($40/user vs $125/user for Claude Code)
- You want PR review automation (BugBot) and Design Mode for frontend work
Choose Devin Desktop if:
- You want the strongest genuinely-free entry point — unlimited Tab completions at $0 forever
- You're budget-conscious and want to try agentic capability before paying
- You already use Cognition's Devin for cloud-based autonomous tasks and want a consistent product family
Choose Claude Code if:
- You do genuinely hard, long-horizon tasks — framework migrations, deep refactors, unfamiliar codebase exploration
- You want the highest available benchmark accuracy (88.6% SWE-bench) regardless of cost per task
- You work terminal-first and don't rely on inline autocomplete
- You want tasks that keep running when your laptop is closed
The Combination Most Developers Actually Use
- Cursor Pro ($20/mo) or Devin Desktop Free ($0) — handles daily interactive coding, inline completions, and visual-diff agentic edits
- Claude Code Pro ($20/mo) — handles the "brief it and walk away" tasks that would take hours manually
These tools don't compete for the same moment of your workflow — one handles typing velocity, the other handles delegation. Running both costs less than Claude Code Premium's team tier alone and covers a wider range of task types than either tool covers on its own.
FAQ
Is Cursor now a Grok-branded product?
Not currently. SpaceX closed its acquisition of Cursor on August 14, 2026, and Cursor's parent company now sits inside SpaceXAI alongside Grok Build, Grok Bot, and the Grok API — but as of this writing, Cursor's product, pricing, and multi-model access (Claude, GPT, Composer) are unchanged. No rebrand or model-exclusivity change has been officially announced.
Will Cursor drop support for Claude and GPT models now that SpaceX owns it?
No announcement has confirmed this, and doing so would be a meaningful breaking change for users who specifically rely on Claude or GPT for certain tasks — Cursor has marketed model neutrality as a core feature. The more likely near-term path, based on how Cursor has framed the acquisition publicly, is that SpaceXAI's own models (Grok, via the Composer lineage) become an increasingly emphasized default option rather than the only option. Treat this as unconfirmed until Cursor or SpaceXAI states it directly.
Which of these three has the best free tier?
Devin Desktop's free tier is the strongest for genuinely free, indefinite use — unlimited Tab autocomplete with no expiration. Cursor's free (Hobby) tier is more limited — roughly 2,000 completions and 50 slow agent requests per month, functioning more as an extended trial. Claude Code has no free tier at all; it starts at $20/month.
Which tool should a solo developer on a budget choose?
Devin Desktop Free for daily completions, paired with Claude Code Pro ($20/month) only when you hit a task that genuinely needs deep multi-file reasoning — most solo developers don't need Claude Code's capability for every task, so this combination minimizes cost while covering both ends of the workflow.
Which tool is best for a team managing budget carefully?
Cursor Teams at $40/user/month is significantly cheaper than Claude Code Premium at roughly $125/user/month — a 10-person team saves over $800/month choosing Cursor. If your team's work is dominated by complex, high-stakes refactors where Claude Code's accuracy advantage pays for itself, the premium may be justified for a subset of engineers rather than the whole team.
Does the SpaceX acquisition affect Cursor's JetBrains support via ACP?
No indication of this so far. Cursor 3.0's Agent Client Protocol support for JetBrains IDEs, shipped before the acquisition closed, remains part of the product with no announced changes.
