Replit, Cursor and Windsurf are often listed together as AI coding tools, but they solve different problems. Replit centres on an Agent that builds and hosts apps in the browser. Cursor and Windsurf are code editors with AI built in. Over 2026 all three changed their pricing, and two of them changed owners or names, so older comparison articles may no longer be accurate.
This is a decision framework, not a ranking. We set out the questions that matter when you choose between these tools, then fill in what the vendors document about plans, usage limits, ownership and privacy. Where we could only find a figure on a third-party page, we say so.
How we researched this: we did not run hands-on tests for this article. It is based on the vendor’s own documentation and public sources, checked on 11 November 2026. Features and prices change, so confirm details on the vendor’s site before you buy.
Key takeaways
- Replit prices AI use by effort: the Agent bundles finished work into a checkpoint, and simple fixes cost less than complex builds, according to Replit’s documentation.
- Cursor now lists Free, Plus, Premium, Super and Ultra plans with weekly usage pools, and was reported as acquired by SpaceX on 14 August 2026.
- Windsurf replaced credits with daily and weekly usage quotas on 19 March 2026, and a third-party source says the editor is now sold as Devin Desktop.
- Third-party model access is billed differently on each tool, so compare the cost of your usual workload rather than headline monthly prices.
- Run the same small task in each tool and track time, cost and the number of corrections you had to make.
Why compare these three
The three tools share a promise, which is that you describe what you want in plain language and an AI model writes the code. Beyond that they differ in shape. Replit is a hosted development environment where the Agent can create an app, and the platform can also publish it. Cursor and Windsurf are editors you install on your computer, where an AI assistant works on your existing project files.
That difference matters more than any feature list. A non-developer who wants a first working app may care about hosting and a simple interface. A professional developer with a large codebase may care about model choice, usage allowances and how code is handled. Start with how to choose an AI tool if you have not yet written down your use case.
Quick overview
| Point | Replit | Cursor | Windsurf |
|---|---|---|---|
| Shape of the product | Browser-based environment with an Agent and hosting for apps, per its docs | AI code editor; plans sold with Grok access after the SpaceX acquisition, per its pricing page | AI code editor; Cognition published its pricing update |
| How usage is limited | Credits plus effort-based Agent pricing | Weekly usage pool; extra use billed from prepaid credit | Daily and weekly quotas; extra usage at API pricing |
| Free option | Starter plan | Free plan with limited Agent and Chat requests | Free plan with light agent quota |
| Entry paid plan (as listed) | Core: $20 in monthly credits | Plus: $8 a month | Pro: $20 a month |
| Top individual plan (as listed) | Pro: $100 a month | Ultra: $200 a month | Max: $200 a month |
| Team plan (as listed) | Pro offers more seats; Teams not covered in our sources | Teams: from $30 per user a month | Teams: $40 per seat a month |
All prices above are as listed on the vendors’ pages on the date we checked, 11 November 2026, and are subject to change.
Criteria that matter
- Where you want to work. Browser with hosting, or a desktop editor on your own project.
- Who owns and controls the product. Ownership changes can alter pricing, models and terms.
- How usage is metered. Credits, pools, quotas or per-effort charges behave very differently under heavy use.
- Access to outside models. Whether you can use models from other labs and how they are billed.
- Team and data controls. Privacy modes, retention, admin features.
- Predictability of cost. Budgets, alerts, hard caps and confirmations.
Ownership and naming changes
This is the part most likely to catch readers out, because the products you remember from early 2026 may not match what is sold today.
Cursor
Business Today reported, in an article dated 14 August 2026, that SpaceX bought Cursor for $60 billion and that the acquisition took effect that day, about two months after SpaceX formally announced the agreement. Cursor’s own pricing page now shows plans that include access to Grok products: it lists Cursor alongside Grok Chat, Voice and a Grok API on the Plus plan, and says the allowance is shared across Cursor and Grok. A third-party blog dated 26 October 2026 adds that billing moved from cursor.com to grok.com and that the bundle is called The X Subscription. We could not confirm those extra details on a primary source, so treat them as unverified and check where you would be billed.
Windsurf
Windsurf’s pricing update of 18 March 2026 was published on the Devin site, run by Cognition. A third-party pricing article checked on 28 October 2026 says Cognition sells the editor as Devin Desktop and that windsurf.com/pricing redirects to devin.ai. We could not open Windsurf’s own pricing page in this research, so we cannot confirm the new name from the vendor. If you search for “Windsurf” and find different branding, that is likely why.
Replit
We did not find a change of ownership for Replit in our sources. Its main change in the documentation we read is the move to effort-based Agent pricing and credits.
Usage limits and billing
Replit
Replit’s AI billing page says pricing is usage-based. The Agent bundles completed work on a request into a single checkpoint, so simple fixes cost less than complex builds. Core and Pro users get a Free Mode allowance for everyday Agent work within limits, while Starter has a daily cap. Plan Mode can incur charges even when it does not change code. Replit says it asks for confirmation before a paid action starts, and you can set alerts, budgets and hard caps in billing settings. Third-party AI services such as Claude, ChatGPT and Gemini are billed at the provider’s public API rate and deducted from your credits. On Pro, credits roll over for two months.
Cursor
Cursor’s pricing documentation says paid plans share a weekly pool for Cursor models across Agent, CLI, Cloud Agents and Grok apps. The pool refreshes weekly, and different models draw from it at different rates. Past the pool, usage is billed from prepaid credit at per-model rates. Premium and above can use third-party models at API list price from prepaid credit, with no included allowance, while Free and Plus cannot use them. Teams and Enterprise carry an additional $0.25 per million token rate on eligible third-party requests.
Windsurf
Cognition’s post says the old credit system was replaced on 19 March 2026 with usage quotas that refresh daily and weekly. Paid plans can buy extra usage beyond their included quota at API pricing. The post gives estimated messages per day for Pro and Teams, for example 7 to 27 for the top model tier and 47 to 190 for lightweight models, with a weekly limit too, and larger ranges on Max. These are estimates, not guarantees.
| Billing point | Replit | Cursor | Windsurf |
|---|---|---|---|
| Main limit | Credits and effort-based checkpoints | Weekly pool | Daily and weekly quotas |
| Going over | Paid actions confirmed first; budgets and caps available | Prepaid credit at per-model rates | Extra usage at API pricing on paid plans |
| Outside models | Billed at provider API rate from credits | Premium and above, at API list price | Included in model tiers, extra at API pricing |
| Reset cycle | Free Mode allowances reset every five hours on Core and Pro, with weekly limits | Weekly | Daily and weekly |
Plan prices
Checked on 11 November 2026. See how to read an AI tool’s pricing page for how to interpret allowances. Confirm all figures on the vendor pages.
| Plan tier | Replit | Cursor | Windsurf |
|---|---|---|---|
| Free | Starter: daily Agent allowance, limited cloud credits, one published app | Free: limited Agent and Chat requests | Free: light agent quota, unlimited inline edits and Tab completions |
| Low paid | Core: $20 monthly credits; $204 a year if billed annually (monthly price not stated on the page we read) | Plus: $8 a month, Cursor and Grok models only | Pro: $20 a month |
| Mid paid | Pro: $100 a month | Premium: $30 a month (4x Plus usage); Super: $100 a month (15x) | Not listed in our sources |
| High paid | Not listed beyond Pro | Ultra: $200 a month (50x) | Max: $200 a month |
| Team | Pro: up to 15 builders | Teams: $30, $100 or $200 per seat a month | Teams: $40 per seat a month |
A third-party source also reports an $80 minimum per Windsurf team and annual Cursor prices of $80, $300, $1,000 and $2,000 for Plus, Premium, Super and Ultra. Cursor’s documentation page lists those annual figures. For Windsurf, the minimum comes only from a third party.
Privacy and data
Each tool sends your code to an AI model, so ask where it goes and what is kept. Our guide on protecting company data when using AI tools gives a checklist.
- Replit: some features use services such as Claude, ChatGPT and Gemini. The billing page we read does not describe retention, so check Replit’s privacy and terms pages.
- Cursor: the documentation we read is thin. It lists team-wide privacy mode enforcement and custom Chat data retention for Teams, says models are hosted by the model provider, a trusted partner or Cursor, and links to a sub-processor list. Regional data residency adds a 10 percent uplift on eligible models. With the ownership change, check which entity is the data controller in your contract.
- Windsurf: Cognition lists automated zero data retention on the Teams plan. We found nothing in our sources on individual-plan retention.
Who each suits
Replit may suit you if
- You want to build and publish a small app without setting up servers.
- You like spend controls such as budgets, alerts and confirmations.
Cursor may suit you if
- You work in a desktop editor on an existing project.
- You are comfortable with a weekly usage pool and, if needed, prepaid credit for other labs’ models.
Windsurf may suit you if
- You want a fixed monthly price with daily and weekly quotas and the option to pay for overage.
- You are happy to follow Cognition’s product naming changes.
Think twice if
- You need predictable monthly costs and your usage is heavy, since all three vary with usage.
- Your company has rules about code leaving your network.
- You depend on a single model vendor that a plan does not include.
How to run your own test
Use the method from how to compare AI tools side by side fairly.
- Choose three real tasks: a small bug fix, a new feature in an existing project, and a throwaway prototype.
- Run each task in each tool using the same wording and, where possible, a comparable model.
- Record elapsed time, usage or credits consumed, and how many follow-up prompts you needed.
- Review every change before you accept it, and run your tests. AI-written code can be wrong, as our guide to checking AI output explains.
- Repeat across a normal working week to see whether you hit limits.
Decision checklist
- Do I want a hosted builder or an editor on my machine?
- Do I know who owns the product and who bills me?
- Do I understand the unit of usage: checkpoint, pool or quota?
- What happens when I hit the limit: stop, wait or pay more?
- Can I use the models I need on the plan I want?
- Are there team privacy controls and retention commitments in writing?
- Have I tested all three on a real task?
Frequently asked questions
Which is cheapest?
The headline monthly prices differ, but real cost depends on how much you use the AI. Run the same tasks on each tool and compare consumption.
Is Cursor still independent?
Business Today reported on 14 August 2026 that SpaceX completed its acquisition of Cursor. Check Cursor’s current terms for who provides the service.
Is Windsurf now Devin?
A third-party article says the editor is sold as Devin Desktop, but we could not confirm this on a Windsurf page. Cognition’s own March 2026 pricing post refers to Windsurf for the editor and plans.
Can I use Claude or GPT models?
Replit says third-party models are billed at provider API rates from credits. Cursor lists third-party models on Premium and above at API list price. Windsurf lists model tiers that include such models. Check the current model list.
Do these tools train on my code?
Our sources did not state this for Replit, Cursor or Windsurf individual plans, so we could not confirm it. Read each vendor’s privacy terms.
Which is best for a beginner?
Based only on documentation, a hosted environment such as Replit reduces setup, while editors assume you already have a project. Your own test is more reliable.
Conclusion
Replit, Cursor and Windsurf differ in shape, ownership and billing. Replit is the hosted option with effort-based pricing. Cursor is an editor with weekly pools and a new corporate parent. Windsurf is an editor with daily and weekly quotas and uncertain branding. The best choice depends on where you work, how heavily you use AI and how your organisation treats code.
