Blackpaw Studio vs DIY with AI coding tools

Updated October 2026

Short answer

If you can read the code these tools write, build it yourself. Paid plans start at $8 a month. If you can't, or the app is about to hold customer data, get a senior engineer to review it first. I'm Evan Coleman, a solo senior engineer at Blackpaw Studio, and my Production Readiness Audit is $1,500 flat, credited toward any build. The research on whether the tools make experienced developers faster is mixed.^{1, 2, 3}

Who should pick what

Build it yourself if…

You can read the diff. The tools write code, and someone still has to know whether it's right.
It's a prototype, a small feature or a personal project, and a bug costs you little.
You want to learn how it works, or you enjoy building.
You want to keep the cost to a subscription. Cursor Plus is $8 a month, Copilot Pro $10 and Claude Pro $20.^{1, 4, 5}

Pick me if…

You can't review what the tools produce, and the app will hold customer data or payments.
You want a second set of eyes before launch. The audit reviews security, deployment, CI/CD and bugs for $1,500 flat.
You'd rather spend your time on the business. A build is a fixed scope, with MVPs from $15,000.
You want a native iOS app launched to the App Store.

Side by side

Side by side	Blackpaw Studio	Cursor, Claude Code, Copilot, Codex
Cost	Audit $1,500 flat, credited toward any build. MVP from $15,000. Ongoing support from $2,700 a month.	Cursor Plus is $8 a month, Copilot Pro $10, Claude Pro $20 (Claude Code is in Pro and Max) and ChatGPT Plus $20. Each also has tiers from $100 a month. Your own hours aren't in those prices.^{1, 4, 5, 2}
Time to start	One week for the audit. For a build, a written scope and fixed price first, then work starts once the first milestone payment is in.	Today. Cursor, Copilot and ChatGPT list free plans.^{1, 4, 2}
Who does the work	Me. On code you wrote with these tools I review it, fix the critical problems and report the rest.	You, with an AI assistant. METR's 2025 study of 16 experienced open-source developers across 246 issues found they took 19% longer with AI tools. They had expected a 24% speedup, and afterward they still believed they'd been about 20% faster. METR's page says that study is out of date. Its February 2026 update found developers 4–18% faster in late 2025, but both ranges include no change, and METR calls the result "an unreliable signal" because 30–50% of developers skipped tasks they didn't want to do without AI.^{6, 3}
Who's accountable when it breaks	Me. The audit report ranks what's dangerous and I fix the critical items. On a build, I correct defects in the agreed scope for 30 days after delivery.	You. Veracode found AI-generated code introduced risky security flaws in 45% of its tests, across more than 100 models and Java, JavaScript, Python and C#. The report doesn't give a task count.⁷
What you own at the end	Source code, designs and other assets are assigned to you once you've paid in full. For an audit, the fixes go into your own repository.	Your repository and your accounts. Each vendor's terms decide anything beyond that, and I haven't compared them.

Questions

Do AI coding tools make developers faster?

The evidence is mixed. In METR's 2025 study, experienced open-source developers took 19% longer with the tools while expecting to be 24% faster. In its 2026 update, developers returning to the study were 18% faster and new ones 4% faster, but both ranges include no change. METR says the signal is unreliable because 30–50% of developers skipped tasks they didn't want to do without AI.^{6, 3}

Is AI-written code safe to ship?

Not automatically. Veracode found AI-generated code introduced risky security flaws in 45% of its tests, and it doesn't give a task count. GitClear's analysis of 211 million changed lines from 2020 to 2024 found moved or refactored lines fell from 25% in 2021 to under 10% in 2024, and cloned lines rose from 8.3% to 12.3%. It measures how code changed and doesn't count bugs.^{7, 8}

What would you check in something I built myself?

Security, deployment and CI/CD, plus a triage of the bugs. You get a prioritized report in plain English and I apply the critical fixes. It's $1,500 flat, takes one week, and the fee is credited toward any build.
