AI-native
delivery
AI in the loop from spec to ship: generation, review, refactors, tests, docs. Faster than agencies built before the AI era, without the brittleness vibe coding leaves behind.
Technical partner for agencies and digital studios
Deliver more client projects without growing your development team.
White-label engineering your clients won't see seams in. We deliver under your brand, on your cadence, with your account manager owning the relationship. No fixed hires, no project quotes, no scope debates.

Services
From brand to backend, one team.
Stacklane covers product engineering, design, motion, and brand work. One subscription, one cadence, one invoice.
Three ways to ship software today. Stacklane is the fourth.
In-house hiring
Months of recruiting, then onboarding, then attrition. By the time the team ships, the market has moved.
We start this week, AI-native, production-grade.
Freelancers & marketplaces
Quality varies. No ownership. They disappear mid-project, and the next one inherits a brittle codebase.
We own delivery, not just tasks.
Vibe-coding studios + legacy agencies
Vibe coders ship demoware that breaks in production. Legacy agencies bill hours and pretend AI doesn't exist.
AI speed, senior judgment, real software.
You focus on growth. We ship real software.
White-label playbook
How the white-label model actually works
Most agencies that 'have engineering' either carry overhead at low utilization or scramble for freelancers under deadline. The white-label subscription is a third option. Here is how we structure it.
01
Sub-contract structure
A clean contractual arrangement that makes the white-label legal-grade, not a wink-wink.
02
Your project codes, your repos
We work inside your project management, your version control, your deployment pipeline. Nothing leaks the seam.
03
Your account manager owns the client
We do not contact the client. Status updates, scope debates, change orders all flow through you.
04
Pause when the pipeline dries up
Variable cost that tracks your client pipeline. No layoff risk, no bench utilization spreadsheet.
05
Engineering quality you can brag about
Senior team, code review, real test coverage. Your clients see your brand; your clients receive our quality.

Daily
shipping
Features land every working day, not at quarter-end. Continuous progress visible in your repo, not in a slide deck. Pause with 7 days notice.
End-to-end
ownership
Accountable for what ships, not what gets coded. Discovery, design, build, deploy, maintain. One subscription, one team that owns the outcome.

Questions & answers
Frequently Asked Questions
01
How fast will I receive results?
We usually start the same day after onboarding. You'll see progress daily and weekly, with features and improvements delivered continuously based on your backlog and priorities.
02
Who will work on my product?
Senior engineers, 8+ years in production, with AI in the loop end-to-end. We use the AI tooling, we own the architecture, and we sign the review on every PR. Stacklane takes full responsibility for engineering delivery.
03
Is there a limit to how many requests I can make?
No, you can submit as many requests as you want.
04
How do you handle larger requests or features?
Large features are broken down into smaller milestones and delivered step by step. You always see progress and can adjust priorities as we go.
05
Can agencies use this as a white-label solution?
Yes. Agencies can work with Stacklane as a technical partner and offer our engineering services under their own brand if desired.
06
What if I only have a single request or small project?
We also offer one-off projects with fixed pricing. If you don't need ongoing development, a one-off project may be a better fit.
07
What if I don't like the result?
We work closely with you and iterate based on feedback. Our goal is to build software that fits your needs, not just deliver code.
08
Are there any requests you don't support?
We focus on software development and product design. We are not a good fit for simple marketing websites, very small design-only tasks or non-software services. If you're unsure, we'll help you determine fit during the discovery call.
09
How do we communicate and request work?
You submit requests through a shared backlog or project board. We communicate through tools like Slack, email, and regular check-ins.
10
How does pricing work?
Stacklane works on a flat monthly subscription: predictable pricing, no hidden fees, no long-term contracts. You can scale up, pause, or cancel at any time.
11
Are there any refunds?
We don't refund time already worked. Pause or cancel any time to avoid future charges; both take effect from the next billing cycle.
