StackWeavers

Pre-launch · Talking to first partners

From vision to production software you own.

Agentic delivery, human-owned. Not a black-box swarm.

StackWeavers builds your product as complete vertical slices, ships it to your own cloud, and leaves you owning the code. AI agents do the work under a human product owner who locks scope and signs off. For founders without a team and teams who want one that scales.

human product owner · ships to your cloud · you own the code · no training on it

Two ways in. Most of our customers come through the first.

founders without a team

I have a vision. Build my product.

You don't need engineers or tickets. A human product owner turns your vision into a backlog, agents build it as production-grade software, and it ships to your own cloud. You own the code. Not a throwaway prototype.

Plus: we help you secure cloud credits from AWS, GCP, Azure, Vercel, and the major model providers, and route you to incubator and accelerator programs where you fit.

engineering leaders

I have a team. Amplify it.

Connect your repo and Jira. Agents follow your conventions, deliver pull requests into your branch flow, and pass six quality gates before merge. A human reviewer signs off on the high-stakes calls.

design partner program

We're looking for our first partners.

Early access, named-partner pricing, and a direct line to the team building StackWeavers. We publish your story here once you ship. We trade discount for honest feedback and the right to share what we learned.

what we ship today

  • Vertical-slice execution. Database, API, UI, tests, deploy.
  • Six automated quality gates before every merge.
  • Glass-box dashboards from vision to deploy.
  • BYOK and customer-cloud deploy. No production access for us.
  • No training on your code. No fine-tuning. Zero retention with providers.

Live data. Not a roadmap.

section/01 · vertical

One feature shipped beats five features half-built.

Most AI tools sprawl horizontally. A button here, a route there. Three sprints in, you have thirty half-features and nothing in production. StackWeavers finishes one feature end to end before the next one starts.

Every deliverable is a vertical slice through your stack. Database schema, API endpoints, frontend UI, tests, and deploy. All shipped together. Six automated quality gates run before any code merges: architecture, code review, test coverage, security scan, performance budget, API contract.

No exceptions. No "we'll add tests later." No four-month rewrite to make the AI code production-ready.

section/02 · visibility

A glass box, not a black box.

Every decision the agents make is visible in real time. Every cost line item. Every quality-gate result. Every pull request. You stay in control by default, not as an upgrade.

Real-time tracking

From vision document to deploy log. Every step has a timestamp, an agent owner, and a cost.

Vision-to-deploy lineage

Click any shipped feature. Trace it back to the exact line in the vision document that asked for it.

Human checkpoints

Scope is locked per deliverable. A human signs off where it matters, the platform automates the rest.

operating principle

"Neither agents nor developers should ship technical debt. The code is high-quality and free of duplicates. Agents and developers work alongside each other as one team."
The standard we hold every commit to.

section/03 · deploy

Two ways to deploy. One commitment.

Bring your own keys and run the agents inside your cloud, or hand us the runtime and we'll manage it. Either way you get sovereign AI by default: no training on your code, no production access for us, and you can walk away with your codebase whenever you want.

section/04 · pricing

A fraction of a team. Pick the team.

A 5-person US team costs $40K to $100K a month. A hybrid US-lead-plus-offshore team is $25K to $50K. An all-India or all-LATAM team is $12K to $45K. The Team plan plus typical usage stays at $2K to $4K. We compare against all four because hybrid onshore-plus-offshore is how most companies actually staff in 2026.

why we built this

Built for the team that maintains what gets shipped.

Most AI coding tools are built for the demo. The thirty-second screencast. The one-shot prompt. The vibe-coded prototype that looks great on stage and falls apart the day it has to take real traffic.

StackWeavers is built for the day after the demo. Production-grade vertical slices. Six automated quality gates before any code merges. A codebase the next developer or the next agent can pick up without a translator. Privacy, ownership, and portability as defaults instead of upsells.

We took the day-two cost of AI-written code seriously. That's the entire thesis.

Frequently asked

Does StackWeavers skip code review?
No. Code review is essential and we don't take it away. Six automated quality gates handle the noise (formatting, contract drift, coverage gaps, performance regressions) so your reviewers can focus on architecture and intent. Every pull request still goes through your team's normal review process.
How does feature versioning work?
Every vertical slice ships with a semver. The platform applies major, minor, or patch bumps based on the shape of the change, with a human in the loop on the bumps that matter. Click any shipped feature to see its full lineage: the original vision line, every diff since, who approved each version. Fork an experiment branch. Roll back in one click.
How does the cost compare to a hybrid or offshore engineering team?
A 5-person US team runs $40K to $100K per month. A hybrid US-lead plus offshore (India or LATAM) team is $25K to $50K. An all-India team is $12K to $25K. An all-LATAM team is $20K to $45K. The Team plan plus typical usage stays at $2K to $4K. That works out to between 4% and 25% of whichever team you'd hire instead.
Do you train models on our code?
No. Never. On any plan, including Free. No fine-tuning on customer data, and zero retention with the model providers we use.
Where does our code live?
In your Git, your cloud, your VPC. The platform deploys into your accounts, not ours. You hold every key.
Can we keep using our existing Jira or Linear?
Yes. Jira and Linear are on the launch integration roadmap. Your tickets stay the source of truth. The platform reads sprints, ships against them, and writes status back. See the full integrations roadmap at /product/integrations.
What happens if we outgrow StackWeavers?
The code is documented and conventional. Hand it to any engineer or any other agentic platform. It will keep working. That's the portability commitment.
Is there a free tier?
Yes. 1 project, 100 Capacity Units per month, full no-training guarantee, no card required. Start at /signup.
