The platform that ships software, not snippets.
StackWeavers turns your vision into running software, deployed to your own cloud, with the quality of a team that ships for a living. Agents do the work under a human product owner who signs off on the calls that matter. Agentic delivery, human-owned. Not a black-box swarm.
Vision intake, backlog refinement, vertical-slice execution, six automated quality gates, deploy to your cloud, and observability. The whole path, in one platform.
What makes it different.
01
Human-owned, not autonomous.
Agents do the work; a human product owner locks scope and signs off.
02
Vertical, not horizontal.
One feature done end to end before the next starts.
03
Quality gates, not vibes.
Six automated checks before any code merges.
04
No lock-in. Ever.
Your cloud, your code, no training. Privacy, ownership, portability.
What the platform handles.
- Architecture, with a documented pattern per slice
- Database schemas and migrations
- Backend APIs, with contract tests
- Frontend, with component coverage
- Tests (unit, integration, e2e)
- CI/CD
- Deploy to your cloud account (AWS, GCP, Azure). You hold the keys.
- Observability and logs
- Security defaults (TLS, AES-256 at rest)
- Backlog refinement and scope lock (with included product owner on Team and Enterprise)
- Existing-codebase ingestion (Team plan and above)
Two ways you bring your own keys.
StackWeavers is BYO at two independent levels. One is the cloud account where your code actually runs. The other is the LLM provider that powers the agents. You can mix them however you want.
cloud account
Always yours. Every paid plan.
The platform deploys into your own AWS, GCP, or Azure account on Pro, Team, and Enterprise. You hold the cloud keys. We never run your production code on our infrastructure, and we never see your production secrets.
- AWS via your IAM role and VPC.
- GCP via your service account and project.
- Azure via your subscription and VNet.
- VPC and on-prem deploy on Enterprise.
LLM provider
Your choice. Managed or BYOK.
On the managed track, we absorb model spend in your Capacity Unit bundle and route across providers. On the BYOK track, you bring your own model keys and pay your provider directly. Flat platform fee, no CU cap, no per-token markup.
- Anthropic, OpenAI, Google, Mistral direct keys.
- Azure OpenAI, AWS Bedrock, Google Vertex.
- Existing prepaid commits and negotiated rates apply.
- Switch tracks at any renewal.
Specialized Agents
Hire a Development, Architect, or Lead Reviewer agent on demand.
Scoped to one discipline. Billed in Capacity Units per delivered unit. Pair any of the six roles with a human reviewer.
Built to keep, not to throw away.
The dirty secret of fast AI code is that a lot of it gets ripped out. Independent analysis of 211 million lines of changes found duplicated code blocks roughly quadrupled through 2024, the first year copy/paste outpaced reused code. Code churn (work rewritten within two weeks) climbed while refactoring collapsed. And a 2025 security audit across more than 100 models found roughly 45% of AI-generated code introduced a vulnerability. Teams are now paying to clean up what the last wave of AI tools shipped. "Rescue engineering" became a job.
StackWeavers is built against that pattern. The agents work from your real schema, types, and dependencies, check for existing code before writing more, and pass six quality gates before anything merges. The output is production-grade, documented, and conventional. Code you keep and extend, not slop you throw out in a year. It's the whole reason the platform exists.
~4x
growth in duplicated code blocks through 2024 across AI-assisted codebases.
7.9%
of new code rewritten within two weeks, up from 5.5% in 2020.
~45%
of AI-generated code introduced a security vulnerability in 2025 testing.

Failure modes we engineered around.
AI coding tools fail in a small set of predictable ways. Each one has a counter:
Lost in the middle.
Long contexts make agents forget the spec. We chunk, summarize, and re-anchor every slice.
The dumb zone.
Agents loop on a problem they can't solve. We detect, escalate, and reset.
Horizontal sprawl.
Wide surface, nothing shippable. We build vertical slices, end to end.
Runaway cost.
Open-ended runs burn cash. We cap, meter, and surface every unit in real time.
Hallucinated APIs.
Code calls things that don't exist. We ground in your real schema, your real types, your real deps.
Goal drift.
Scope creeps mid-execution. The product owner locks scope before agents start.
Compounding errors.
A bug in slice three cascades through four to ten. Quality gates fail closed.
Integrations roadmap.
StackWeavers is pre-launch. These are the integrations we're shipping for launch. None of them are running with a paying customer yet, so they are all marked Planned. We flip an integration to Beta the first time a design partner connects it, and to Live only after a paying customer has run it in production for 30 days.
