Autonomous API Maintenance
APIs change. Your code keeps working.
Semvane monitors third-party API changes, identifies the code they affect, generates safe migrations, runs your build and tests, and prepares pull requests for review.
Connect GitHub. No credit card required. Developers approve every merge.

Confidence
The maintenance gap
Your software depends on APIs you don't control.
Modern products rely on payment processors, AI providers, commerce platforms, messaging APIs, cloud SDKs and internal platform contracts. When those systems change, maintenance becomes a manual hunt across changelogs, repositories, files, builds and pull requests.

Workflow
How Semvane works
Semvane follows the same careful workflow a senior engineer would expect: observe dependencies, understand impact, prepare changes, verify results, then hand control back to developers.
01
Connect GitHub
Install the Semvane GitHub App and choose exactly which repositories Semvane can access.
02
Discover Dependencies
Semvane scans your repositories and maps the APIs, SDKs and versions your software depends on.
03
Understand Changes
When an API changes, Semvane identifies which repositories, files and code usages are actually affected.
04
Prepare the Migration
Semvane generates targeted changes, runs your configured build and tests, verifies the result, and prepares a GitHub Pull Request.
Observe
Know what your software depends on.
Before Semvane changes anything, it creates a structured map of the external systems your software relies on.

Understand
Know which changes actually matter to your code.
A changelog tells you what changed. Semvane tells you whether it affects your code.

Act
From breaking API change to tested migration.
Semvane prepares targeted patches, then validates the change with build, tests, static analysis and API-specific checks before it is marked ready.

Platform benefits
Everything required for API maintenance, in one control plane.
The public dashboard is for visibility, configuration, history and control. Developers keep reviewing code where they already work.
Security
Built for source code you care about.
Repository access, execution isolation, tenant boundaries, short-lived credentials and audit history are treated as product foundations, not future chores.
GitHub App access
Repository-level permissions
Short-lived credentials
Tenant isolation
Isolated execution
Audit history
Architecture
Control plane clarity. Execution plane isolation.
Semvane separates product decisions from repository execution. Customer code runs only through isolated sandbox orchestration.

Vision
APIs are the first layer.
Semvane is building toward a broader goal: software that maintains itself as the systems around it evolve.
Software that maintains software.
Pricing
Pricing that will grow with the platform.
Final pricing is coming soon. Early plans are organized around evaluation, small teams, multi-repository engineering teams and enterprise controls.
FAQ
Questions engineering teams ask first
What is Semvane?
Semvane is an autonomous software maintenance platform for third-party API changes. It identifies affected code, prepares migrations, runs validation and opens pull requests for your team to review.
Does Semvane modify production directly?
No. Semvane prepares code changes and GitHub Pull Requests for your team to review. Developers approve every merge.
What integrations are supported?
GitHub and Stripe are supported today. OpenAI, Shopify, Twilio and additional providers are rolling out as the catalog grows.
What happens to our source code?
Semvane uses temporary source checkouts in isolated execution environments. No code remains on our infrastructure after a job completes.
Stop manually chasing API changes.
Let Semvane monitor the APIs your software depends on, identify what breaks, and prepare the migration before it becomes another engineering task.
