How it works

From PR to passing tests,
no human in the loop.

01
Index your repo
Neji scans your codebase once - patterns, architecture, mocking style, test conventions.
02
PR opens
A webhook fires. Neji fetches the diff and identifies which lines need coverage.
03
Tests generated
AI generates tests that look like your team wrote them - targeting uncovered lines only.
04
Self-heal
Tests run in an isolated sandbox. If a test fails, Neji reads the error, understands the root cause, and heals it automatically.
05
Pushed to branch
Passing tests committed to your PR branch. Coverage delta posted as a PR comment.
Features

Not a plugin.
A platform.

Neji is built for engineering teams, not individual developers. Every feature is designed to work at org scale.

⚡
PR-native testing
Every pull request triggers automatic test generation. No manual steps, no IDE plugins, no workflow changes for your team.
🔁
Self-healing tests
Generated tests run in an isolated sandbox. When a test fails, Neji reads the error, understands why, and heals it automatically - no human intervention needed.
UNIQUE
🧠
Codebase intelligence
Neji indexes your repo before generating a single test. Framework, mocking style, naming conventions - tests feel native, not generated.
📈
Coverage on autopilot
Set a target. Neji runs nightly, finds the highest-risk uncovered files, and opens clean PRs grouped by module - ready to review and merge.
🏢
Built for teams
Companies, teams, repos, roles. Coverage goals per team. A shared dashboard so engineering leads always know where coverage stands.
ENTERPRISE
🔧
Extensible pipelines
Define your test generation pipeline in YAML. Add custom steps, swap AI models, integrate your own validation logic. A platform, not a black box.
ENTERPRISE
Pricing

Predictable pricing.

Seat-based pricing that scales with your team, not your PR volume.
