BOSUN - Automated Software Maintenance

// the cost of standing still

Tech debt doesn't pause.
Your team shouldn't have to.

Every quarter you delay a migration, the backlog grows. Every agent PR that breaks CI erodes trust. Bosun clears the queue.

Without Bosun

✗ 6-month migration sprints

✗ 47 unpatched CVEs

✗ 3 devs stuck on maintenance

✗ CI breaking every other PR

With Bosun

✓ Migrations in days, not months

✓ CVEs patched automatically

✓ Team ships features, not fixes

✓ Every PR passes CI first time

Framework upgrades take quarters, not days.

Manual migrations fail. Every framework bump — Python 2→3, React class→hooks, Node 16→22 — becomes a multi-sprint project with unclear ownership, incomplete coverage, and regression risk. Meanwhile newer problems keep stacking up.

Bosun's answer AST-level analysis. Automated transforms. PRs that pass CI the first time.

Agent PRs ship fast. But they break CI.

Claude, Cursor, Copilot, and Devin write code at speed. But without validation infrastructure, those PRs flood your review queue full of regressions. Engineers end up fixing agent mistakes instead of shipping features.

Bosun's answer Smart test selection. Auto-fix on failure. PRs your engineers can actually trust.

// the platform

Your automation stack.
End to end.

Bosun isn't a single tool. It's a layered platform: a workflow engine, autonomous agents, and dependency analysis built to turn your most painful maintenance work into a push of a button.

Workflow platform

Compose once.
Run anywhere.

Define multi-step automation pipelines visually: scan, analyze, transform, test, PR. Connect any step to any agent. Your transformation strategy becomes a reproducible, auditable workflow that runs on demand or fires automatically when upstream changes land.

Autonomous agents

Agents that finish
the job.

Bosun's agents plan, execute, validate, and ship autonomously. Each run is fully observable, restartable from any checkpoint, and auditable step by step. They don't just write code; they reason through what needs to happen, fix failures iteratively, and open a PR when everything passes. You review. Done.

Planning for PR creation

I need to prepare a pull request for the hotspot-rs repository. I'll inspect the diff and draft a concise PR that accurately reflects the Rust migration.

Dependency analysis

Know your stack.
Before it breaks.

Bosun maintains a continuously updated graph of your dependencies across all repositories: versions, CVEs, breaking changes, and known migration paths. When something lands upstream that affects you, you know before your CI does, and the fix is already being written.

Open source

Swiftide.
Our RAG foundation.

Before coding agents were everywhere, we were building the infrastructure to power them. Swiftide is our open source Rust library for fast, streaming indexing and retrieval, purpose-built for LLM applications. It's what powers Bosun's codebase intelligence under the hood. We build core infrastructure in the open and contribute it back to the community.

// how it works

Four steps.
No tickets.

Every transformation starts with understanding what you have. Bosun follows a structured process: assess, prepare, execute, validate, so nothing is left to guesswork.

Discover

Assess current state

Bosun maps your entire codebase: dependencies, component patterns, runtime versions, and risk surface. You get a full picture of what you have before anything changes.

Prepare

Build your safety net

Before any transformation begins, Bosun establishes a regression test baseline. It catalogs every affected component and generates missing test coverage, so every change is validated before it ships.

Execute

Run the transformation

Bosun applies transformations across your codebase at scale, updating dependencies, refactoring patterns, and adapting code to the target state. Each change follows documented upgrade paths, not guesswork.

Ship

Validate and deliver

Automated tests run after every transformation. Failures are resolved iteratively. When everything passes, Bosun opens pull requests with full context: what changed, why, and how it was validated. Your engineers approve. Done.

Everything maintenance.
Nothing else.

Dependency upgrades →

Automatic upgrades across npm, pip, Maven, Go modules, and 30+ more. Breaking changes detected, migration paths generated.

Security patching →

CVE monitoring with immediate patch generation. Bosun doesn't just alert you. It fixes the vulnerability and opens the PR before your security team finishes their coffee.

Codebase migrations →

Automated refactoring for framework upgrades, API changes, and language version migrations. Python 2→3. React class→hooks. Node 16→20. We've seen it before.

Test generation →

Every fix Bosun opens comes with tests. On legacy code without coverage? Bosun writes those too, so the refactor is safe before the PR is even reviewed.

CI/CD integration →

Bosun runs inside your existing pipeline. GitHub Actions, GitLab CI, Jenkins, Buildkite. No new toolchain to adopt. No infra to manage.
