For Developers

CoderSage

An autonomous AI coding agent that pairs with you in your terminal and IDE — reading your codebase, planning multi-file changes, running your tests, and shipping clean commits.

The agent loop, where you already work

CoderSage isn't autocomplete — it's a senior engineer that reads the whole codebase, understands the task, and executes it end-to-end.

Plan → edit → run tests → fix → commit. The same loop you'd run yourself, except CoderSage holds the state for you.

Reads your repo, not just open files
Plans before it writes
Edits multiple files in one task
Runs your tests, not just "hello world"
Commits with meaningful messages
Asks before doing anything risky

What CoderSage can do today

Concrete capabilities, not promises about "the future of work."

Feature implementation

Describe a feature, watch it ship — across components, routes, and tests.

Bug fixing

Paste a stack trace or describe the symptom. CoderSage reproduces, root-causes, and patches.

Refactors at scale

Rename, extract, migrate — across hundreds of files, with tests still green at the end.

Test generation

Reads existing test patterns and writes new ones that match your style — not boilerplate.

Code review & PRs

Reviews PRs against your conventions, drafts the description, suggests fixes inline.

Onboarding new repos

Drop into an unfamiliar codebase and ship the first PR by lunch.

Use it where you already work

No new tab. No new context switch. CoderSage installs in two minutes.
