Control plane
Model choice stays explicit
KCoder Settings > AI Models is the place to configure provider credentials, default models, and validation models.Validation
Evidence before completion
KCoder is built around a validation-first workflow that can review code state, diagnostics, test evidence, and browser evidence when available.Project memory
Durable context for real work
Project memory helps keep source-linked knowledge available across sessions with local search, citations, and health checks.Browser evidence
Inspect what happened
Browser validation traces can include screenshots, console output, network signals, waits, and simple UI interactions as review evidence.Trace history
Review the path taken
Plans, tool summaries, validation results, missing evidence, and artifact references are designed to be inspectable instead of hidden.Developer surface
Built for configurable workflows
MCP, skills, agents, instructions, prompts, hooks, and plugins give advanced users practical control over KCoder workflows.Workflow
Plan, execute, validate, and iterate inside KCoder.
KCoder’s workflow keeps intent, action, evidence, and follow-up work visible so developers can understand how the task moved forward.
Plan
The agent starts with visible intent: files, approach, validation needs, and success criteria.
Execute
Tool calls and edits are tracked as the agent moves through the requested work.
Validate
A validation pass reviews actual code state, diagnostics, test evidence, and browser evidence when relevant.
Iterate
If issues remain, feedback returns to the agent for another pass within user-configured limits.
Models
Designed for BYOK provider configuration.
Use your own provider credentials. Provider keys are user-configured in KCoder Settings > AI Models, where default and validation model choices are managed.
