One engine. Every surface.

The agentic coding IDE that verifies its own work.

NexCoder plans with a visible todo list, edits files with checkpoint-backed revert, asks before running commands, and checks the result. Six chat modes and a terminal CLI - all thin policy profiles over the same agentic core.

Modes
Agent, Ask, Edit, Debug, Review, Scan
Runtime
Local GGUF or hosted endpoint
Safety
Checkpoints + permission gates
nexcoder - agent mode
The NexCoder CLI: typing a task command, then the agent plans, asks permission, runs the tests, and reports the run verified.

See it in action

A full IDE with the agent built in.

Editor, file tree, terminal, and an always-present agent panel that plans, edits, and reports back - watching your active file the whole time.

NexCoder - editor + agent
The NexCoder IDE: file tree, Python editor, and the agent panel showing a plan with progress checkmarks and a files-changed summary.

Six modes, one engine

Every mode is a thin policy profile - system prompt, tool subset, turn budget - over the same v2 agentic core. Read-only modes never even receive mutating tools.

Full access

Agent

The full agentic loop: plans, edits files, runs permitted commands, and verifies the result end to end.

Full access

Edit

Focused file mutation. Direct edits with checkpoint-backed revert per run or per file.

Full access

Debug

Investigates failures systematically, reproduces them, and applies the minimal fix.

Read-only

Ask

Answers questions about your code. Structurally incapable of changing anything - mutating tools are never offered.

Read-only

Review

Code review over files, diffs, or modules with findings you can act on.

Read-only

Scan

Sweeps a project for issues, risks, and structure - a fast way to learn an unfamiliar codebase.

Agent Mesh

One goal, a team of specialists.

For bigger jobs, an orchestrator decomposes your goal into bounded work units and hands them to specialist agents - Explorer, Implementation, Test, and Review - then verifies the combined result. You watch the whole plan unfold, inspect any node, and cancel at any time.

  • Bounded work units keep each agent focused and reviewable.
  • A live timeline and per-node inspector show exactly what happened.
  • One click cancels the run - queued units simply never start.
NexCoder - Agent Mesh
NexCoder Agent Mesh: an orchestrator node branching into Explorer, Implementation, Test, and Review agents, with a live inspector and timeline.

The same agent in your terminal

Everything the IDE agent can do, scriptable from the shell - interactive permission prompts, full-auto mode, mode profiles, skills, and JSONL event streams.

nexcoder --project C:\MyApp "fix the failing test"
nexcoder --auto --project C:\MyApp "build a landing page"
nexcoder --mode review --project C:\MyApp "review the auth module"
nexcoder "/commit group and commit my changes"

The CLI shares sessions, checkpoints, permissions, memory, and skills with the desktop app through the per-project .nexcoder/ directory. Start a task in the IDE, continue it from the terminal - or wire the JSONL event stream into CI.

See the CLI agent ->

Local-first by design

Run fully offline against a local GGUF model server, or point at the hosted NexCoder endpoint - switching is config-only.

Your code stays local

Relevant-code retrieval ranks files and snippets on your machine. Repository content never has to leave it.

Consumer-GPU friendly

The NexCoder MoE coding model (3B active) runs on 32GB RAM plus a consumer GPU by housing the KV cache in system RAM.

Hosted when you want it

Production clients default to the hosted, OpenAI-compatible NexCoder endpoint. No local model required - just an API key in your .env.
