Move beyond AI coding.
Ship with agentic engineering.

Tcoder.ai turns intent into production software. Delegate real work to coding agents that plan, build, test, and open the PR — in your IDE, your terminal, and the cloud.

Agent · fixing #482

Payments randomly double-capture under load. Find it and fix it.

Root cause: no idempotency key on gateway retries. I added key generation, exponential backoff, and 12 regression tests. All green — PR is ready.

Engineering teams ship faster with Tcoder

Agents

Agents turn intent into shipped code

Describe the outcome. Your agent explores the codebase, plans the change, writes the code, runs the tests, and hands you a reviewable diff — so you stay in the decisions, not the keystrokes.

Plans before it types

Every task starts with an explicit plan you can edit, approve, or redirect.

Verifies its own work

Agents run your test suite, linters, and typecheckers before they ever ask for review.

Reviewable by design

Small, well-scoped diffs with rationale on every change. Nothing lands without you.

Cloud agents

Works autonomously. Runs in parallel.

Kick off a fleet of agents in isolated cloud sandboxes. Each one owns a task end-to-end — building features, fixing bugs, upgrading dependencies — while you review results, not progress bars.

Isolated sandboxes

Every run gets its own environment and branch. No stepping on your working tree.

Fan out, then merge

Run ten tasks at once. Tcoder sequences merges and resolves the conflicts.

Everywhere you work

In every tool, at every step

One agent, every surface. Start a task from the IDE, check on it from Slack, land it from the terminal.

Terminal & CLI

Full agent loop in your shell. Script it, pipe it, put it in CI.

IDE

Native app plus extensions for VS Code and JetBrains.

Slack & Teams

Mention @tcoder in a thread and get a PR link back.

GitHub & GitLab

Agents review PRs, respond to comments, and fix CI failures.

Web & Mobile

Launch and review agent runs from any browser or your phone.

MCP & API

Bring your own tools and data sources with open protocols.

❯npm install -g tcoder

Automations

Automate the work you repeat

Turn recurring engineering chores into standing agents. Schedule them, or trigger them from events — a failing build, a new issue, a security advisory.

Scheduled runs

Nightly dependency bumps, weekly dead-code sweeps, morning triage reports.

Event triggers

CI goes red → an agent bisects, fixes, and reruns before you've seen the alert.

Engineers stay for the review queue

Composite feedback from our design partners during the Tcoder 2.0 beta.

"We pointed Tcoder at a six-year-old monolith and it opened 34 mergeable PRs in the first week. The diffs read like a careful senior engineer wrote them."

Linh NguyenVP Engineering · Heliotype

"The parallel cloud runs changed how we plan sprints. We fan out the backlog on Monday and spend the week reviewing instead of grinding."

Marcus OkaforStaff Engineer · Quanta Grid

"Plan mode is the killer feature. I edit the plan, not the code — and the agent verifies everything before I ever see it. Review time dropped by half."

Model intelligence

The best model for every task

Tcoder routes each step to the strongest available model — frontier reasoning for planning, fast models for edits. Or pin exactly what you want.

model — auto-routing

Codebase intelligence

Complete codebase understanding

Tcoder builds a live semantic graph of your repositories — symbols, ownership, history, and runtime traces. Ask anything; get answers with receipts.

Ask in plain language

"Where do we retry webhooks?" answered with linked files and line numbers.

Impact analysis

See every caller, config, and test a change touches — before you make it.

ask — monorepo (12 services)

Enterprise

Built for teams that ship for decades

Security, governance, and control designed with regulated design partners from day one.

Private by default

Zero data retention mode. Your code never trains anyone's model.

SSO & SCIM

SAML, OIDC, and directory sync with role-based access control.

Full audit trail

Every agent action logged, attributable, and exportable.

Deploy anywhere

Cloud, VPC, or fully on-prem — including air-gapped installs.

FAQ

Questions, answered

What makes Tcoder different from an AI autocomplete tool?

Autocomplete predicts your next keystroke. Tcoder agents own outcomes: they plan a change, execute it across files, run your tests, and open a reviewable PR. You operate at the level of intent — agentic engineering — instead of line-by-line generation.

Is my code used to train models?

No. Training on your code is off for all plans, and Enterprise adds zero-data-retention mode where nothing persists after a request completes. On-prem deployments keep everything inside your network.

Can agents really be trusted to change production code?

Agents never push to protected branches. Every task produces a branch and a PR with the plan, the diff, and passing test results attached. You set the guardrails — required approvals, protected paths, and command allowlists — and the audit log records every action.

Which languages and frameworks are supported?

Anything with text source: TypeScript, Python, Go, Rust, Java, C#, C/C++, Ruby, PHP, Swift, Kotlin and more. The semantic graph has deep support for the major web, backend, and mobile frameworks, and MCP lets you plug in custom toolchains.

Can I use my own model or API keys?

Yes. Auto-routing picks the best available model per step, but you can pin any supported provider or bring your own API-compatible endpoint — including self-hosted models for air-gapped environments.
