SOLO is All You Need

I know you have multiple tabs open.

ChatGPT to write PRDs with, another agent to conduct research, an AI coding tool to execute, and probably another tool to review and test... What should feel like seamless development ends up feeling like managing a team of AI assistants who've never met each other. And you end up repeating everything to each of them.

AI agents are powerful. They're great at solving problems individually. But it still feels fragmented and disconnected from shipping real software.

So we asked a different question: How can we build a solution that truly drives software development?

That’s what led us to build TRAE SOLO—a Context Engineer that doesn’t just assist with code, but thinks, plans, builds, and ships complete features end-to-end, with the right information and tools.

Here's what's new with TRAE SOLO:

• TRAE SOLO mode
  Autonomously handles your entire development workflow from initial requirements to final deployment. You can monitor progress through an integrated view of your editor, browser, terminal, and documentation, while SOLO writes code, fixes bugs, and ships features without human intervention.

• @SOLO Builder
  Built-in Web Developer that transforms concepts into fully functional websites with end-to-end implementation. Handles everything from drafting a PRD to UI design, code generation, and deploying a working website. Built for both professional developers and hobbyist builders.

• Easy Switch between TRAE SOLO mode and IDE mode
  We put granular control in your hands for how you want to co-develop with AI. Just one switch on the top left lets you choose to keep the agent in the chat panel or let it fully take over and work SOLO.

• All-in-one pricing
  SOLO is included in the Pro Plan. No separate subscriptions.

Context Engineering at Its Core

The secret to an effective AI development solution is less about the code you write or the prompt you start with. As tasks grow more complex, providing complete, precise, and structured context is far more important than a magical prompt.

SOLO is designed with context engineering in mind. It starts by understanding your knowledge architecture, helping you think and plan, and then breaking down complex work into logical steps for implementation.

When you say something like “Build a user login page with email authentication,” SOLO responds with a PRD-style project spec, analyzes your current project architecture, executes with rich information and tools, and provides a clear summary of what has been built.

What You Can Do With SOLO

SOLO For Developers:

Context switching kills flow. You spend more time jumping between specs, debugging APIs, and setting up pipelines than actually building.

Then there’s the tech stack challenge. Learning new frameworks takes time. A developer focused on data infrastructure can’t easily switch to building full-stack apps overnight.

SOLO 10x productivity for every developer.

Say you're a backend engineer adding an email notification when users reset their password. Normally, that means digging through your services, wiring up the queue, writing tests, and double-checking everything before pushing a PR.

With SOLO, you just describe the goal:

“Send an email when a user resets their password. Use our queue system. Include IP and device info.”

SOLO finds the right spot in your repo, reuses existing modules, writes the code, adds tests, and submits a clean PR — all in your context. No setup, no context loss, and no hand-holding.

It’s like having a teammate who already knows your codebase and just gets things done.

SOLO For Small Teams

Traditional team structures were built for an era of specialization and siloed responsibilities. Frontend, backend, infra — each role with a tight domain. But in fast-moving teams, that structure often slows things down. You wait on the one person who knows the stack, or pause until someone has bandwidth.

SOLO is a momentum booster for small teams. Take a typical case: a backend engineer needs to build a dashboard with real-time analytics. Instead of spending a week learning React or waiting on the team’s only frontend dev, they ask SOLO:

“Build a responsive dashboard showing user metrics from our existing API.”

SOLO designs the UI, builds the components, wires up state management, connects to the API, and deploys the app — all within the same repo and tech stack, following the team's best practices. The engineer stays in the loop, reviewing progress, giving feedback, and shipping faster. No bottlenecks.

SOLO For Product Managers:

Turning product ideas into real solutions usually means juggling engineers, designers, and analysts — plus endless PRD drafts and sync meetings. By the time something ships, the window to test the idea may have already passed.

SOLO turns PMs into product builders.

You can validate ideas at the speed of thought and turn concepts into MVPs in days rather than months. Let’s say you're working on a social feature and want to see if adding Instagram and LinkedIn links to user profiles increases engagement. Instead of drafting tickets, pinging designers, and waiting on the next sprint, you tell SOLO:

“Add editable social links to the user profile page with icons for Instagram, LinkedIn, and Twitter.”

SOLO updates the frontend UI, connects to your existing user data model, and creates a polished, clickable version of the profile. You get a working prototype in minutes, not weeks.

Now, product managers can create and demo new features without being blocked by sprint cycles. Whether you're validating a growth idea or preparing a user testing session, SOLO gives you the power to build, test, and iterate — all within a unified workspace that combines documentation, code, and browser in one place.

SOLO For Designers

The gap between design and code is where so many good ideas break down. Accessibility, responsiveness, and design system details often get lost in translation during handoff.

SOLO closes that gap and lets designers build without writing code.

With @SOLO Builder, you can turn your ideas into working, interactive prototypes using natural language or visuals. Just describe what you want, or upload a reference — SOLO handles layouts, responsive behavior, and design tokens automatically.

Want to fine-tune a component directly? With SOLO’s Select & Edit feature, you can click on any visual element right in the browser and make changes instantly for text, spacing, layout, colors...you name it. No need to dig through code or wait for implementation. Just select, adjust, and SOLO updates the underlying code for you in real time.

Designers can now test user interactions with real functionality. You can say goodbye to static mockups and bring ideas to life exactly as envisioned.
