Arca OS is building a new way to create software: an AI-native application builder powered by ARC Chain and designed to run directly in your browser. Start with a simple idea, then let the autonomous agent analyze your request, create a plan, write the code, and turn it into a working application. Every generated project opens inside an isolated browser-based development environment where you can inspect files, edit the source, run commands, watch the agent’s progress, and preview the result in real time. Arca OS combines AI generation, a complete browser IDE, GitHub integration, secure wallet authentication, persistent projects, and transparent usage-based credits in one focused workspace. No complicated local setup. No jumping between disconnected tools. Just connect your wallet, describe what you want to build, and move from idea to functional software. Build faster. Stay in control. Build beyond imagination. #arc $ARCA

Our vision is simple. Everything useful on Arc should be buildable from Arca OS. Not just landing pages. Real utilities. Real products. Real software that people can open, use, and ship. The mission is to give builders one workspace on Arc: describe the idea, assemble the work, verify it, and put it live. If Arc is the Economic OS, Arca OS is where the applications get made. arcaos.xyz/

Arca OS Runtime V2 is complete - and it was tested not just with unit tests, but in real, isolated Daytona sandboxes. We ran Vite and Next.js fixtures through dependency installation, production builds, dev servers, signed previews, and Chromium render checks. npm, pnpm via Corepack, Yarn Classic via Corepack, and Bun passed. Six failure scenarios were also correctly rejected with clear diagnostics, including failed installs or builds, early server exits, port conflicts, blank pages, and JavaScript errors. We also tested the Studio flow with a disposable project without using anyone’s build credits. Source revisions and existing lockfiles stayed stable, and the test workspace was cleaned up afterward. We’re not claiming Yarn Berry is ready yet: its build still fails on the current Daytona image. $ARCA $Arc

Arca OS is being upgraded to work more like a real engineering system, not just an AI code generator. It will read projects selectively, focusing only on the files relevant to the task instead of rewriting the entire app. Before making changes, Arca OS will show a clear plan: what files will be modified, what will change, and which actions require approval. After every implementation, it will run checks, builds, and previews. If something fails, it reads the actual error and applies a targeted fix only where needed. Work also stays persistent. Progress and results remain available after reopening the tab, and restarts won't erase changes or trigger duplicate builds. Focused changes. Visible execution. Persistent progress. $Arc $ARCA

We’ve completed a major step toward making Arca OS a place to build and run apps, not just generate code. Arca’s AI now works in the same cloud project workspace as the editor: it can change files, install dependencies, run builds, check previews, and show its actual steps and logs in Studio. We’ve also added full-stack cloud releases alongside static publishing, with isolated deployment environments, runtime logs, and rollback. The goal is a continuous workflow: describe an idea, watch the AI build it, open the project yourself, and publish what you’ve made. We’re now validating that entire prompt-to-live-app journey end to end. $ARCA $Arc

We’ve completed the integration between Arca OS’s AI agent and the Daytona cloud workspace used by the project editor. The AI can now edit project files, install dependencies, run builds and previews, and attempt a limited fix when a check finds an error. In Studio, the plan, file changes, commands, and logs come from actual work—not simulated progress. Deleting files requires approval. If a worker stops unexpectedly, checkpoints help preserve saved work and prevent duplicate charges; an unfinished step is never treated as a successful build. The goal is simple: the AI doesn’t just generate code in a chat. It works on the same app you can open, test, and keep building in the editor. A live end-to-end test with a real wallet is the next verification step. $ARCA

We’re happy to announce our integration with @daytonaio . It gives Arca projects isolated, persistent cloud workspaces where you can edit files, run commands in an interactive terminal, and preview your work live. Stop your workspace and come back later without losing your files or starting over. We’re putting our best effort into making Arca more capable and reliable. We’ll keep building, listening, and improving every day. $ARCA $Arc

Production Autopilot is now live in Arca OS. Building an app was never the finish line. Arca OS now handles the path to production: environment configuration, database migrations, deployment, monitoring, rollback, and incident recovery. Every release is checked in preview before it ships and verified again in production. If a critical issue appears, Arca OS can detect it, restore the last stable version, and prepare a targeted fix. From the first prompt to a live product—and through the problems that come after launch—Arca OS is built to keep software running. $Arc $ARCA

We’re now building Production Autopilot for Arca OS. Creating the application is only the beginning. Arca OS is being upgraded to handle the entire journey from a working project to reliable production software. That includes deployment, database migrations, environment configuration, preview verification, production testing, monitoring, automatic rollback, and incident recovery. Before every release, Arca OS will verify the preview, validate the production environment, apply required migrations safely, and confirm that the live application is actually working. If a release introduces a critical failure, it will diagnose the incident, restore the last stable version, and prepare a targeted fix. The goal is simple: describe what you want to ship, and $Arca OS handles everything required to deploy, verify, monitor, recover, and keep it running. From AI app builder to autonomous production infrastructure.

Arca OS just completed its biggest upgrade yet: autonomous engineering teams. A single prompt can now coordinate specialized agents for product planning, interface design, engineering, runtime testing, security, and deployment. They work in parallel inside the same live project, share durable context, review each other’s work, and continue from checkpoints without repeating completed tasks. Each agent owns a focused responsibility, while Arca OS manages dependencies, resolves conflicts, verifies the combined result, and keeps every decision and action visible in real time. You describe the product. Arca OS assembles the team, builds it, tests it, repairs failures, and prepares it to ship. $Arca OS is no longer just an AI app builder. It is becoming an autonomous software company.

What’s next for Arca OS: autonomous engineering teams. Instead of one AI agent handling an entire build step by step, Arca OS will coordinate specialized agents for product planning, interface design, engineering, runtime testing, security, and deployment. They will work in parallel inside the same live project, share durable context, review each other’s work, resolve failures, and continue from checkpoints without repeating completed tasks. You describe the product. Arca OS assembles the team, builds it, verifies it, and prepares it to ship. The AI app builder is becoming an autonomous software company. $ARCA

We’ve completed the next major upgrade for Arca OS: targeted autonomous self-repair. When a project fails, Arca no longer needs to regenerate everything. It traces the root cause, identifies the affected files, plans the smallest safe repair, applies a focused patch, and verifies the real user flow without disturbing what already works. The loop is now: observe → diagnose → select files → plan → patch → validate → test → compare → repair again only if necessary. This makes autonomous builds faster, more precise, less expensive, and far less likely to introduce regressions. Arca is moving beyond “generate and retry” toward real software engineering: understand the problem, change only what is necessary, and prove the fix works. $ARCA #Arc $Argus

The next major upgrade for Arca OS: targeted autonomous self-repair. Instead of regenerating an entire project when something fails, Arca will trace the problem to the responsible file, understand the surrounding code, create the smallest safe patch, and verify that the fix works without breaking existing features. The upgraded loop will look like this: observe the runtime → identify the root cause → select the affected files → plan a minimal repair → apply the patch → run checks → test the real user flow → compare the result → repair again only if necessary. This should make autonomous builds faster, more precise, and significantly cheaper. It also reduces the risk of losing working functionality during a repair. The goal is to move Arca beyond “generate and retry” toward real software engineering: inspect carefully, change only what is necessary, verify the result, and preserve everything that already works. $ARCA #Arc

No day without buyback and burn. Around 10.5% of the $ARCA supply is already gone. This is a commitment. We will keep doing it to support $ARCA. explorer.arc.io/tx/0x69acd34…

We’ve made a major upgrade to Arca OS’s autonomous agent runtime. The agent can now observe, plan, act, verify, and repair real projects inside a WebContainer—not just generate code and hope it works. Runtime reports are stored durably, so if a worker restarts, a replacement worker can resume the same revision without repeating AI generation. Report delivery automatically retries, identical replays are handled safely, and stale or conflicting reports are rejected. Repair attempts remain bounded across restarts, verified candidates can be recovered without duplicate AI billing, and every observation, repair plan, action, verification, and recovery step is recorded through transparent backend events. This brings Arca OS closer to a truly reliable autonomous builder: restart-safe, measurable, recoverable, and accountable. $ARCA $Arc $usdc

Buyback and burned again. Around 9% of the $ARCA supply is now gone. explorer.arc.io/tx/0xa46c63b…

The next major upgrade coming to Arca OS is Auto Model Routing. Instead of asking users to decide which AI model fits every task, Arca will analyze the request and automatically select the best option. OpenAI will handle fast builds, UI iterations, and smaller changes. Claude will take on complex reasoning, debugging, refactoring, and larger codebases. Before the build begins, Arca will explain why a model was selected. Users can still override the recommendation at any time, and the selected model will remain consistent even if the build is interrupted or resumed after a restart. The goal is simple: better results, less guesswork, and a smarter building experience. $ARCA

Arca OS just upgraded its AI building experience. Users can now switch between OpenAI and Claude Sonnet 5 directly inside the building chat. Why it matters: • Choose the best model for each project • Claude for complex reasoning and coding • OpenAI for fast, flexible generation • Switch models during follow-up prompts • Model choice stays consistent after restarts • Large Claude outputs continue automatically More control. More intelligence. Better builds. $ARCA #ARC

Next on the Arca OS roadmap: model selection for AI building. We’re adding a model switcher directly inside the chat, allowing users to choose between OpenAI and Claude before starting a build. One workspace. Multiple AI models. You choose how to build.

Arca OS now supports @Bitbucket integration. Connect your Bitbucket account securely through wallet-bound OAuth, browse public repositories across your workspaces, and import source code directly into the Arca OS browser IDE. How it works: Sign in to Arca OS with your wallet Open Integrations or Import Select Bitbucket and authorize access Choose a public repository Continue building directly in Arca OS Your Bitbucket session stays linked to your wallet, credentials remain server-side, and provider tokens are never exposed to the browser. Build beyond imagination with $Arca OS.

Day 2. The journey is still early. Workspace is live. Burns are happening. Graduation on Argus is done. $ARCA still has a long way to go. arcaos.xyz/
