A DIY stack combines your chosen agent framework, models, tools, storage, runtime, and user interface. Construct ships those operating surfaces as one hosted product.

## Methodology

This is an editorial capability comparison using the linked public vendor documentation and Construct's current first-party product scope as of the publication date. It compares documented product models, not hands-on performance or every plan-specific feature.

## Side by side

| Feature | Construct | DIY agent stack |
|---|---|---|
| Time to start | Hosted product | Build and integrate components |
| Execution | Browser, sandbox, files, apps | Your chosen runtimes |
| Memory | Built-in, inspectable, correctable | Design and operate it yourself |
| Channels | Web, Slack, Telegram, Discord slash commands, email | Build each ingress |
| Operations | Managed scheduling and bounded Activity summaries | Own queues, retries, logs, and upgrades |
| Control | Custom MCP, workspace apps, and model BYOK on Pro | Complete architectural control |

## Hosted and integrated

A production DIY stack may need compute isolation, credential storage, channel integrations, and a UI humans can trust, depending on the components and deployment you choose. Construct bundles these operating surfaces so you assign tasks instead of assembling them.

## Still flexible

Bring your own model key on Pro, connect supported applications, or add a custom MCP server. The agent can use browser and sandbox tools when a structured integration is not enough. It can also build a constrained workspace application and add it to the desktop for a recurring internal process.

## What you would otherwise operate

A production agent needs more than a prompt and model API. Depending on the stack, your team may need to operate compute, browser tasks, app connections, schedules, memory, interruptions, and activity records. Frameworks provide many useful primitives; Construct packages the operating layers into one product while retaining browser, terminal, supported model-key, and extension options.

## The maintenance tradeoff

A DIY stack can match a precise security model, deployment environment, or internal platform. It also makes your team responsible for every model change, connector failure, browser timeout, queue, migration, and support surface. Construct is the shorter path when the goal is to operate an AI employee rather than build the infrastructure around one.

## When to choose Construct

- Want production-ready agent infrastructure now
- Need integrations and channels without building them
- Prefer metered SaaS over ops burden

## When to choose a DIY stack

- Full control over every layer is mandatory
- Air-gapped or on-prem only
- You have a platform team to run it
