Agent Builder by Airtop vs Google Stitch: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Agent Builder by Airtop and Google Stitch — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Agent Builder by Airtop
Airtop
Describe a browser workflow in plain English and Airtop compiles it into a deterministic, self-healing agent that runs on a schedule.
Key features
- Plain-English Agent Building: Describe the automation you want in a chat interface and Agent Builder builds, tests and deploys it without you writing the steps yourself.
- Compiled Deterministic Agents: Automations are compiled into reusable code with an explicit step definition rather than re-reasoned every run, which Airtop reports as up to 100x more efficient than uncompiled LLM agents.
- Self-Healing Runs: When a target page changes and a run breaks, the agent repairs itself instead of requiring the workflow to be rebuilt by hand.
- Login-Gated Automation: A password vault, built-in and custom proxies and CAPTCHA solving let agents sign in to applications like a human, fill forms and download documents where no API exists.
- Scheduled and Triggered Execution: Agents run on schedules or event triggers across APIs, applications and the open web, with concurrency limits set by plan.
- Pre-Built Integrations: Native connections to HubSpot, Google Ads, Google Sheets, Gmail, Slack, Airtable and B2B enrichment data, plus REST, GraphQL, OAuth, API-key and webhook access using credentials held in the Airtop vault.
- Bring-Your-Own-Agent Web Automation: Web automation can be added to agents already running in n8n, Zapier, Make, Claude Code or Codex instead of rebuilding them on Airtop.
- Mark for Marketing: A companion assistant that takes a stated marketing goal, produces a go-to-market plan and handles the agent build, sequencing, workflow logic and data sourcing.
Best for
- Lead Enrichment and Generation: Find and enrich prospects across social platforms and B2B data sources, then keep CRM records current without manual copying and pasting.
- Invoice Reconciliation: Automate reconciliation and statement retrieval in legacy accounting systems that were never built for API-driven automation.
- Google Ads Management: Research, build and publish campaigns, or hand the goal to Mark and let it assemble the agents that run them.
- Competitive Intelligence: Schedule recurring collection of competitor pricing, positioning and product changes into a repeatable report.
- Portal Data Extraction: Log in to a vendor or provider portal on a schedule, extract the current and prior month's figures and file them, as in the OpenAI spend-monitor template.
- CRM Hygiene at Scale: Update records, close data gaps and sync fields across systems that lack a usable integration.
Google Stitch
Google LLC
Generates UI designs for mobile and web from prompts, sketches, or images to speed design ideation and prototyping.
Key features
- Prompt-to-UI Generation: Produces UI screens for mobile and web from natural-language prompts, sketches, or images to accelerate ideation and mockup creation.
- Sketch and Image Import: Accepts user sketches or images as input and converts them into UI layouts and visual designs to jumpstart the design process.
- Gemini CLI Extension: Provides a Gemini CLI extension enabling natural-language interaction with a Stitch MCP server for generating UIs and managing requests from the terminal.
- MCP Server & Proxy Tooling: Offers an MCP (Managed Control Plane) workflow and proxy utilities to host a Stitch MCP server, route requests, and facilitate local development/testing.
- GCP Integration & Authentication: Integrates with Google Cloud tooling (gcloud) for authentication, Application Default Credentials, project selection, and IAM role setup required to enable the Stitch API.
- CLI-based Setup & Diagnostics: Includes command-line installers and setup commands (e.g., npx @_davideast/stitch-mcp init) that automate installation, enable APIs, configure credentials, and diagnose setup issues.
- Generates UI designs for mobile and web from prompts, sketches, or images
- Hosted Stitch web application for interactive design ideation
- Stitch MCP API for programmatic access and server integration
- Gemini CLI extension to interact with Stitch via natural language commands
- MCP proxy server capability for local/dev proxying of Stitch MCP
- CLI-driven setup and provisioning (npx init, gemini extensions install)
- Google Cloud authentication support (gcloud auth, Application Default Credentials)
- IAM-based access control requirements and project-level service enablement
Best for
- Rapid Design Ideation: Quickly generate multiple UI concepts from a brief or sketch to explore interface directions during early-stage product design.
- Sketch-to-Prototypes: Convert hand-drawn sketches or screenshots into digital UI screens that designers can refine and iterate on.
- Developer Handoff Automation: Produce consistent UI outputs that designers can export or hand off to developers along with configuration for Stitch MCP to streamline implementation.
- CLI-driven Design Workflows: Integrate UI generation into terminal-driven workflows using the Gemini CLI extension for teams that prefer code/CLI environments.
- Enterprise Self-hosting & Control: Deploy and run a Stitch MCP server with GCP integration and IAM controls to maintain access governance and combine Stitch with internal toolchains.
- Local Development & Testing: Use the MCP proxy and diagnostic commands to test Stitch-generated UIs and API interactions in local or staging environments before production rollout.
- Rapid design ideation and exploration of mobile/web UI concepts
- Convert sketches or screenshots into polished UI screens for prototyping
- Automated UI generation in developer workflows via CLI or API
- Integrating AI-driven UI generation into a Google Cloud-based toolchain
- Local development and testing using an MCP proxy server
- CI/CD automation to generate or refresh design assets programmatically
