## Google Antigravity

Google Antigravity is Google's entry into agentic software development, positioned as a platform rather than a single editor. Instead of asking an assistant to autocomplete a line, Antigravity is designed around agents that take on whole tasks: they read a codebase, produce artifacts such as plans and verification tests, and report back so a human can review the work. The product is distributed across several surfaces so it can fit different workflows — the Antigravity App as a command center for running multiple local agents in parallel, the Antigravity IDE as the fully featured editor with agent manager and artifacts, the Antigravity CLI for keyboard-driven terminal work, extensions for existing editors, and the Antigravity SDK for building custom agents on the same agent harness.

The platform is explicitly aimed at a broad audience: professional developers working in large enterprise codebases, hobbyists vibe-coding on the side, and everyone in between. Google's marketing highlights use cases like frontend and full-stack development, legacy and codebase migrations, technical debt and backlog burndown, automated testing and QA verification, incident triage and root cause analysis, data pipelines and SQL work, developer onboarding and architecture, and enterprise architecture and strategy.

Antigravity connects to Google's Gemini model line, with the site documenting model releases such as Gemini 4 Carbon, Gemini 4 Argon, and Gemini 3.8 Flash, plus agent features like voice mode, custom agents, and a plugin marketplace. It is available for macOS, Windows, Linux, and Googlebook, and Google states it is available at no charge for developers.

**Pricing & Plans:** Free to download and use for individual developers according to Google's own site; organization and enterprise plans are offered separately (pricing on request). Model and quota details can change, so check the official pricing page before committing a team.

- **Multiple agent surfaces:** A desktop app, a full agentic IDE, a terminal-first CLI, editor extensions, and an SDK let you run Antigravity agents wherever you already work.
- **Parallel local agents:** Group conversations into Projects and run several local agents at the same time, across multiple workspaces, rather than one at a time.
- **Artifacts and verification:** Agents produce designed artifacts such as plans and comprehensive verification tests so output can be reviewed, not just accepted.
- **Built on Gemini models:** Runs on Google's Gemini model line, including releases such as Gemini 4 Carbon, Gemini 4 Argon, and Gemini 3.8 Flash.
- **Agent SDK for custom agents:** Use short Python scripts against the Antigravity harness to prototype custom agents, automate engineering tasks, and run evaluations.

**Strengths:** Free for individual developers and available on macOS, Windows, Linux, and Googlebook; Covers many surfaces — app, IDE, CLI, extensions, SDK — so different workflows are supported; Backed by Google and its Gemini models with a steady release cadence; Verification-oriented: artifacts and tests make agent output easier to review

**Limitations:** Tied to Google's Gemini model line rather than being model-agnostic; Enterprise pricing is not published, so costs require contacting sales; Rapid model and feature changes mean quotas and capabilities can shift

## OpnForm

OpnForm is a form-building platform aimed at teams that want modern form UX without the response caps and lock-in typical of commercial survey tools. The editor is drag-and-drop and supports both single-page and multi-step layouts, so a long intake questionnaire can be broken into a conversational flow. Fields can be governed by conditional logic, calculations and answer piping, and forms can be styled with custom themes, brand colours and fonts. AI assistance is available when you want it for drafting questions or fields, but it stays opt-in rather than being forced into the workflow.

What differentiates OpnForm most is its open-source posture. The full codebase is public and auditable, and organisations can choose between the vendor's hosted cloud, an EU-based cloud deployment, or running the software on their own infrastructure. That matters for companies with data-residency rules or internal security reviews. The product also ships team-oriented controls such as shared workspaces, roles and audit history for form and submission activity, along with SSO and SAML for enterprise accounts and 2FA support.

On the automation side, OpnForm connects to the tools teams already use. Submissions can flow to Slack, Discord or Telegram, sync to Google Sheets or Zapier, trigger notifications and routing rules, or be pulled through a documented REST API and webhooks. Payments are handled natively through Stripe, which makes it usable for registration fees and simple product orders. Forms can be distributed by link, embedded on a website or inside Notion, published on a custom domain, or exported as a QR code for offline collection.

**Pricing & Plans:** Freemium. A generous free tier includes unlimited form submissions with no per-response charges, and paid plans add more control, branding removal, team and enterprise features. EU hosting and self-hosting options are available; check the site's pricing page for current tiers.

- **Open-source, self-hostable form builder:** The full codebase is public and auditable, and you can run OpnForm on the vendor cloud, an EU-hosted instance, or your own infrastructure for complete data ownership.
- **AI assistance when you want it:** Optional AI help for building forms and fields, designed to stay out of the way when you would rather write everything yourself.
- **Smart logic and calculations:** Conditional logic, computed fields, answer piping, hidden fields and redirect-on-submit rules let one form adapt to many different respondents.
- **Unlimited submissions without per-response fees:** Collect as many responses as you need even on the free plan, with no hidden quotas or surprise overage charges.
- **Integrations, payments and API access:** Send data to Slack, Discord, Telegram, Google Sheets or Zapier, take payments via Stripe, and automate anything else with webhooks and a REST API.

**Strengths:** Genuinely open-source with a public codebase and self-hosting path; Unlimited submissions on the free tier with no per-response billing; Strong automation coverage through native integrations, webhooks and a REST API; Enterprise-ready controls including SSO, SAML, roles, audit history and EU hosting

**Limitations:** Self-hosting shifts update, backup and security responsibilities onto your own team; The deep feature set, especially logic and integrations, takes time to learn; Some enterprise compliance capabilities are still described as in progress rather than fully certified
