## EmailWebhook

EmailWebhook is a developer platform that converts Gmail and Outlook activity into structured webhook events. Rather than dealing with historyId tracking, MIME parsing and provider-specific notification formats, teams register a webhook URL and receive clean JSON payloads describing exactly what happened in a mailbox. The service handles the plumbing: watching mailboxes, normalizing messages, refreshing OAuth tokens and retrying deliveries.

The event model is intentionally granular. Developers can subscribe to inbox additions, reads, unread changes, sends, drafts, labels, spam, trash and deletion events, or use catch-all deletion handling. This makes it straightforward to build features like invoice parsing, support ticketing, contract workflows and rapid lead capture without writing provider-specific code.

Beyond inbound events, EmailWebhook offers a unified REST API for sending messages, listing mailboxes, managing labels and migrating users between Gmail and Outlook. Security features include TLS 1.3 in transit, AES-256 at rest, OAuth 2.0 without password storage, audit logging and hosting on Google Cloud Platform, with SOC 2, HIPAA and GDPR compliance noted as pending.

**Pricing & Plans:** EmailWebhook uses usage-based tiers with a permanent free plan (500 notifications/month, unlimited mailboxes). Paid plans start at $29/month for 5,000 notifications, $99/month for 50,000, and $399/month for 250,000, all with unlimited mailboxes and 30-day event retention; higher tiers add priority and 24/7 support. The first 500 emails are free and no credit card is required to start.

- **Clean JSON webhooks:** Get granular, standardized events such as inbox.added, inbox.read, sent.added, drafts.added, spam.added, label.added and catch-all deletion events for both Gmail and Outlook.
- **Zero duplicate events:** Advanced deduplication stops the same Gmail message from firing more than once, so downstream systems never process duplicates.
- **Reliable delivery and replays:** Failed deliveries are retried with exponential backoff for roughly 1.5 hours, and all events are stored for 30 days so you can replay any delivery via the API.
- **One API for Gmail and Outlook:** A single REST API sends emails, lists messages, manages labels and migrates users across Gmail and Outlook with encrypted credential storage.
- **Automatic OAuth refresh:** Gmail watches and Outlook subscriptions are automatically renewed and OAuth credentials refreshed, eliminating ongoing maintenance work.

**Strengths:** Turns Gmail and Outlook into a single normalized webhook API; Built-in deduplication and exponential-backoff retries reduce engineering effort; Unified send/list/label API avoids provider-specific code; Free tier with 500 notifications per month and no credit card

**Limitations:** Requires OAuth setup and a publicly reachable webhook endpoint on your side; Compliance certifications (SOC 2, HIPAA, GDPR) are still listed as pending; No dedicated phone support on lower tiers; Pricing scales with notification volume, which can get costly at very high throughput

## 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
