Gravitec

Gravitec is a web push notification platform that helps website owners, publishers, and marketers convert visitors into subscribers and re-engage them through targeted push campaigns. With over 40,000 websites using the service, Gravitec positions itself as a more affordable alternative to competitors like OneSignal, combining automated push delivery with AI-generated message content trained on more than 100 billion sent notifications.

Key Features

One-click subscriber collection - Visitors opt in through a native browser prompt with no form filling required, helping sites build subscriber lists quickly without interrupting the user experience.
AI-powered message generation - Gravitec AI uses OpenAI models trained on push-specific performance data to generate headlines and body text optimized for higher click-through rates, adapting content specifically for the push notification format.
Automated campaigns - Drip campaigns, welcome messages, RSS-to-push, tweet-to-push, and daily or weekly content digests can run without manual intervention, reducing campaign management time by up to 90% according to the platform.
Advanced audience segmentation - Subscribers can be segmented by location, browser, device, operating system, language, and custom tags based on page visits or chosen interests. Alias segmentation enables personalized one-to-one campaigns.
Real-time analytics dashboard - Track sent, delivered, seen, and opened metrics for each campaign with benchmark comparisons, helping teams identify what content and timing produce the best results.
Subscriber migration support - Built-in tools transfer existing subscribers from other push notification services without requiring users to re-subscribe, making switching from competitors straightforward.

AI-Powered Content Generation

Gravitec AI is an integrated content assistant that generates push notification copy directly within the campaign builder. The system combines OpenAI's language models with proprietary training data derived from over 100 billion push campaigns delivered through the platform. Rather than producing generic marketing copy, it optimizes text for the constraints of push notifications, where character limits are tight and attention spans are short. The AI feature is available across all plans including the free tier, though generation usage may be subject to fair-use limits on lower plans.

Automation and Integrations

Gravitec provides five no-code automation workflows that reduce the need for manual campaign creation. The Drip Campaign builder sends sequenced notifications to new subscribers over time. The Welcome Message automation delivers a branded first notification immediately after opt-in. RSS to Push automatically creates campaigns from new RSS feed items, making it practical for news and blog sites. Tweet to Push converts new tweets containing URLs into push campaigns. The Daily and Weekly Digest feature automatically curates popular and unseen content for each subscriber into a personalized web page delivered via push. For more complex workflows, Gravitec integrates with Zapier, connecting to over 9,000 third-party applications including CRMs, e-commerce platforms, email tools, and social media schedulers.

Pricing and Plans

Gravitec offers three pricing tiers. The Free plan supports up to 10,000 notified subscribers with unlimited subscriber collection, unlimited websites, one user seat, unlimited notifications, and five automations per day. It lacks integrations, Safari browser support, and includes a "Powered by Gravitec.net" footer. The Fix plan costs 0 per month and raises the notified subscriber cap to 200,000, adds unlimited users, unlimited automations, and unlimited integrations. The Business plan removes all subscriber caps, adds priority support, and provides REST API access for custom implementations. Business pricing is custom-quoted based on volume. All plans support unlimited subscriber collection, meaning sites only pay based on how many subscribers they actively send notifications to.

Pros and Cons

Pros:

Straightforward per-subscriber pricing with a capable free tier that avoids forced upgrades for small sites
AI content generation is available on all plans, not locked behind a premium tier
Subscriber migration tools reduce the friction of switching from competing platforms
Zapier integration connects to a large ecosystem without requiring custom development
Unlimited websites and unlimited subscriber collection on every plan

Cons:

The free plan lacks integrations and includes mandatory Gravitec branding, reducing suitability for professional use without a paid upgrade
No Safari browser support on the free plan, limiting reach to macOS and iOS users who use Safari
iOS devices do not support web push notifications at all, which is an Apple-imposed limitation affecting all web push providers
REST API access is reserved for the Business plan, restricting programmatic campaign management for smaller accounts
The Fix plan's subscriber cap of 200,000 may require an upgrade to business pricing for mid-size publishers, where costs become less predictable

Who Should Use Gravitec

Gravitec suits website owners, bloggers, news publishers, and e-commerce operators who want to build a direct re-engagement channel outside of email and social media. The free plan provides enough capacity for small sites to test push notifications as a traffic channel before committing. Marketing teams that value automation will benefit from the RSS-to-push and digest features, which keep content flowing without daily manual effort. The AI generation feature adds particular value for teams without dedicated copywriters. Larger enterprises needing custom API integrations, unlimited subscriber volumes, or white-label branding should evaluate the Business plan. Sites whose audiences primarily browse on iOS or Safari should understand the platform limitations before adopting any web push provider.
