RelayFast is the right pick for a solo SaaS founder or tiny product team that wants changelog, feature requests, subscriber email, and an in-app widget without paying per tracked user. The AI assist is thin at 20 scans per month, and the free tier caps you at 50 subscribers and 10 posts, which is tight for anything beyond a proof-of-concept. If you need deeper analytics, segmentation, or NPS, look at a broader platform like AnnounceKit before committing here.
What is RelayFast?
RelayFast is a hosted product-update platform for small SaaS teams, combining a public changelog, feature request board, subscriber email notifications, and an embeddable in-app widget. A single post can simultaneously update the public changelog page, notify email subscribers, populate an RSS feed, and appear inside the product through the widget.
The platform is built around four capability areas: public page hosting with custom domain support, a feedback loop for collecting and tracking feature requests, a distribution layer for subscriber and in-app delivery, and a control plane for managing projects, categories, and branding. It is aimed at solo founders, product managers, and small product teams at SaaS companies who want to consolidate product communication without per-user pricing.
How we scored RelayFast
Capability lands at 17 because the four-area feature structure (public page, feedback loop, distribution, control plane) is genuinely more integrated than single-purpose changelog tools, but the AI layer is thin at 20 scans per month and there is no segmentation, analytics, or NPS, features that named competitors like AnnounceKit include. Ease of use scores 19 because the single-post-to-everywhere workflow is clearly designed for low friction and the pricing page is transparent, though no third-party usability data exists to validate the claim. Value scores 18 because $19/month with no per-user fees is fair for a small team, and the free tier is functional enough to test the workflow, but the 50-subscriber free cap and the 20 AI scan Pro cap both represent real limits that reduce the plan's practical value. Delivery scores 12 because the tool is early-stage with no third-party reviews found, sparse public sentiment, and a founder beta still in progress, making it impossible to verify that the product delivers reliably at scale; this is not a trust controversy but a genuine evidence gap that warrants caution.
Pros and cons
What we liked
- Flat pricing with no per-user or page-view fees means the monthly cost stays at $19 regardless of how many people view the changelog or use the product.
- Four capabilities in one workflow: public changelog, feature request board with voting and status tracking, subscriber email, and in-app widget, all driven from a single post.
- Free tier includes feature requests, voting, and an embeddable widget, which is more than most changelog-only free plans offer.
Where it falls short
- AI changelog scans are capped at 20 per month on Pro, which is low enough to be a real constraint for teams publishing frequently and wanting AI assistance on every post.
- The free tier's 50-subscriber and 10-posts-per-month limits are tight: a product with any real user base will hit the subscriber cap quickly and be forced to upgrade or lose the ability to notify new sign-ups.
- No user segmentation, engagement analytics, or NPS: teams that want to know which users read which update, or who to target with a specific announcement, will find the distribution layer too blunt.

Who should use RelayFast?
A solo founder shipping weekly updates who currently pastes release notes into a Notion page, a Slack message, and a manual email is the clearest fit. RelayFast replaces all three with one post and handles subscriber management, unsubscribe paths, and in-app visibility automatically. The flat $19/month Pro price and the absence of per-tracked-user fees make the cost predictable as the product grows, up to 1,000 subscribers.
Product managers at teams of two to five who already collect feature requests in a spreadsheet or a support inbox will also find the feedback loop useful: requests, votes, and statuses connect directly to shipped changelog entries, so customers can see when their feedback became a real release. If your team needs user segmentation, NPS, or detailed engagement analytics on who read which update, RelayFast does not have those features. Notion AI is a better fit if your team already lives in Notion and wants AI-assisted drafting across all your product docs, not just changelogs.
Skip it if: Teams needing user segmentation, NPS surveys, or analytics beyond basic subscriber counts.
RelayFast alternatives
Frequently asked questions
Is there a free plan, and what does it actually include?+
Yes. The free tier includes one project, 10 posts per month, 50 subscribers, a hosted changelog with RelayFast branding, feature requests and voting, an embeddable widget, and an RSS feed. There is no custom domain on the free plan.
How much does RelayFast Pro cost?+
Pro is $19 per month on monthly billing or $180 per year on annual billing, which works out to about $15 per month. The price is flat and does not change based on the number of tracked users or page views.
What happens if I cancel my Pro subscription?+
When you cancel, the project moves to the free plan automatically. Your published posts, subscribers, and feature requests are retained. Pro-only features like the custom domain and removed branding pause until you upgrade again.
Does RelayFast charge extra based on how many users view my changelog?+
No. RelayFast uses flat pricing on both plans. There are no tracked-user fees, monthly active user fees, or page-view overages.
What is the AI changelog scan feature and how limited is it?+
Pro includes 20 AI changelog scans per month. This is a light AI assist for drafting or reviewing posts, not a generative writing suite. Teams publishing more than a few updates per week will likely find the cap restrictive.
What is the founder offer and who qualifies?+
The first 20 SaaS founders get 3 months of Pro access free in exchange for honest product feedback, including reporting issues and becoming an early Product Hunt supporter. After the 3 months, billing continues at the standard Pro rate.
