Your hour, on every dashboard

SparkAds is an advertising network built for indie apps, priced so a solo developer can actually use it. The day is split into 24 hourly slots and each slot belongs to exactly one advertiser, network-wide. For $9 a month (or $90 a year) your app's card runs in the sponsored carousel on every dashboard in the Spark network during your hour, every day. Suggested slots target the evening attention peak in your chosen country, so a UK app reaches people at 8pm UK time, not 3am. No auction, no bidding, no minimum spend; the price is the price. Every creative is reviewed by a human before it goes live, and your card is rendered from your own site's favicon and colours so it looks native rather than pasted on. You get impression and click stats per app, per day and per traffic source on your own dashboard, can check your numbers from Claude via the built-in MCP server, and billing runs on SparkPay with cancel-anytime subscriptions.

Land interviews with optimized CVs

Most CVs are rejected by software before a person ever reads them. Still Applying is a free resume builder that keeps you on the right side of that filter. A guided wizard walks you through each section while a live score shows how well an applicant tracking system will parse what you have written. Import an existing CV from PDF and it fills itself in. Export to PDF, DOCX, Markdown, a shareable link, or a playable game version. No signup needed to start.

Billed once, apps forever

Doing Stripe properly means building a backend nobody wants to build: webhook handlers, subscription state, price objects, receipts, customer records. SparkPay is that backend, already built and hosted. Deploy it once, register an app, and drop the pricing page URL into your product. No Stripe SDK on the client, no code changes. One deployment serves unlimited apps, each isolated, with subscription status available from a single REST endpoint.

Chat AI for websites

Give any app a support agent that actually knows the product. SparkAI hosts a specialised AI agent per app, grounded in your own FAQs and live database, so answers come from your data instead of being invented. It chats, speaks, and takes phone calls. Embedding is one script tag, with no API keys sitting in client code. Authentication, rate limiting, moderation and billing are handled server side. Point it at your domain and it configures itself.

Boost SaaS visibility

Launching a SaaS product and then waiting to be found is not a strategy. Sellular gets you listed. It generates a tailored profile for each of 100+ curated directories, so you are not pasting the same tired blurb into a hundred forms. It also handles the technical side of being discovered: llms.txt and robots.txt for AI crawlers, branded Open Graph cards, a site audit that tells you what is actually costing you visibility, and outreach templates for directory owners.

Boost social media presence

Posting to nine platforms by hand is a part-time job nobody wants. Viral Cat turns it into a folder. Drop your content into Google Drive and it handles the rest: scanning what is trending right now, scoring how likely something is to travel, writing branded captions and visuals, and publishing on a schedule to Instagram, Threads, TikTok, YouTube, X, LinkedIn, Reddit, Bluesky and Pinterest. Built for creators and small teams who would rather make things than post them.

Cast your messages across the digital ocean

A professional email address on your own domain, without moving inbox. Bottled routes mail sent to hello@yourdomain.com straight into the Gmail you already use, and sends outbound mail from that branded address with DKIM and SPF properly configured. Free to start, no card required. Paid tiers add campaigns with open and click tracking, a built-in CRM with tags and engagement scoring, auto-reply, a team inbox, and a REST API.

One deploy, unlimited apps
