The Problem
As indie developers, we’ve always struggled with marketing. Building the product is the fun part — the code, the design, the problem-solving. Marketing is the part that determines whether anyone actually uses what you built. And for most indie devs, marketing means either spending hours on manual tasks or spending hundreds of dollars per month on tools designed for companies 100x your size.
We surveyed the landscape of marketing tools when we launched Watashi Colorizer. Ahrefs: $99/month minimum, $199 for the features we actually needed. SEMrush: $129/month. HubSpot: free tier is crippled, useful tier starts at $800/month. Buffer for social media: $6/month per channel, reasonable but limited. Mailchimp for email: free tier caps at 500 contacts. Add it all up and you’re looking at $300-500/month before your product has earned a single dollar.
The math doesn’t work for indie developers. When your total revenue is $200/week and you’re spending $400/month on marketing tools, you’re giving back half your revenue to SaaS subscriptions. And most of those tools are designed for marketing teams of 5-20 people, not a solo developer wearing every hat.
What We Needed
We made a list of what we actually needed, stripped of enterprise features we’d never use. SEO monitoring: Lighthouse audits on a schedule, schema validation, keyword rank tracking. Social media: draft posts, schedule them, track basic engagement. Content: help writing blog posts, email campaigns, and ad copy. Analytics: understand where traffic comes from and what converts.
The key insight was that we didn’t need any of these tools to be best-in-class. We needed them all in one place, at a price point that makes sense for someone earning $800/month from their product. Ahrefs is the best keyword research tool in the world — but we don’t need the best. We need “good enough” keyword tracking bundled with “good enough” social scheduling bundled with “good enough” content drafting, all for a fraction of what any single specialized tool costs.
We also realized that AI could close the quality gap. A lot of what makes expensive marketing tools valuable is human expertise baked into the product — SEO recommendations, content suggestions, competitive analysis. Modern AI models can provide much of this analysis on demand, dramatically reducing the engineering effort needed to build useful marketing features.
Building the Solution
We started building Watashi Marketing in early 2026, initially as an internal tool for managing Watashi Colorizer’s marketing. The first feature was automated Lighthouse audits — we wanted to know immediately if a deploy broke our PageSpeed scores. That took a weekend to build: a scheduled job that runs PageSpeed Insights API, stores the results, and sends an alert if scores drop below thresholds.
The schema scanner came next. We were manually checking our structured data using Google’s Rich Results Test after every content change. Automating this was straightforward — fetch the page, parse the JSON-LD, validate against Schema.org specifications, generate recommendations using Gemini. What used to take 15 minutes of manual checking now happens automatically after every deploy.
Social media management was the feature that pushed us from “internal tool” to “product.” We integrated Twitter/X with OAuth, built an AI-powered post generator that understands our brand voice, and added a scheduling system. The AI generates post drafts based on our content, we review and approve them, and they publish automatically. This replaced an hour of daily social media work with 10 minutes of review.
We chose Google Gemini 2.0 Flash as our AI backbone. It’s fast, affordable, handles both text and image analysis, and produces high-quality output for marketing tasks. The cost per API call is low enough that AI-powered features don’t blow up our operating costs — which matters a lot when you’re building a tool for indie developers who are cost-sensitive.
What It Does Today
Watashi Marketing has grown from an internal tool into a full marketing platform. The core modules are: Architect (SEO audits, Lighthouse monitoring, schema scanning), Social Media (AI post generation, scheduling, analytics), Content (blog post drafts, email campaigns, ad copy), Brand Radar (mention monitoring), and Outreach (lead tracking).
The platform runs background jobs that continuously monitor your sites. Lighthouse audits run every few hours. Schema scans validate structured data automatically. Social media metrics update every 15 minutes. Alerts notify you when something needs attention — a score drops, a schema error appears, engagement spikes on a post. The goal is that you log in once a day, review the dashboard, approve some AI-generated content, and move on.
Everything is built around the indie developer workflow: one person managing marketing for one or a few products, spending minimal time, getting maximum impact. We use it ourselves for Watashi Colorizer and watashigames.com, so every feature gets real-world testing before it ships.
What’s Next
We’re actively developing an AI site builder within Watashi Marketing — the ability to generate entire landing pages optimized for SEO from the start. The idea is that an indie developer describes their product, and the AI generates a complete, deployable landing page with proper meta tags, schema markup, responsive design, and compelling copy.
We’re also expanding our competitor analysis features. Understanding what your competitors are doing — which keywords they rank for, what content they’re publishing, how their social presence compares to yours — is essential for strategic decisions. We’re building this with the same philosophy: good enough for indie developers, a fraction of the cost of enterprise tools.
If you’re an indie developer spending too much time or money on marketing, check out Watashi Marketing. We built it because we needed it, and we think you might need it too.
