Last month I audited my SaaS subscriptions and realized I was paying $150/month for tools I used once or twice a week. So I spent a weekend finding free alternatives that actually work.
Here's what I replaced and what I switched to.
What I Cut
- JSON formatter extension ($9/mo) → Free browser tool
- Markdown editor ($12/mo) → Free browser tool
- Password generator app ($6/mo) → Free browser tool
- Color picker tool ($8/mo) → Free browser tool
- Code beautifier ($10/mo) → Free browser tool
- Regex tester ($7/mo) → Free browser tool
- Base64 encoder ($5/mo) → Free browser tool
- Cron job builder (part of dev tools bundle) → Free browser tool
- Hash generator (part of dev tools bundle) → Free browser tool
- JWT decoder ($5/mo) → Free browser tool
- UUID generator (part of dev tools bundle) → Free browser tool
- QR code generator ($8/mo) → Free browser tool
- Word counter (part of writing bundle) → Free browser tool
- URL encoder (part of dev tools bundle) → Free browser tool
- Lorem ipsum generator (part of design bundle) → Free browser tool
The Free Tools I Use Now
All of these are browser-based, no signup required, and run client-side where possible:
For coding & debugging:
- JSON formatter/validator — paste minified JSON, get pretty-printed output with error highlighting
- Regex tester — real-time matching with capture group visualization and cheat sheet
- Base64 encoder/decoder — text and file encoding in one click
- Code beautifier — minified HTML, CSS, JS, JSON back to readable format
- Hash generator — MD5, SHA-256, SHA-512, all client-side
- JWT decoder — inspect token payload, check expiry, debug auth flows
- UUID generator — v4 UUIDs, single or bulk
- Cron job builder — visual schedule builder with human-readable explanation
For writing & content:
- Markdown editor — live preview, export to HTML/PDF
- Word counter — character, sentence, paragraph count + reading time
- Lorem ipsum generator — realistic placeholder data (names, emails, addresses)
For design & frontend:
- Color picker — HEX/RGB/HSL conversion + palette generation + WCAG contrast checker
- QR code generator — SVG and PNG export, customizable
- URL encoder/decoder — percent-encoding for API parameters
Why Browser Tools Work Better Than You Think
- Zero install — no extensions, no desktop apps, no npm packages. Open browser tab, done.
- Always up to date — no version management, no breaking changes from updates
- Cross-platform — works on any OS, any browser, any machine
- No vendor lock-in — no account needed, no subscription, no data stored on someone's server
- Shareable — send a URL to a teammate and they have the exact same tool
The One Catch
You need to bookmark them. I keep mine in a "Dev Tools" folder in my browser bar. Takes 2 seconds to set up.
The Full Collection
I ended up finding 68 free tools organized by category. JSON, regex, encoding, crypto, text, colors, generators — everything I was paying for individually, all in one place.
All client-side where possible. No tracking, no paywalls, no email collection.
What I Do With The Savings
$150/month = $1,800/year. That's a new laptop every 2 years, or a conference trip, or just... keeping the money.
The ROI on finding free alternatives is massive, especially for utilities you use infrequently. You don't need a $9/month subscription for a tool you open twice a week.
