Rate Forge: Calculate the Exact Hourly Rate You Need as a Freelancer

Rivier Grullon — Thu, 05 Mar 2026 22:24:40 +0000

Calculate your real minimum freelance rate — self-employment taxes, healthcare, overhead, and utilization all factored in.

🔗 Try it free: https://microsaas-lab.vercel.app/rate-forge

The Problem

Most freelancers set rates by looking at what others charge and picking a competitive-sounding number. This is how you end up working 50 hours a week but taking home far less than expected.

Freelance rates need to account for things employed workers never think about: self-employment taxes, healthcare, non-billable time.

Introducing Rate Forge

Rate Forge walks you through every cost factor: target take-home salary, self-employment taxes, healthcare, retirement contributions, overhead, vacation days, and realistic billable utilization. The output is the minimum you must charge.

Rate Forge is completely free, requires no account or installation, and runs entirely in your browser. Your data never leaves your machine.

Key Features

Target salary with take-home reverse calculation
Self-employment tax calculator
Healthcare premium input
Retirement contribution planning
Overhead costs (software, equipment, professional development)
Billable utilization rate — accounts for non-billable time
Minimum hourly rate with buffer recommendations

Who Is It For?

Freelancers of all types — developers, designers, writers, consultants — who want to set rates that actually cover their real costs.

Clean, normalize, and deduplicate messy lead lists and CRM exports in one click. Import-ready CSV in seconds.

🔗 Try it free: https://microsaas-lab.vercel.app/clean-my-leads

The Problem

Every sales team eventually ends up with a lead list disaster. Names in ALL CAPS mixed with lowercase, phone numbers in 6 different formats, emails with trailing spaces, duplicates everywhere.

CRM imports that fail validation are one of the most frustrating sources of wasted time in sales operations.

Introducing Clean My Leads

Clean My Leads applies intelligent normalization in one pass: standardizes phone formats, title-cases names, strips whitespace, deduplicates on email or phone, and produces an import-ready CSV for any CRM.

Clean My Leads is completely free, requires no account or installation, and runs entirely in your browser. Your data never leaves your machine.

Key Features

Standardizes email addresses (lowercase, trim whitespace)

Deduplicates by email and/or phone number
Flags missing required fields for manual review

Who Is It For?

Rivier Grullon — Thu, 05 Mar 2026 22:20:37 +0000

Paste any Twitter/X thread or wall of text and get a clean, distraction-free, printable version instantly.

🔗 Try it free: https://microsaas-lab.vercel.app/ThreadPrint

The Problem

Twitter/X threads contain some of the best expert knowledge on the internet — but reading them on the platform means fighting infinite scroll, retweet noise, ads, and trending topics.

Some of the best writing is trapped in thread format.

Introducing Thread2Print

Thread2Print converts any thread (or any wall of text) into a clean, readable, printable document. Paste the content, get back a beautifully formatted page you can read, print, or save as PDF — stripped of all platform noise.

Thread2Print is completely free, requires no account or installation, and runs entirely in your browser. Your data never leaves your machine.

Rivier Grullon — Thu, 05 Mar 2026 22:20:03 +0000

Generate YouTube chapter timestamps and podcast show notes from your recording notes in seconds. Stop manual time-coding.

🔗 Try it free: https://microsaas-lab.vercel.app/TimeStampNinja

The Problem

After finishing a 2-hour recording, you have to go back and manually write timestamps for every section. Scrub through the video, note the times, format them into YouTube chapter format, do it again for podcast show notes.

This can take 30-60 minutes per episode, every single time.

Introducing Timestamp Ninja

Timestamp Ninja takes your raw recording notes — even rough ones with approximate times — and formats them into publication-ready YouTube chapters and podcast show notes in one pass.

Timestamp Ninja is completely free, requires no account or installation, and runs entirely in your browser. Your data never leaves your machine.

BatchResize: Resize Images to Every Social Media Format in One Shot

Rivier Grullon — Thu, 05 Mar 2026 22:19:36 +0000

Resize your images to every social media format in one shot — Instagram, Twitter/X, LinkedIn, TikTok, and more. Zero uploads.

🔗 Try it free: https://microsaas-lab.vercel.app/batch-resizer

The Problem

Social media has fragmented image dimensions into a nightmare. Instagram wants 1:1, 4:5, and 16:9. Twitter wants 16:9. LinkedIn has its own sizes. Every piece of content requires resizing the same image 6-8 times.

For solo creators or small marketing teams, this is hours of repetitive work every week.

Introducing BatchResize

BatchResize processes all your social media formats in one pass. Upload your image, select your target platforms, and download all resized versions in a ZIP — processed entirely in your browser with no upload required.

BatchResize is completely free, requires no account or installation, and runs entirely in your browser. Your data never leaves your machine.

Key Features

Covers Instagram (Feed, Story, Reel), Twitter/X, LinkedIn, TikTok, Facebook, YouTube
Smart crop modes: center, face-aware, manual
Batch all platforms in one click

WebP Cruncher: Batch Convert Images to WebP for Faster Page Loads and Better SEO

Rivier Grullon — Thu, 05 Mar 2026 22:18:36 +0000

Batch convert and compress images to WebP for faster page loads and better SEO scores. No uploads, no limits, no watermarks.

🔗 Try it free: https://microsaas-lab.vercel.app/image-cruncher

The Problem

PageSpeed Insights keeps telling you to serve images in next-gen formats. WebP delivers 25-35% smaller files than JPEG or PNG. But converting your existing image library is tedious.

Most tools process server-side (a privacy concern), watermark the output, or limit batch size behind a paywall.

Introducing WebP Cruncher

WebP Cruncher converts your entire image library to WebP in a single batch, using the Canvas API directly in your browser. No file size limits, no watermarks, no uploads — drag in your images and download a ZIP.

WebP Cruncher is completely free, requires no account or installation, and runs entirely in your browser. Your data never leaves your machine.

Key Features

Batch convert any number of images to WebP
Quality slider (0-100) with live file size preview
Supports PNG, JPEG, GIF (first frame), and BMP input
Downloads all converted images as a ZIP
100% browser-based — no server uploads
No file size limits, no watermarks, completely free

Who Is It For?

Web developers, SEO professionals, site owners, and anyone improving page load speed.

Rivier Grullon — Thu, 05 Mar 2026 22:18:08 +0000

Render and screenshot any HTML POC inside mobile, tablet, or desktop device frames. Perfect for QA reports and client demos.

🔗 Try it free: https://microsaas-lab.vercel.app/pocViewer

The Problem

Presenting an HTML proof-of-concept to clients means either sending a raw HTML file, taking janky screenshots, or spinning up a hosted demo for a 5-minute review.

None of these are professional.

Introducing POC Nexus Pro

POC Nexus Pro renders your HTML file inside realistic device frames — iPhone, iPad, MacBook, desktop monitor — and lets you take clean screenshots without needing real devices.

POC Nexus Pro is completely free, requires no account or installation, and runs entirely in your browser. Your data never leaves your machine.

Renders HTML files inside mobile, tablet, and desktop device frames
Multiple device choices: iPhone, iPad, Android, MacBook, desktop

Responsive preview — test how your layout adapts
Multiple frame themes (light/dark bezels)

Bulk Redirect Validator: Validate Hundreds of URL Redirects in Seconds

Rivier Grullon — Thu, 05 Mar 2026 22:16:45 +0000

Validate hundreds of URL redirects by generating JS console scripts or cURL bash commands — no server access needed.

🔗 Try it free: https://microsaas-lab.vercel.app/redirect

The Problem

After a site migration you need to verify hundreds of redirects are working correctly. Doing this manually is impossible at scale, and most tools require uploading your URL list to a third-party service.

There's a better way that keeps your data private.

Introducing Bulk Redirect Validator

Bulk Redirect Validator generates JavaScript console scripts and cURL bash commands you run yourself to test redirect chains. Paste your URL pairs, get a test script, run it — no third-party server sees your URLs.

Bulk Redirect Validator is completely free, requires no account or installation, and runs entirely in your browser. Your data never leaves your machine.

Key Features

Input source and destination URL pairs in bulk
Generate JavaScript console test script (run in Chrome DevTools)
Generate cURL bash script (run in terminal)
Test for 301, 302, 307, 308 and final destination
Detect redirect chains and loops
Export results as CSV for client reporting

Who Is It For?

SEO professionals, web developers, digital agencies, and site admins managing URL migrations.

Scope Forge: Build Professional Freelance Estimates That Actually Close Deals

Rivier Grullon — Thu, 05 Mar 2026 22:15:47 +0000

Build professional project estimates for freelance clients in minutes. Break down scope, set rates, export a polished PDF quote.

🔗 Try it free: https://microsaas-lab.vercel.app/scoopeForge

The Problem

Freelancers often lose deals not because of price, but because of how they present it. A Google Doc with bullet points and a total number doesn't convey expertise or value.

Building a detailed, professionally formatted proposal from scratch for every client is time-consuming and inconsistent.

Introducing Scope Forge

Scope Forge is a structured estimate builder: scope breakdown, deliverables, timeline, rates, and terms. The output is a polished PDF proposal that looks like it came from an agency — not a Google Doc.

Scope Forge is completely free, requires no account or installation, and runs entirely in your browser. Your data never leaves your machine.

Key Features

Structured scope builder — deliverables, phases, and milestones
Hourly or fixed-price estimate modes
Time estimate breakdown per deliverable
Payment terms and deposit configuration
Professional PDF export with your branding
Save and reuse estimate templates

Who Is It For?

Freelancers, consultants, and small agencies who want to present more professional estimates and reduce price negotiation.

Sheet2Mock: Convert Excel/Google Sheets Data to Clean JSON + TypeScript Interfaces

Rivier Grullon — Thu, 05 Mar 2026 22:14:57 +0000

Paste your spreadsheet data and instantly get clean JSON mock data plus TypeScript interfaces. Zero config, 100% in-browser.

🔗 Try it free: https://microsaas-lab.vercel.app/sheet-to-json

The Problem

Frontend developers often wait weeks for real API data before they can build and test UIs. The workaround is writing mock data by hand — creating JSON arrays, TypeScript interfaces, keeping both in sync as the schema evolves.

This is repetitive, error-prone, and boring.

Introducing Sheet2Mock

Sheet2Mock converts your spreadsheet data (pasted from Excel or Google Sheets) into a JSON array and TypeScript interface definition in one step. Paste your data with headers, get production-ready mocks to drop directly into your codebase.

Sheet2Mock is completely free, requires no account or installation, and runs entirely in your browser. Your data never leaves your machine.

Key Features

Paste CSV or tabular data from Excel or Google Sheets
Generates clean JSON array with inferred data types
Generates TypeScript interface matching the schema
Type inference: detects strings, numbers, booleans, dates
One-click copy for JSON and TypeScript separately
100% in-browser — no API calls, no uploads

Who Is It For?

Frontend developers who need mock data before the backend is ready, and anyone who receives data requirements in spreadsheet format.

Clip2Vault: Transform Kindle Highlights into a Clean Markdown Vault

Rivier Grullon — Thu, 05 Mar 2026 22:13:48 +0000

Convert your Kindle My Clippings.txt file into a clean, organized Markdown vault. Group highlights by book and import directly into Obsidian, Notion, or any PKM system.

🔗 Try it free: https://microsaas-lab.vercel.app/Clip2Vault

The Problem

If you're a Kindle reader, you know the pain: your My Clippings.txt file is a disaster. One long, unsorted wall of text mixing hundreds of books, duplicate clips, and formatting noise.

Amazon doesn't give you an easy export. Third-party tools want subscriptions or require cloud uploads. And the raw file is simply unusable for building a proper reading knowledge base in Obsidian or Notion.

Introducing Clip2Vault

Clip2Vault parses your My Clippings.txt and produces clean, organized Markdown files — one per book, with all highlights deduped, formatted, and ready to drop into your PKM system. No cloud. No account. Just drag, drop, and download.

Clip2Vault is completely free, requires no account or installation, and runs entirely in your browser. Your data never leaves your machine.

Key Features

Parses the entire Kindle My Clippings.txt in seconds
Groups highlights by book automatically
Deduplicates overlapping or repeated clips
Outputs clean Markdown compatible with Obsidian, Notion, and Logseq
100% browser-based — your data never leaves your device

Who Is It For?

Avid Kindle readers who use PKM systems like Obsidian or Notion, and students building a reading knowledge base.

Rivier Grullon — Thu, 05 Mar 2026 22:13:23 +0000

Import your BoardGameGeek collection and get game-night suggestions filtered by player count, playtime, and weight. Decide in under 60 seconds.

🔗 Try it free: https://microsaas-lab.vercel.app/TableTopPick

The Problem

You have 80 board games, 6 people are coming over, and nobody can agree what to play. You spend 20 minutes scrolling BoardGameGeek.

BoardGameGeek is a fantastic database, but it was not designed for the "what do we play tonight?" question.

Introducing TableTop Pick

TableTop Pick imports your BGG collection and filters it instantly by player count, playtime, and game weight/complexity. Get a short list of games that actually fit tonight, with a randomizer for when you still can't decide.

TableTop Pick is completely free, requires no account or installation, and runs entirely in your browser. Your data never leaves your machine.

Key Features

Import your BoardGameGeek collection with your username
Filter by player count, playtime range, and weight/complexity

Randomizer mode — let fate pick from your filtered list
100% browser-based, no account required
