DEV Community: ToolSphare

A Free SEO Toolkit for Freelancers in Nigeria, Kenya and Ghana

By Muhammad Wasim, developer of ToolSphare

Freelance SEO and web design work is popular across Africa's tech hubs, from Lagos and Accra to Nairobi and Kampala. Many freelancers serve local businesses that are just getting online, as well as international clients found through freelance marketplaces. Either way, the work is similar: audit pages, fix on-page problems, set up tracking, and prove that things improved.

The catch is cost. Premium SEO suites are priced in dollars on monthly subscriptions, which is a serious expense when you are starting out or when your clients are small businesses. The good news is that a large share of on-page SEO work does not need a premium suite at all.

I am the developer of ToolSphare, a free collection of browser tools, and below is the SEO toolkit I would hand to a freelancer starting today. Every tool is free and needs no sign-up.

Step 1: Audit what is already on the page

Meta Tag Analyzer

Start every audit by checking the basics. Paste a page's HTML into the meta tag analyzer to review the title, meta description, canonical and social tags in one view.

Heading Structure Analyzer

Clients' pages often have no H1, three H1s, or headings that skip levels. The heading structure analyzer audits the H1 to H6 hierarchy and flags missing or skipped levels.

Keyword Density Checker

To see what a page is actually about, run its text through the keyword density checker. It shows top words and their frequency, which helps you spot both keyword stuffing and pages that never mention the main topic.

Readability Checker

Content written for a local audience should be easy to read. ToolSphare's readability checker scores text with the Flesch Reading Ease formula and grade-level estimates, a useful, objective point to include in a client report.

Step 2: Fix and generate the tags

SERP Snippet Preview

Before you change a title or description, show the client what it will look like. The SERP snippet preview simulates how the page may appear in Google results, which makes approval conversations much easier.

Open Graph and Twitter Card Generator

Many small businesses get most of their traffic from WhatsApp, Facebook and X shares. A broken preview image or missing title hurts click-through. Use the Open Graph generator to create complete Open Graph and Twitter Card tags with a live preview.

Schema Markup Generator

Structured data helps search engines understand a page. The schema markup generator builds JSON-LD for types such as Article, FAQ and Product, ready to paste into the page's head.

Canonical Tag Generator

Duplicate URLs (with and without "www", with tracking parameters, or with trailing slashes) are common on small sites. Generate correct canonical tags to tell search engines which version to index.

Hreflang Tag Generator

If a client publishes in English and French (common in West and Central Africa) or English and Swahili, use the hreflang tag generator to produce valid language tags and sitemap snippets.

Step 3: Help search engines crawl the site

Robots.txt Generator

A misconfigured robots.txt can hide a whole site from Google. Create a clean file with common crawl rules using the robots.txt generator.

XML Sitemap Generator

For small sites without a CMS plugin, build a sitemap.xml from a list of URLs and submit it in Google Search Console.

Step 4: Track results

UTM Campaign Link Builder

When a client runs a WhatsApp broadcast, an Instagram campaign or a radio promotion with a website link, you want to see the traffic separately in analytics. ToolSphare's UTM builder creates tagged URLs for Google Analytics 4 with source, medium and campaign parameters.

Anchor Text Analyzer

If you are doing link building, the anchor text analyzer groups a backlink profile's anchors into exact, partial, branded and generic types, so you can see whether the profile looks natural.

Putting it together for a client

Here is a simple, honest service package a freelancer can offer a local business:

Audit: run the homepage and key service pages through the meta tag, heading and readability tools, and record the issues.
Fix: write new titles and descriptions, check them in the SERP preview, and add Open Graph and schema tags.
Crawlability: generate robots.txt and a sitemap, and submit the sitemap.
Tracking: give the client UTM links for every campaign.
Report: show before-and-after screenshots and the analytics data that the UTM links collect.

None of that requires a paid subscription, which means you can price your services fairly for small businesses while keeping your own costs low.

A note on honesty in SEO

Free tools make it easy to move fast, but good SEO is still about useful content and a site that works well. Avoid promising rankings, avoid spammy link schemes, and be open with clients about what you changed and why. That reputation is worth more than any tool.

A Free Website and Security Check-Up Kit: 15 Tools for Site Owners and IT Teams

ToolSphare — Sun, 15 Nov 2026 00:02:45 +0000

By Muhammad Wasim, Software Engineer and developer of ToolSphare

Websites rarely fail dramatically. More often, something small goes wrong quietly: an SSL certificate expires over a weekend, a DNS change never propagates, a redirect loop breaks the checkout, or an email domain without proper records starts landing in spam. Small businesses and solo developers usually find out when a customer complains.

A regular check-up prevents most of this, and it does not need expensive monitoring software. Below is the free kit I use, built into ToolSphare. Every tool runs in the browser, and none needs a sign-up.

Part 1: Domain and DNS

WHOIS Domain Lookup

Start with the domain itself. The WHOIS lookup runs real-time WHOIS and RDAP queries to show the registrar, expiry date, domain age and status. Domain expiry is one of the most avoidable outages, so note the date somewhere you will see it.

DNS Record Lookup and Propagation Checker

After changing hosting or email providers, use the DNS lookup checker to inspect A, AAAA, MX, CNAME, TXT, NS and SOA records. It queries public DNS-over-HTTPS resolvers, which helps confirm whether a change is visible.

Domain Age Checker

When evaluating a domain to buy or a site to partner with, the domain age checker summarises registration dates, registrar, DNS, SSL and other website details in one report.

Part 2: HTTPS and HTTP behaviour

SSL Certificate Checker

The SSL certificate checker shows certificate health, days until expiry, the issuing certificate authority and handshake details. Free certificates such as Let's Encrypt renew automatically only if renewal is configured correctly, so this is worth checking monthly.

HTTP Status and Redirect Chain Checker

Redirect chains slow pages down and can confuse search engines. The HTTP status checker shows response codes such as 200, 301, 404 and 500, along with headers and each hop in the redirect chain.

HTTP Security Headers Checker

Security headers are a cheap, effective layer of protection. The security headers checker audits HSTS, Content-Security-Policy, X-Frame-Options and related headers so you can see what is missing.

Part 3: Email authentication

DMARC and SPF Record Generator

If your domain has no SPF or DMARC records, attackers can more easily spoof emails from it, and legitimate mail is more likely to land in spam. The DMARC and SPF generator creates and validates the DNS TXT records you need. Start with a monitoring policy and tighten it once reports look clean.

Part 4: Passwords, keys and secrets

Password Generator

Weak and reused passwords remain one of the most common ways accounts get compromised. Use the strong password generator to create random passwords with your chosen length and character sets, and store them in a password manager.

Password Strength Checker

To test an existing password without sending it anywhere, the password strength checker runs locally in the browser.

TOTP 2FA Code Generator

For developers testing two-factor authentication, the TOTP generator produces time-based codes from a Base32 secret in the browser. Use it with test secrets, not your personal accounts.

RSA Key Pair Generator

The RSA key generator creates 2048-bit or 4096-bit public and private key pairs in standard PEM formats, useful for development and testing.

Bcrypt Hash Generator

When building a login system, the bcrypt generator creates and verifies bcrypt password hashes with a configurable cost factor, so you can check your application's hashing logic.

File Hash Generator

Before installing software or sharing a large file, compare its checksum. The file hash generator computes SHA-256, MD5, SHA-1 and SHA-512 hashes locally in your browser.

Part 5: Safe content

HTML Sanitizer

If you accept HTML from users (comments, rich-text fields, CMS imports), unsafe markup can carry scripts. The HTML sanitizer strips dangerous tags and event handlers with a live preview, helpful for testing what your own sanitisation should remove.

Text Encryptor

To share a short secret note with a colleague, the AES-256 text encryptor encrypts and decrypts text client-side with a passphrase you share separately.

A monthly 15-minute check-up

WHOIS: confirm the domain expiry date is comfortably far away.
SSL checker: confirm the certificate is valid and renewing.
DNS lookup: confirm MX, SPF and DMARC records are present.
Status checker: test the homepage and checkout for redirect chains or errors.
Security headers: compare against last month and fix anything new.

Record the results in a simple spreadsheet so you can spot changes over time.

Responsible use

These tools are for checking and protecting systems you own or are authorised to manage. Generate keys and test 2FA with test data, keep real secrets in proper secret managers, and never use any tool to access accounts or systems that are not yours.

Frequently asked questions

Do I need command-line skills to use these tools?
No. They give you the same kind of information as tools like dig, whois and openssl, but in a simple web form.

How often should I run these checks?
Monthly is a sensible baseline for small sites, plus an immediate check after any hosting, DNS or certificate change.

Is it safe to generate keys in a browser?
For development and testing, yes. For production keys that protect real systems, follow your organisation's key-management policy and generate keys in controlled environments.

16 Browser-Based Developer Tools I Keep Open in a Tab (All Free)

ToolSphare — Sun, 15 Nov 2026 00:00:52 +0000

By Muhammad Wasim, Software Engineer and developer of ToolSphare

Every developer has a list of tiny jobs that interrupt real work: making a minified API response readable, checking what is inside a token, turning a curl command into code, or remembering which chmod number means what. Each job takes seconds once you have the right tool, and minutes when you go hunting for one.

I build and maintain ToolSphare, and its developer section started as my own collection of these helpers. Everything runs in the browser, there is nothing to install, and there is no sign-up. Here are the sixteen I use most, grouped by the type of work.

Working with JSON and data formats

JSON Formatter and Validator

The one I open most. The JSON formatter beautifies nested JSON with 2- or 4-space indentation, minifies it again for production, and highlights syntax errors with the exact line and character. Parsing runs client-side, so API payloads are not sent anywhere.

JSON Diff

When an API response changes between two versions, eyeballing the difference is painful. Compare two JSON objects side by side and see added, removed and changed values highlighted.

JSON to TypeScript

Paste a real API response into ToolSphare's JSON to TypeScript generator and get interfaces or type aliases back. Options include readonly fields and marking every property optional, which saves a lot of typing on a new integration.

YAML Validator and TOML to JSON

Configuration bugs are often a single bad indent. The YAML validator lints YAML with line-by-line error indicators. For Rust or Python projects, convert TOML to JSON or YAML with live syntax validation.

CSV to SQL

Importing a spreadsheet into a database? Generate SQL CREATE TABLE and INSERT statements from CSV, with column data types inferred automatically.

APIs, HTTP and tokens

cURL to Code

API docs love curl examples; your codebase does not. The cURL to code converter turns a command into JavaScript (Fetch or Axios), Python Requests, PHP and other languages.

HTTP Request Tester

To poke an endpoint without opening a full API client, the online HTTP request tester sends GET, POST, PUT and DELETE requests with custom headers and query parameters.

JWT Decoder

Need to check a token's claims or expiry? Decode a JWT in your browser and see the header and payload as formatted JSON. Decoding locally matters here, because tokens are credentials.

URL Parser

Long tracking URLs are hard to read. The URL parser breaks any URL into protocol, host, port, path and individual query parameters.

DevOps and servers

Docker Run to Compose

Turning a long docker run command into a tidy docker-compose.yml, with ports, volumes and environment variables, is tedious by hand. Convert docker run to Compose instead.

Nginx Config Generator

The Nginx config generator produces server blocks with reverse proxy, SSL/TLS, PHP-FPM and security headers. Always review generated configs before deploying, but it is a solid starting point.

Cron Expression Generator

Nobody remembers cron syntax. Build the schedule visually with the cron expression generator and read a plain-English explanation of what it means.

Linux chmod Calculator

Tick the read, write and execute boxes in the chmod permissions calculator and get the numeric code (such as 755 or 644) and the symbolic notation.

Subnet and CIDR Calculator

For network work, the subnet calculator shows subnet masks, usable host ranges, and network and broadcast addresses for any IPv4 CIDR block.

Front-end helpers

Regex Tester

Write a pattern, paste sample text, and see matches highlighted live with the regex tester. Flags are supported, so you can test case-insensitive or global matching.

How I use these in practice

A typical debugging session looks like this: I copy a failing request from the browser's network tab as curl, convert it with cURL to Code to reproduce it in a script, format the response in the JSON Formatter, diff it against a known-good response with JSON Diff, and decode the auth token with the JWT Decoder to check its expiry. Five tools, one tab, no installs.

A note on privacy

Developer data is often sensitive: tokens, internal URLs and customer records. Many of these ToolSphare tools state that they process data client-side. Even so, my advice is the same for any web tool: never paste production secrets into a site unless you understand how it handles them, and rotate any credential you accidentally expose.

Frequently asked questions

Are these tools a replacement for my IDE or API client?
No. They are for quick, one-off jobs, the moments when opening a full application or writing a throwaway script would take longer than the task itself.

Can I use them on a locked-down work laptop?
Usually yes. Because they run in the browser, there is nothing to install, which is often the main obstacle on corporate machines.

Do generated configs work as they are?
Treat generated Nginx, Docker Compose or cron output as a well-structured starting point. Review it against your environment, test it on staging, and only then deploy.
