DevToolStack Update: Faster Browser Tools

Ashok Vavare — Sun, 31 May 2026 09:42:59 +0000

I kept refining DevToolStack around one simple idea: developer tools should get to the input box fast.

A lot of online utilities spend the first screen on large marketing sections. For debugging work, that adds friction. So I tightened the layout, added clearer no-login and runs-in-browser signals, and expanded the toolset around backend, API, SQL, URL, regex, and payload workflows.

Current tools include:

Redirect Checker for status chains and canonical URL checks
Regex Tester and Regex Explainer for matching plus pattern understanding
SQL Formatter, JDBC URL Parser, DDL Extractor, and explain-plan utilities
JSON, XML, YAML, Base64, JWT, hash, timestamp, URL, and cURL conversion tools

Main site:
https://www.devtoolstack.in/

Useful debugging workflows:

Redirect Checker: https://www.devtoolstack.in/redirect-checker/
cURL to Fetch Converter: https://www.devtoolstack.in/curl-to-fetch/
SQL Formatter: https://www.devtoolstack.in/sql-formatter/

The goal is compact, fast, free, and practical: no login, direct tool URLs, copy/download output where useful, and browser-side execution for most tools.

If you use small browser utilities during debugging, I would appreciate feedback: which workflow should be improved next?

DevToolStack: Free Browser-Based Tools for Backend, API, SQL, and Debugging Workflows

Ashok Vavare — Fri, 29 May 2026 20:00:38 +0000

Developers spend a lot of time on small debugging tasks that are not really the main work.

You are trying to fix an API issue, but first you need to decode a token. You are checking a database bug, but first you need to format a messy SQL query. You are reviewing an integration, but first you need to parse a long callback URL, inspect a redirect chain, convert a timestamp, or beautify a payload from logs.

Each task is small. The friction comes from doing them again and again across different websites, scripts, browser tabs, editor plugins, and command-line snippets.

That is why I built DevToolStack.

DevToolStack is a free collection of browser-based developer tools for SQL, APIs, encoders, parsers, formatters, timestamps, hashes, and backend debugging workflows.

Main site:

https://www.devtoolstack.in/

The idea is simple: fast tools, focused pages, direct URLs, no login, and a compact UI that gets you to the input/output area quickly.

What makes DevToolStack different?

There are many individual formatter, encoder, and debugging utilities online. DevToolStack is different because it is designed around the full developer workflow rather than one isolated task.

1. The tools are grouped around real debugging flows

A backend issue often touches multiple formats and layers:

an API request
a URL or redirect
a token
a timestamp
a SQL query
a payload
a hash or encoded value
a database connection string

DevToolStack keeps these related tools close together so you can move naturally between them.

For example:

Use cURL to Fetch Converter to turn API docs into browser-ready code.
Use JSON Formatter to inspect the response payload.
Use JWT Decoder if the request has an auth token.
Use URL Parser if a callback URL breaks.
Use Redirect Checker if the request is being forwarded unexpectedly.

2. Every tool has a direct, bookmarkable URL

Each tool has its own focused page:

SQL Formatter: https://www.devtoolstack.in/sql-formatter/
JSON Formatter: https://www.devtoolstack.in/jsonformatter/
XML Formatter: https://www.devtoolstack.in/xml-formatter/
YAML Formatter: https://www.devtoolstack.in/yaml-formatter/
Regex Tester: https://www.devtoolstack.in/regex-tester/
Regex Explainer: https://www.devtoolstack.in/regex-explainer/
Redirect Checker: https://www.devtoolstack.in/redirect-checker/
cURL to Fetch Converter: https://www.devtoolstack.in/curl-to-fetch/
URL Parser: https://www.devtoolstack.in/url-parser/
URL Encoder / Decoder: https://www.devtoolstack.in/url-encoder-decoder/
JWT Decoder: https://www.devtoolstack.in/jwt-decoder/
Base64 Encoder / Decoder: https://www.devtoolstack.in/base64-tool/
Timestamp Converter: https://www.devtoolstack.in/timestamp-converter/
Hash Generator: https://www.devtoolstack.in/hash-generator/
UUID Generator: https://www.devtoolstack.in/uuid-generator/
Cron Parser: https://www.devtoolstack.in/cron-parser/
User-Agent Parser: https://www.devtoolstack.in/user-agent-parser/
Chmod Calculator: https://www.devtoolstack.in/chmod-calculator/
JDBC URL Parser: https://www.devtoolstack.in/jdbc-url-parser/
DDL Extractor: https://www.devtoolstack.in/ddl-extractor/
Explain Plan Visualizer: https://www.devtoolstack.in/explain-plan-visualizer/
PL/SQL Dependency Extractor: https://www.devtoolstack.in/plsql-dependency-extractor/

This makes it easy to save the exact tool you need, share it in a ticket, or link it in internal docs.

3. No login, no setup, no heavy workflow

Most DevToolStack tools are designed to run directly in the browser. The common workflow is:

Paste input
Run the tool
Copy or download the result
Move on

That matters when you are debugging quickly, helping someone on a call, working from a restricted machine, or just checking something before writing code.

4. Compact UI instead of oversized landing pages

A lot of tools waste the first screen with huge headings, banners, and marketing blocks. DevToolStack is intentionally compact. The important part is the tool itself: input, output, actions, and clear feedback.

Most pages include quick trust signals like:

No login
Runs in browser
Copy/download output

The goal is to reduce the time between opening a page and getting useful output.

Tool highlights

SQL and database tools

SQL Formatter

https://www.devtoolstack.in/sql-formatter/

The SQL Formatter helps clean messy SQL and PL/SQL scripts so they are easier to read, review, and debug.

Useful for:

formatting long SELECT queries
reviewing joins and filters
cleaning migration scripts
preparing SQL snippets for documentation
formatting decoded or legacy stored logic

This is especially helpful when SQL comes from logs, tickets, chat messages, or exported files.

JDBC URL Parser and Builder

https://www.devtoolstack.in/jdbc-url-parser/

JDBC connection strings can be hard to read when they include hosts, ports, database names, service names, and query parameters. This tool parses the URL into readable parts and helps build cleaner connection strings.

Useful for:

checking wrong host or port values
inspecting connection parameters
comparing database URLs between environments
preparing Java application configuration

DDL Extractor

https://www.devtoolstack.in/ddl-extractor/

Large schema scripts often contain many objects in one file. The DDL Extractor splits object definitions so they are easier to inspect.

Useful for:

reviewing CREATE TABLE scripts
splitting indexes, views, triggers, packages, procedures, and functions
preparing database migration notes
isolating one object from a large schema dump

Explain Plan Visualizer

https://www.devtoolstack.in/explain-plan-visualizer/

Explain plans can be dense and difficult to scan. This tool helps turn plan text into a more readable structure for review.

Useful for:

understanding query execution steps
reviewing plan operations
sharing plan summaries with teammates
debugging performance issues

PL/SQL Dependency Extractor

https://www.devtoolstack.in/plsql-dependency-extractor/

This tool helps scan PL/SQL scripts for dependency clues such as table names, package calls, procedure calls, dynamic SQL, and other references.

Useful for:

migration planning
impact analysis
documentation
code review
support investigations

API and web debugging tools

Redirect Checker

https://www.devtoolstack.in/redirect-checker/

Redirect bugs are common in login flows, canonical domains, CDN rules, proxy configuration, and HTTP-to-HTTPS migration work.

The Redirect Checker helps inspect:

each redirect hop
status codes
final destination
redirect loops
canonical URL behavior

Instead of only seeing where a URL finally lands, you can understand the full redirect chain.

cURL to Fetch Converter

https://www.devtoolstack.in/curl-to-fetch/

API documentation often gives examples in cURL, but frontend debugging usually needs JavaScript fetch code.

This tool converts cURL commands into browser-ready fetch snippets.

Useful for:

translating API docs into frontend examples
preserving headers and body payloads
handling POST, PUT, PATCH, and GET examples
debugging auth and content-type issues
converting header-only checks like curl -I

URL Parser and Query Params Viewer

https://www.devtoolstack.in/url-parser/

Long URLs become painful when they contain nested redirect targets, UTM parameters, encoded values, fragments, repeated keys, or callback URLs.

The URL Parser splits a full URL into readable parts:

protocol
host
path
fragment
query parameters
decoded values
structured JSON output

This is useful for OAuth callbacks, analytics links, deep links, and API request debugging.

URL Encoder / Decoder

https://www.devtoolstack.in/url-encoder-decoder/

URL encoding bugs are small but painful. A missing encoded ampersand or slash can break a redirect, corrupt a query parameter, or change how a server interprets a request.

This tool helps encode and decode URL values quickly.

Useful for:

encoding redirect URLs
decoding server logs
fixing query strings
inspecting webhook callbacks
debugging nested URL parameters

User-Agent Parser

https://www.devtoolstack.in/user-agent-parser/

User-agent strings are hard to read manually. This tool parses them into readable browser, device, platform, and engine details.

Useful for:

support tickets
browser-specific bugs
analytics inspection
debugging device-specific behavior

Payload and data formatting tools

JSON Formatter

https://www.devtoolstack.in/jsonformatter/

JSON shows up everywhere: API responses, logs, configs, queues, webhooks, browser storage, and test fixtures.

The JSON Formatter helps:

format JSON
validate JSON
minify JSON
copy formatted output
download JSON files

This is one of the most common tools during API debugging.

XML Formatter

https://www.devtoolstack.in/xml-formatter/

Even if your current stack mostly uses JSON, XML still appears in SOAP integrations, vendor feeds, config files, identity systems, and enterprise workflows.

The XML Formatter helps format:

SOAP payloads
XML config files
vendor XML feeds
namespace-heavy documents
compressed XML from logs

It also helps make SOAP faults and nested XML easier to inspect.

YAML Formatter

https://www.devtoolstack.in/yaml-formatter/

YAML is common in CI/CD, infrastructure, Kubernetes, deployment files, and application configuration.

The YAML Formatter helps normalize indentation and make config files easier to review.

Useful for:

deployment configuration
CI pipeline files
infrastructure snippets
config review before commits

Encoding, token, and verification tools

JWT Decoder

https://www.devtoolstack.in/jwt-decoder/

JWT debugging often starts with simply inspecting the token.

The JWT Decoder helps read:

header
payload
claims
expiry values
issued-at values
audience and issuer fields

It is useful during auth debugging, token inspection, and API troubleshooting.

Base64 Encoder / Decoder

https://www.devtoolstack.in/base64-tool/

Base64 appears in API payloads, headers, tokens, images, config values, and debugging logs.

This tool helps encode plain text to Base64 and decode Base64 back into readable text.

Useful for:

API debugging
header inspection
encoded payload fragments
quick validation of Base64 strings

Hash Generator

https://www.devtoolstack.in/hash-generator/

Hashes are useful for checksums, verification, debugging, and comparing values.

The Hash Generator can create common digests such as:

MD5
SHA-1
SHA-256

Useful for quick verification, test data, and support workflows.

UUID Generator and Validator

https://www.devtoolstack.in/uuid-generator/

UUIDs are used everywhere in APIs, databases, logs, and distributed systems.

This tool helps generate and validate UUID values quickly.

Useful for:

test data
request IDs
correlation IDs
database keys
log tracing

Time, scheduling, regex, and system utilities

Timestamp Converter

https://www.devtoolstack.in/timestamp-converter/

Timestamps are often copied from logs, API responses, databases, or monitoring dashboards.

This tool converts between:

Unix timestamps
ISO dates
local time values
UTC-oriented debugging values

Useful when you need to understand what happened and when.

Cron Parser

https://www.devtoolstack.in/cron-parser/

Cron expressions are compact but not always easy to read.

The Cron Parser helps explain schedules in human-readable language.

Useful for:

job schedule review
incident debugging
deployment automation
support tickets

Regex Tester

https://www.devtoolstack.in/regex-tester/

Regex work is easier when you can test against realistic sample text.

The Regex Tester helps with:

match highlighting
flags
captured groups
sample text testing
pattern validation

Regex Explainer

https://www.devtoolstack.in/regex-explainer/

The Regex Explainer helps break a pattern into understandable parts.

This pairs well with the Regex Tester: test behavior first, then explain the structure.

Chmod Calculator

https://www.devtoolstack.in/chmod-calculator/

File permissions can be easy to misread. The Chmod Calculator helps convert permissions into readable numeric and symbolic forms.

Useful for:

Linux permission checks
deployment scripts
server setup
debugging access issues

Why this can be better than scattered single-purpose tools

I do not think every developer needs one giant tool for everything. But I do think there is value in a consistent toolbox for repeated debugging tasks.

DevToolStack is built around a few practical advantages:

Consistent UI

Once you use one tool, the others feel familiar. Input, output, copy, download, clear, and feedback patterns stay consistent.

Direct workflow links

Each page links to related tools. For example, URL Parser links naturally to URL Encoder, cURL to Fetch, and JWT Decoder.

Browser-first speed

Most workflows are instant and do not require backend setup from the user.

No login-first experience

You can open a page and use the tool immediately.

Copy and download actions

Many tools include copy/download output so the result can move into tickets, docs, tests, or code review notes.

Guide content for learning

DevToolStack also includes guide pages for important tools, so the site is not only a utility hub but also a learning/reference resource.

Guides start here:

https://www.devtoolstack.in/#guides

When I use DevToolStack personally

I use it most when I am moving through small debugging steps:

checking if a redirect rule is wrong
formatting a payload from logs
decoding a token expiry
converting a timestamp from an incident
cleaning SQL before review
parsing a URL from a callback failure
testing a regex before using it in code
converting cURL examples into browser fetch code

None of these tasks are huge by themselves. But removing friction from them makes the actual debugging work smoother.
