Features

An API client, database client and AI toolkit for VS Code

Everything you'd normally open four apps for — an API client, a SQL GUI, a token calculator and a secret scanner — in the VS Code sidebar.

REST API client

Build, send and inspect requests in one panel

A Postman-style workflow inside VS Code, with no account and nothing synced to a server. Paste a URL or a cURL command and press Enter.

Every HTTP method, plus GraphQL (query, variables, operation name) and WebSocket
Bearer, Basic, API key and OAuth 2.0 auth
Environments with {{variable}} substitution, collections in folders and request history
Import and export cURL; generate fetch, Axios, Python, Go, Java and C# code
Ready-made request shapes for OpenAI, Anthropic, Gemini, Azure OpenAI and Ollama
Assertions, request chaining, performance runs, response diff and mock servers

Database client

Ten databases, one form, zero extra installs

Fill in a short form or paste a connection string. DevSnip Pro detects the engine and shows its schemas, tables, collections or keys.

Paginated data grid with sort, search, filters and resizable columns
Type-aware row editor, Extended JSON for MongoDB and an editor for every Redis type
Query editor with highlighting, Format, inline errors and Ctrl/Cmd+Enter to run the selection
Cancel long-running queries on the server; copy results as JSON or CSV
Passwords in your OS keychain, destructive statements confirmed, read-only connections enforced
Every driver ships with the extension — Oracle runs in Thin mode, no Oracle Client needed

AI & LLM tools

Know what a prompt costs before you send it

Token counts and cost estimates run locally — no API key needed.

Tokens and per-request, daily and monthly cost across 18 chat models
Prompt Builder that fills templates and checks them for common mistakes
Output Cleaner that pulls JSON out of a model reply, repairs and validates it
RAG helpers: chunking tester, context budget, vector store setup, retrieval evaluation
JSON → TOON to shrink prompts, LLM Client Setup and AI App Starter

Security Hub

Catch hard-coded secrets before they ship

Four scans in one panel. Every finding shows its evidence, severity and fix, and results export as Markdown or JSON.

Workspace audit: API keys, tokens and passwords (masked), injection risks and weak crypto
Cloud & containers: Terraform, Kubernetes, Docker Compose, Dockerfiles and GitHub Actions
Dependencies & config: lockfiles, unbounded ranges, compromised packages and .env hygiene
Endpoint scan: TLS, HSTS, CSP, CORS, cookies, auth behaviour and rate limiting

CSV & Excel viewer

Open spreadsheets as a fast, editable grid

View and edit .csv, .tsv and .xlsx files without leaving the editor — nothing leaves your machine and no macro runs.

Every sheet of a workbook, with dates, currencies and number formats shown the way Excel does
Search, sort and filter hundreds of thousands of rows; separator and encoding auto-detected
Column stats and Excel-style sum and average for a selection
Edit cells, rows and columns with undo; untouched cells, styles, charts and macros are kept
Export what you see as CSV, JSON or a Markdown table

Debug & cleanup

Debug logs that know your language and your logger

Language-aware logging and cleanup for JavaScript, TypeScript, Python, Java, Kotlin, C#, Dart and Swift.

Insert Debug Log (Ctrl+Alt+Shift+L) labels the variable with its file and line
Uses the logger the file already has — SLF4J, ILogger, logging, Log.d, debugPrint, os.Logger
Clean Debug Logs removes leftovers across the workspace, ignoring comments and strings
Run & Debug Configurations writes launch.json for Next.js, Vite, FastAPI, Spring Boot, .NET, Flutter and more
Remove Unused Imports and Unused Dependencies for npm, Python and Flutter/Dart

Snippets & debug logs

Type ds- and get code that compiles

56 framework snippets, each expanded by VS Code and then compiled — and run where the framework allows it. Then log any variable with its file and line in one keystroke.

Type ds-rest and press Tab for a Spring REST controller, then select id and press Ctrl+Alt+Shift+L to log it through SLF4J.

Language	Snippets
Java / Spring Boot	REST controller, service, JPA entity & repository, ProblemDetail advice, MockMvc and JUnit 5 tests, SLF4J logger
C# / ASP.NET Core	Minimal API group, API controller, IExceptionHandler, EF Core DbContext, [LoggerMessage], xUnit tests
Python	FastAPI app & router, Pydantic model, Flask route, Django view, logging setup, pytest fixtures
TypeScript / React / Next.js	Components, hooks, context, route handlers, server actions, Express router, zod, Vitest
Dart / Flutter	Stateless and stateful widgets, FutureBuilder, JSON model, widget and unit tests
Swift / SwiftUI	SwiftUI view, ObservableObject view model, async JSON request, os.Logger

Save your own: select code, run “Create Snippet” and it shows up in IntelliSense in 39 languages.
API Resource Scaffolder generates a validated CRUD API for Express, NestJS, Next.js, Fastify, Spring Boot, ASP.NET Core or FastAPI.
When you're done, Clean Debug Logs removes the leftovers across the workspace, ignoring comments and strings.
