Free developer tools (no signup)

Small, free tools for filing bugs and wiring up coding agents: a bug report template generator, a steps to reproduce generator, a bug severity and priority calculator, an MCP server config generator, a console log cleaner, and a HAR file sanitizer. Every one runs entirely in your browser, nothing you type or drop in is sent anywhere, and the output is something a developer or a coding agent can act on.

Bug triage and agent setup

The tools

Bug report template generator

Fill in what happened and get a clean, structured Markdown bug report with steps to reproduce, expected and actual results, environment, and space for the console error.

Open the tool

Steps to reproduce generator

Describe what you did and get clear, numbered repro steps with the expected and actual results, frequency, and environment, ready to paste into any tracker.

Open the tool

Bug severity and priority calculator

Answer four questions about impact, scope, workaround, and timing and get severity and priority labels on a 4x4 matrix, with the justification written for the ticket.

Open the tool

MCP server config generator

Pick your client (Claude Code, Claude Desktop, Cursor, VS Code, or Windsurf) and get correct, ready-to-paste MCP config JSON, with the file path and CLI alternative stated.

Open the tool

Console log cleaner

Paste raw console output and get a deduped, grouped, noise-stripped log as Markdown or JSON: errors with their stack traces, warnings, and everything else, with xN counts.

Open the tool

HAR file sanitizer and viewer

Drop in a HAR file and get a sanitised copy with cookies, auth headers, tokens, and bodies replaced with [REDACTED], plus a redaction receipt and a waterfall summary. Nothing is uploaded.

Open the tool

AGENTS.md generator

Answer questions about your project and get a ready-to-commit AGENTS.md. Fill in the setup command, build and test steps, conventions, and paths to leave alone. Claude Code, Codex, and Cursor all read it. No signup, runs in your browser.

These tools do by hand what Quell does automatically.

Quell is the agent-native feedback platform: the widget captures the report, the repro context, and the console with every piece of feedback, as agent-readable feedback your coding agent can act on. Bring your own AI, no token tax.
