FixFleet

AI Bug Fixer for GitHub · GitLab · Jira · Linear · Bitbucket · Azure DevOps — or any Excel / Word / PDF bug list

Reads bugs from your tracker or straight from a bug file (no tracker or token needed), parses stack traces and screenshots, pre-narrows the search to the right files, and dispatches to your AI of choice. Chat "fix all" — real bugs get fixed, suggestions get implemented, only solid fixes are kept (anything uncertain is undone), and items that aren't actually bugs are reported, not "fixed". All local. No commits. Bring your own AI.

⚡ Quick start (60 seconds)

Fastest path — a bug file, no tracker, no token

  1. Install the VSCode extension (1 click above)
  2. Click 🚀 FixFleet icon💬 Start with a bug file — no token needed
  3. 📎 Load your Excel / Word / PDF bug list — any column layout works, screenshots included
  4. Say fix all — real bugs get fixed, suggestions get implemented, anything uncertain is undone, and non-bugs are reported back to you
  5. Review the diff, commit yourself — FixFleet never commits or pushes

With your issue tracker

  1. Get an access token for your tracker — full guides below
  2. Configure → Bug Source: Issue Tracker → pick provider → paste token + project URL → save
  3. Click any bug in the sidebar → ✨ Fix This Bug with AI — or select several and batch-fix
  4. Review the diff, commit yourself

🔑 Connect Your Tracker (Token Setup Guides)

FixFleet supports 6 issue trackers. Pick yours below — each guide covers exactly where to click, which permissions to grant, and what to paste into FixFleet.

🔒 Security note: tokens are stored in your VSCode user settings on your machine only. FixFleet has no servers — your token goes directly from your laptop to your tracker's API and nowhere else.

🟧 GitLab — gitlab.com or self-hosted

1. Generate the token

  1. Open https://gitlab.com/-/user_settings/personal_access_tokens (or https://YOUR-GITLAB-HOST/-/user_settings/personal_access_tokens for self-hosted)
  2. Click "Add new token"
  3. Fill in:
    • Token name: fixfleet
    • Expiration date: up to 1 year ahead
  4. Select scopes — tick ONE of:
    • read_api — read-only (list + read bugs). Enough for fixing.
    • api — read + write. Needed later for auto-commenting / closing issues.
  5. Click "Create personal access token"
  6. Copy the token immediately — GitLab shows it only once. Format: glpat-xxxxxxxxxxxxxxxxxxxx

2. What to paste in FixFleet

Field Value
Provider GitLab
Token glpat-xxxxxxxxxxxxxxxxxxxx
Project URL https://gitlab.com/group/project — any GitLab URL works (with .git, /-/issues, SSH form, or short group/project)

Requirements

  • Bugs must carry the label Bug (capital B) to show up
  • Your account needs at least Reporter role on the project
⬛ GitHub — github.com or GitHub Enterprise

1. Generate the token (classic PAT)

  1. Open https://github.com/settings/tokens
  2. Click "Generate new token""Generate new token (classic)"
  3. Fill in:
    • Note: fixfleet
    • Expiration: 90 days or custom
  4. Select scopes — tick ONE of:
    • repo — full repository access (covers private repos)
    • public_repo — public repos only (lighter permission)
  5. Click "Generate token"
  6. Copy immediately — shown once. Format: ghp_xxxxxxxxxxxxxxxxxxxx

Alternative: fine-grained PATs also work — grant "Issues: Read" on the target repository.

2. What to paste in FixFleet

Field Value
Provider GitHub
Token ghp_xxxxxxxxxxxxxxxxxxxx
Project URL https://github.com/owner/repo — also accepts .git, /issues, SSH, or short owner/repo

Requirements

  • Bugs must carry the label bug (lowercase — GitHub's default label)
  • Pull requests are automatically filtered out
🟦 Jira — Atlassian Cloud (*.atlassian.net)

1. Generate the API token

  1. Open https://id.atlassian.com/manage-profile/security/api-tokens
  2. Click "Create API token"
  3. Label: fixfleet → click Create

🧠 How it works

┌─ Bug source: tracker issue (GitHub / GitLab / Jira / Linear / Bitbucket / Azure DevOps)
│            OR a bug file (Excel / Word / PDF — screenshots included, no token needed)
│
├─ Parse: description, steps, expected/actual, stack traces, logs, embedded screenshots
│
├─ QA check: does this item belong to THIS project? (wrong-project items are
│            reported to you, never "fixed")
│
├─ Locate: extract file paths, symbols, stack frames → rank candidates → inline top file
│
├─ Dispatch to AI agent (Claude / Codex / Gemini / Cursor / Aider / Qwen / any free API)
│   The AI decides: defect → fix it · suggestion → implement it ·
│   code already correct → change nothing, tell you why
│
├─ Keep or undo: only solid fixes are kept — anything uncertain is reverted
│                automatically and marked "needs review"
│
└─ Done — local-only changes + a bug ledger (fixed / needs review / not a bug /
          not this project), ready for your review

Chat-driven: the 💬 chat panel runs this whole flow conversationally — load bugs.xlsx, fix all, status.

Token-aware: per-issue, session, and daily budgets prevent paid-plan overruns.

Multi-backend: detected CLI agents shown as installed; pick one per session.

Nothing fixed twice: a persistent ledger tracks every bug across sources, catches duplicates, and remembers what's done.

🎯 Why FixFleet

vs. doing it manually

Triages 50 bugs in the time it takes you to read 5 — and tells you which ones aren't even bugs.

vs. AI inside the issue (e.g. GitLab Duo, GitHub Copilot Workspace)

  • Costs nothing extra — uses AI plans you already pay for
  • Works without a tracker at all — your QA team's Excel sheet is enough
  • Edits actual files locally, not just comments
  • You pick the AI — not locked to one vendor
  • One tool for all trackers — GitHub + GitLab + Jira + Linear + Bitbucket + Azure DevOps
  • Works on private/self-hosted instances without exposing source to a SaaS

vs. running Claude/Codex CLI manually

  • Structured prompts — extracts steps, logs, and screenshots automatically
  • Pre-narrows file scope — saves 60–80% tokens
  • Keeps only solid fixes — anything uncertain is undone automatically, so a bulk run can't wreck your tree
  • QA gate built in — wrong-project items and not-actually-bugs get reported, not "fixed"
  • Bug ledger — batch 50 bugs without fixing anything twice
  • Budget caps — never blows through paid quotas

❓ FAQ

Does this use any paid backend / hidden costs?

No. FixFleet runs 100% locally on your machine. No FixFleet servers, no Azure, no cloud component. You pay for nothing beyond AI plans you already own. The VSCode extension is free. The PyPI package is free. Updates forever, free.

Does FixFleet collect any data?

Only anonymous usage analytics (via Google Analytics): event names and coarse metadata like provider key, backend name, and success/failure — never your code, tokens, project URLs, or issue content. Used purely to find bugs and see which trackers/backends need attention.

Opt out anytime:

  • CLI: fixfleet --config-set telemetry.enabled=false (or set DO_NOT_TRACK=1)
  • VSCode: uncheck fixfleet.telemetry in settings (the global VS Code telemetry setting is respected too)
What's the difference between the VSCode extension and the CLI?

Same engine, two interfaces:

  • CLI (pip install fixfleet) — interactive terminal flow (GitLab), plus flags for everything: --file bugs.xlsx --auto-fix fixes a bug file in one command; --list-bugs-json --provider github ... for the other trackers.
  • VSCode extension — premium UI sidebar, 💬 chat, and click-to-fix workflow for all 6 trackers and bug files; calls the CLI under the hood

Install both if you want flexibility. Extension auto-installs the CLI on first run if missing.

Will it ever commit or push my changes?

Never. FixFleet edits files locally and leaves your working tree dirty. You review the diff (git diff), then commit + push manually. This is intentional — AI fixes need human review before shipping.

Can I use it without any issue tracker?

Yes — that's the fastest path. Switch Bug Source to Local bug files (Chat), load an Excel (.xlsx), Word (.docx), or PDF bug list (any column layout — headers are mapped automatically, embedded screenshots are extracted for the AI to look at), and say fix all. No tracker account, no token. PDF needs one optional extra: pip install "fixfleet[files]".

What happens to items that aren't real bugs?

FixFleet doesn't blindly "fix" everything on the list:

  • Suggestions / feature requests (however they're phrased) get implemented
  • Reports where the code is actually correct — the AI inspects the code first and tells you "checked the code — no defect found" instead of changing things
  • Items that don't belong to your project (wrong files/components) are flagged with a warning and skipped
  • Uncertain fixes are undone automatically and marked "needs review" — a bulk run can never wreck your working tree
Which issue trackers are supported?

All six, fully implemented:

Tracker Bug filter Notes
GitLab label Bug gitlab.com + self-hosted
GitHub label bug github.com + Enterprise, PRs auto-filtered
Jira Issue Type = Bug Atlassian Cloud
Linear label Bug per-team
Bitbucket kind = bug Cloud only
Azure DevOps Work Item Type = Bug Boards

Paste any URL — FixFleet auto-detects the provider. See Token setup guides.

Does it work with self-hosted GitLab / GitHub Enterprise?

Yes. Paste your full URL (e.g. https://gitlab.mycompany.com/group/project) and FixFleet auto-detects the host. No config needed.

Which AI should I use?
  • Best quality → Claude Code (Claude Pro)
  • Fastest → Groq (free Llama 3.3 70B)
  • Biggest free quota → Google Gemini API
  • Fully offline → Ollama with qwen2.5-coder:7b
How is FixFleet different from Cursor / Cody / Copilot?

Those are autocomplete + chat tools. FixFleet is a bug-triage automator — reads your bug tracker, dispatches each ticket to an AI, scores the fix. They complement each other.

Is my code sent to FixFleet servers?

There are no FixFleet servers. Your code goes from your machine → directly to whichever AI provider you pick (Anthropic / OpenAI / Google / Groq / Ollama / etc.) using your own credentials. FixFleet is open-source — read the code and verify.


🛡️ Privacy & Security

  • 🛡️ Issue content fenced in prompts to prevent prompt-injection from malicious issue authors
  • 📂 Config + state stored in ~/.bugfixer.json / ~/.bugfixer-state.json (your home dir, never in any repo)
  • 🚫 Never commits, never pushes, never collects telemetry
