AI coding assistant or developer productivity tool
Sourcery is worth evaluating for developers and engineering teams writing, reviewing or maintaining software when the main need is code assistance or developer workflow support. The main buying risk is that AI-generated code must be reviewed, tested and checked for security before shipping, so teams should verify pricing, data handling and output quality before scaling.
Sourcery is a AI coding assistant or developer productivity tool for developers and engineering teams writing, reviewing or maintaining software. It is most useful for code assistance, developer workflow support and debugging or refactoring help.

The page now explains who should use Sourcery, the most relevant use cases, the buying risks, likely alternatives, and where to verify current product details. Pricing note: Pricing, free-plan availability, usage limits and enterprise terms can change; verify the current plan on the official website before purchase. Use this page as a buyer-fit summary rather than a replacement for vendor documentation.
Before standardizing on Sourcery, validate pricing, limits, data handling, output quality and team workflow fit.
Three capabilities that set Sourcery apart from its nearest competitors.
Which tier and workflow actually fits depends on how you work. Here's the specific recommendation by role.

Clear buyer-fit and alternative comparison.
Current tiers and what you get at each price point. Verified against the vendor's pricing page.
| Plan | Price | What you get | Best for |
|---|---|---|---|
| Current pricing note | Verify official source | Pricing, free-plan availability, usage limits and enterprise terms can change; verify the current plan on the official website before purchase. | Buyers validating workflow fit |
| Team or business route | Plan-dependent | Review collaboration, admin, security and usage limits before rollout. | Buyers validating workflow fit |
| Enterprise route | Custom or usage-based | Enterprise buying usually depends on seats, usage, data controls, support and compliance requirements. | Buyers validating workflow fit |
Scenario: A small team uses Sourcery on one repeated workflow for a month.
Sourcery: Varies ·
Manual equivalent: Manual review and execution time varies by team ·
You save: Potential savings depend on adoption and review time
Caveat: ROI depends on adoption, usage limits, plan cost, output quality and whether the workflow repeats often.
The numbers that matter — context limits, quotas, and what the tool actually supports.
What you actually get — a representative prompt and response.
Copy these into Sourcery as-is. Each targets a different high-value workflow.
You are Sourcery, an AI refactoring assistant for Python. Task: refactor a single Python function that I will paste below. Constraints: preserve public API and runtime behavior; keep the original signature and docstring; do not introduce third-party libraries; prefer comprehensions, builtins, short-circuiting, and clearer control flow; keep variable names intact unless renaming increases clarity. Output format: 1) the complete refactored function code block only, 2) a 2-3 bullet terse explanation of the key changes and why they are safer/cleaner. Example input (for style): def process(items): ... - I will paste my function now.
You are Sourcery, an automated refactoring engine. Task: analyze the Python file text I will provide and remove unused imports and unused local/module-level variables. Constraints: do not change runtime semantics (avoid removing imports used by import hooks or string-evaluated names), preserve __all__ and exported names, respect conditional imports (keep if used in platform-specific blocks). Output format: 1) a unified diff (git-style) showing removed lines, 2) a short list of removed identifiers and the reason (unused, shadowed, or false-positive risk). Example: provide full file content after this prompt.
You are Sourcery advising an engineering manager. Input: a short repo summary (number of Python files, total LOC, test coverage percent, critical microservices list). Task: produce a prioritized 5-item refactor plan tailored to that repo. Constraints: include estimated LOC affected, estimated review effort (Low/Med/High), risk level (Low/Med/High), required test or migration steps, and an expected CI metric improvement. Output format: JSON array of five objects with fields: rule_name, rationale, loc_affected_estimate, effort, risk, tests_required, expected_impact. Example input: {"py_files":120,"loc":35000,"coverage":62}.
You are Sourcery generating a CI configuration for GitHub Actions. Task: output a ready-to-paste .github/workflows/sourcery.yml file that scans Python files, posts PR comments for suggestions, and fails the job when new issues exceed a configurable threshold. Constraints: include inputs for API token (secrets.SOURCERY_TOKEN), exclude paths (tests/, vendor/), and allow a numeric threshold parameter; use a matrix for python versions 3.8-3.11. Output format: the complete YAML workflow file content followed by a 2-3 line explanation of how to adjust threshold and exclusions. Example: show the workflow content only, then the explanation.
You are a Senior Engineer designing Sourcery-driven PR comment templates and acceptance rules. Task: produce a JSON object containing three templated PR comments (style, refactor-risky, rename/behavioral) with placeholders, plus matching acceptance criteria and reviewer guidance. Constraints: include examples (few-shot) illustrating one comment filled for a simple list-comprehension suggestion and one for a risky refactor requiring a test; each template must include: title, body_template, actionable checklist, required approvals, and suggested labels. Output format: a single JSON object with keys 'style', 'risky', 'rename' each mapping to the described template object. Example: show how the 'style' template looks when filled for converting a loop to a comprehension.
You are Sourcery's rules engineer. Task: design three custom refactoring rules for repository automation. For each rule, provide: rule_id, human-readable description, AST match pattern or regex, transformation pseudocode, before/after code examples, unit-test snippet demonstrating expected change, priority (Low/Med/High), and rollback notes if behavior changes. Constraints: every rule must preserve behavior unless explicitly marked 'behavioral' and must include a short risk mitigation plan. Output format: a JSON array of three rule objects. Example: include one rule converting manual index loops to enumerate-based loops.
