Autonomous Software Repair with 100% Verifiable Guarantees
The autonomous developer copilot and GitHub App that catches failing tests, synthesizes isolated deterministic reproduction proofs, applies minimal surgical patches, and ships verified green Pull Requests in under two seconds.
Zero Guessing
Strict mechanical verification before any pull request is opened.
Sub-2s Latency
End-to-end autonomous repair with zero cloud infrastructure overhead.
Open-Core + BYOK
Gemini 2.0 Flash, OpenAI, Claude, and local Ollama supported.
Broken Pipelines Cost Millions in Engineering Hours
Modern engineering teams spend up to 25% of every sprint cycle manually diagnosing failing test suites, flaky async timeouts, and subtle dependency deprecations.
The Legacy Status Quo
A CI pipeline breaks at 2:00 AM. Developers wait for manual triage, context-switch through 5,000-line logs, and iterate through guesses until something compiles.
The Bartholomew Solution
Catches the failure webhook, generates an isolated reproduction proof, applies the minimal surgical patch, and opens a green PR before anyone wakes up.
$18B+ Market for Developer Productivity Tooling
As software velocity surges, CI/CD reliability and automated software repair represent the highest-ROI bottleneck in modern developer toolchains.
Total Addressable Market for DevOps and automated testing by 2028.

Three Steps of Mechanical Verification
Unlike conversational LLMs that guess solutions, Bartholomew guarantees deterministic correctness through a closed-loop verification engine.
Step 1 — Isolate and Reproduce
Clones the failing commit into a fully isolated sandbox and synthesizes a standalone reproduction script that proves the defect is real.
Step 2 — Minimal AST Patch
Applies a surgical compiler-level AST patch strictly addressing the root-cause failure with zero collateral changes to surrounding code.
Step 3 — 100% Verification
Executes the full test suite locally to prove 100% green passes with zero regressions before any Pull Request is opened.
Why Bartholomew Wins: Deterministic Guarantees
| Capability | Generic AI Copilots | Bartholomew |
|---|---|---|
| Failure Reproduction | None (guesses from prompt) | Synthesizes standalone reproduction proof |
| Verification Engine | None (user verifies manually) | Automated 100% test suite execution |
| GitHub Integration | Manual copy-paste into chat | 1-Click Webhook GitHub App |
| Resolution Speed | 10 to 30 minutes manual | Under 2.0 seconds autonomous |
| Cloud Compute Cost | API tokens per iteration | $0.00 per fix (local engine) |
Empowering Teams to Focus on What Matters
For Individual Engineers
Eliminates the 2:00 AM broken pipeline. Developers spend their time building high-value features rather than debugging flaky async timeouts and deprecated AST syntax.
For Engineering Leadership
Drastically reduces CI compute waste, increases PR merge velocity, and guarantees clean test suites across large microservice architectures.
Transparent B2B SaaS Pricing
High-margin developer tool subscription model with frictionless bottom-up adoption.
Developer
Open-source CLI, Chrome and Edge extension, local AST diagnostics up to 100 fixes per month.
Pro Repository
Unlimited automated CI fixes for a single repository with deterministic reproduction tests.
Team Organization
Unlimited GitHub repos, parallel fix queues, flaky test quarantining, and team notifications.
Explore the Live Platform
All Bartholomew interfaces are live and interactive today:
Operations Workspace
Real-time daemon telemetry, connected repository status, and interactive webhook triggers.
Open OperationsAuto-Fix Simulator
Interactive 3-scenario sandbox demonstrating autonomous isolated reproduction and AST repair.
Open SimulatorDeveloper Console
Repository connection, BYOK AI settings, and autonomous PR history ledger.
Open ConsoleDeterministic Mechanical Verification
"While LLMs are great at writing boilerplate, production systems require deterministic guarantees. We built Bartholomew to replace guessing with mechanical verification: isolate the defect, compute the minimal surgical fix, prove that 100% of tests pass, and ship the green PR before anyone even wakes up."
