## CodeThreat

CodeThreat positions itself as an all-in-one application security platform for engineering teams that find traditional static analysis too noisy. Instead of relying only on pattern rules, it layers AI agents on top of the scanning engine: one agent reviews code changes at pull-request level, another re-examines each finding and explains why it is probably a false positive, and another maps the whole repository to build context around architecture, endpoints, dependencies and data flows. Findings therefore arrive with project context rather than as an undifferentiated list of alerts.

Coverage spans the main AppSec categories in a single product — SAST for source code, SCA for dependencies, infrastructure-as-code scanning, container security and secret scanning — which reduces the number of separate tools a security team has to integrate and correlate. The AI SAST layer is aimed at issues that rule-based scanners often miss, such as logical flaws, authentication path problems and risky data flows. The vendor reports support for more than 27 programming languages and frameworks, with native integrations for GitHub, GitLab, Bitbucket, CI/CD pipelines and cloud providers.

Commercially, CodeThreat follows a land-and-expand model: a free plan for small teams, a per-contributor Pro plan for teams shipping at scale, and an Enterprise tier adding on-premises deployment, SLA-backed support, advanced compliance reporting, private LLM hosting options and manual invoicing. All-in-one consolidation plus enterprise deployment options such as private LLM hosting suggest the target buyer sits in security engineering at mid-size to large software organisations.

**Pricing & Plans:** Freemium with a published entry price: Free plan at $0/month (3 private repositories, limited agentic PR review and false-positive elimination, SAST + SCA), Pro at $39 per contributor per month adding RBAC, secret scanning, infrastructure security, Jira integration and vulnerability reporting/exports, and Enterprise pricing on request for on-prem deployment, SLA support, compliance reporting and private LLM hosting.

- **Agentic PR review:** An AI agent analyses code changes at pull-request level and surfaces risks before merge, so security becomes part of code review rather than a post-release audit.
- **False positive elimination:** A dedicated agent re-checks each finding, flags non-exploitable ones and explains why they are likely false positives, so developers spend their time on real vulnerabilities.
- **AI SAST with project context:** Understands repository context to detect complex issues such as logic flaws, authentication problems and unsafe data flows that rule-based scanners frequently miss.
- **Repository mapping and agentic repo analysis:** Maps the entire codebase, links components and flows, and generates insights on architecture, documentation, endpoints, dependencies and data flow for faster onboarding.
- **Unified AppSec coverage:** SAST, SCA, IaC scanning, container security and secret scanning in one platform, with integrations for GitHub, GitLab, Bitbucket and CI/CD pipelines across 27+ languages.

**Strengths:** AI agents filter false positives and explain findings in developer-friendly language, which reduces alert fatigue; Genuinely consolidated coverage: SAST, SCA, IaC, container and secret scanning in one platform; Transparent self-serve pricing with a free tier and a $39 per contributor Pro plan; Wide language support (27+) and native integrations with GitHub, GitLab, Bitbucket and CI/CD pipelines

**Limitations:** The most advanced governance features — on-prem deployment, SLA support, private LLM hosting — are locked behind Enterprise pricing that must be quoted; Effectiveness depends on how well the AI agents understand a given codebase, so heavily customised or unusual stacks may need evaluation; Free plan limits private repositories to three, which is tight for anything beyond a small team

## DiffDuo

DiffDuo is a lightweight diff checker that runs entirely client-side. You paste text into the Original and Changed boxes, or drag and drop plain-text files up to 50 MB each, and the tool renders the differences as you type. Removed lines are shown in red, added lines in green, and the specific words or characters that changed are highlighted with a darker background inside modified lines. You can switch between a two-column split view and a single-column unified view that follows the same format as git diff and patch files, with hunk headers such as @@ -12,7 +12,9 @@ and collapsed unchanged regions.

Practical comparison controls include ignore whitespace and ignore case toggles, a configurable context setting (3 lines, 10 lines or full file), and a copy-patch button. Long jobs such as files with 100,000+ lines are processed on a background thread so the page stays responsive. The interface is available in a wide range of languages including English, Turkish, Spanish, Portuguese, French, German, Italian, Dutch, Polish, Russian, Ukrainian, Arabic, Hindi, Indonesian, Vietnamese, Japanese, Korean and Simplified Chinese.

The tool is intentionally narrow in scope. It is not an AI code review service and does not summarise pull requests; it is a fast, private diff viewer for the moments when you want to see exactly what changed between two blocks of text. DiffDuo is free to use with no sign-up, no account, no cap on the number of comparisons and no advertising. Companion pages cover JSON comparison and list comparison, both of which also run locally in the browser.

**Pricing & Plans:** DiffDuo is completely free: no sign-up, no account, no limit on the number of comparisons and no ads. Comparison runs locally in your browser.

- **Split and unified views:** Read changes in two columns side by side, or switch to a single-column unified diff in the same format as git diff and patch files.
- **Word-level highlighting:** Darker highlights mark the exact words and characters that changed inside a modified line, not just the lines that differ.
- **Local, private processing:** The comparison runs entirely in your browser, so confidential code, contracts and config files never leave your device.
- **Whitespace and case tolerance:** Ignore whitespace, indentation and capitalisation differences, and control how much unchanged context is shown around each change.
- **Large-file handling:** Compares plain-text files up to 50 MB in a background thread, so pages with hundreds of thousands of lines do not freeze the UI.

**Strengths:** Runs fully in the browser, so sensitive text and code are never uploaded; Free with no sign-up, no usage limits and no advertising; Word-level highlighting makes edits inside a line easy to spot; Unified view matches git diff and patch format, including hunk headers

**Limitations:** Limited to plain-text comparison, with no semantic or AI-based code review; No account, saved history or team collaboration features; Requires JavaScript to be enabled in the browser; No desktop or command-line client, so it is a manual copy-and-paste workflow
