Text & Regex Studio
Live regular expression debugger with capture tree visualization, high-speed case transforms, visual diff inspection, and typographic telemetry — computed strictly in client memory.
Zero-Knowledge Architecture & Execution Benchmarks
How ToolAcre guarantees data privacy and immune-level browser thread resilience.
Client PCRE & ES2024
Compiled into WebAssembly using LLVM/Emscripten, our PCRE2 engine brings C-speed regex processing directly into browser RAM with absolute feature parity.
ReDoS Guard Dog
Pathological backtracking algorithms are intercepted inside dedicated isolated Web Workers. If matching steps exceed 1,000,000, execution self-terminates gracefully.
Ephemeral Volatile RAM
Buffers are preserved strictly in active DOM variables. There are zero cookies, zero LocalStorage dumps, zero IndexedDB persistence, and zero telemetry analytics.
Polyglot Code Export
Generate native, boilerplate-ready regex logic snippets for JavaScript, Python, Golang (regexp), Rust (regex crate), and PHP with matching escape sequences.
Frequently Asked Questions
безпека Is it safe to paste proprietary source code, API keys, or confidential server logs?
expand_lessYes, absolutely. ToolAcre enforces a strict static-edge design. Open your browser's Developer Tools (F12) > Network tab: you will observe exactly zero outbound HTTP/XHR/WebSocket payloads while executing, replacing, or testing regular expressions. All execution occurs in client heap space.
psychology How does ToolAcre prevent catastrophic backtracking (ReDoS) from crashing my browser?
expand_more
Every regular expression match operation is executed in an off-thread Web Worker. Before compiling, the AST checks for nested quantifiers like (a+)+$. If step execution exceeds 250ms or 1,000,000 backtracks, the worker terminates instantly, returning an error banner without freezing your tab.
tune Which regular expression engine flavors are supported?
expand_more
ToolAcre natively provides ECMAScript 2024 (V8/SpiderMonkey), PCRE2 via WebAssembly compiled C libraries, and Python 3.12 standard re flavor emulation. You can switch between flavors in Section 01 with zero reload penalty.
find_replace Can I perform multi-line regex replacements with numbered capture groups?
expand_more
Yes. The replacement engine supports indexed backreferences ($1, $2), entire match references ($&), and named capture groups ($<name>) with instant side-by-side visual diffing.
