flyto-core > **A debuggable automation engine. Trace every step. Replay from any point.** > > **flyto2.com** · Desktop App · Documentation · YouTube Try in 30 seconds Screenshots captured. Performance metrics extracted. JSON report saved. **Every step traced.** --- What happens when step 8 fails? With a shell script you re-run the whole thing. With flyto-core: Steps 1–7 are instant. Only step 8 re-executes. Full context preserved. --- 3 recipes to try now Every recipe is traced. Every run is replayable. See all 32 recipes → --- Install --- The 85-line problem Here's what competitive pricing analysis looks like in Python: **Python** — 85 lines **flyto-core** — 12 steps No trace. No replay. No timing. If step 5 fails, re-run everything. Full trace. Replay from any step. Per-step timing. Every run is debuggable. --- What's New in v2.19.0 • **Smart validate_params** — auto-corrects wrong field names via alias mapping (e.g., to ) and suggests alternatives when a non-existent module is requested • **Enhanced search_modules** — word-level and tag matching scoring replaces the old substring-only search, producing more relevant results for natural language queries • **browser.extract default text mode** — when no are specified, now returns the text content of matched elements by default (previously returned empty objects) • **Browser channel support** — pass to to use the system-installed Chrome instead of bundled Chromium, useful for bypassing anti-bot detection on sites that fingerprint headless browsers Engine Features • **Execution Trace** — structured record of every step: input, output, timing, status • **Replay** — re-execute from any step with the original (or modified) context • **Breakpoints** — pause execution at any step, inspect state, resume • **Evidence Snapshots** — full state before and after each step boundary • **Data Lineage** — track data flow across steps, build dependency graphs • **Timeout Guard** — configurable workflow-level and per-step timeout protection --- 412 Modules, 78 Categories | Category | Count | Examples | |----------|-------|----------| | | 38 | launch, goto, click, extract, screenshot, fill forms, wait | | | 24 | switch, loop, branch, parallel, retry, circuit breaker, rate limit | | | 15 | filter, sort, map, reduce, unique, chunk, flatten | | | 11 | reverse, uppercase, split, replace, trim, slugify, template | | | 11 | OpenAI, Anthropic, Gemini, Notion, Slack, Telegram | | | 10 | keys, values, merge, pick, omit, get, set, flatten | | | 9 | resize, convert, crop, rotate, watermark, OCR, compress | | | 8 | json/xml/yaml/csv parse and generate | | | 8 | read, write, copy, move, delete, exists, edit, diff | | | 8 | mean, median, percentile, correlation, standard deviation | | | 7 | email, url, json, phone, credit card | | | 6 | run, ps, logs, stop, build, inspect | | | 6 | zip create/extract, tar create/extract, gzip, gunzip | | | 6 | calculate, round, ceil, floor, power, abs | | | 5 | get_pods, apply, logs, scale, describe | | | 4 | AES encrypt/decrypt, JWT create/verify | | | 4 | ping, traceroute, whois, port scan | | | 4 | parse, extract text, merge, compress | | | 4 | upload, download, list, delete | | | 4 | Gmail send/search, Calendar create/list events | | | 4 | get, set, delete, clear (memory + Redis) | | | 3 | remote exec, SFTP upload, SFTP download | | | 3 | clone, commit, diff | | | 3 | execute Python, Shell, JavaScript | | | 1 | DNS lookup (A, AAAA, MX, CNAME, TXT, NS) | | | 1 | HTTP health check with SSL cert verification | See the **Full Module Catalog** for every module, parameter, and description. --- How is this different? | | Playwright / Selenium | Shell scripts | flyto-core | |-|----------------------|---------------|------------| | Step 8 fails | Re-run everything | Re-run everything | | | What happened at step 3? | Add print(), re-run | Add echo, re-run | Full trace: input, output, timing | | Browser + API + file I/O | Write glue code | 3 languages | All built-in | | Share with team | "Clone my repo" | "Clone my repo" | | | Run in CI | Wrap in pytest/bash | Fragile | | --- How to Use CLI — run workflows from the terminal MCP Server — for Claude Code, Cursor, Windsurf Or add to your MCP config: Your AI gets all modules as tools.

Run for full options. See **docs/RECIPES.md** for full documentation. --- Write Your Own Workflows Recipes are just YAML files. Write your own: Every run produces an execution trace and state snapshots. If step 3 fails, replay from step 3 — no re-running the whole thing. --- For Module Authors See **Module Specification** for the complete guide. --- Contributing We welcome contributions!
