Need plain STL files from a Bambu Studio or PrusaSlicer 3MF project? Export one STL per object or plate, or one merged file, in your browser.

It also packs STL files into a 3MF.

Turn an SVG logo or lettering into a 3D printable STL: set the height and size in millimeters, keep the holes in letters like A and O, and check it in a 3D preview.

Converted in your browser, never uploaded.

Blender writes OBJ in meters with Y up, so the STL can come out 1,000 times too small and lying on its back.

This converter scales the units to millimeters and turns Y-up to Z-up. Binary or ASCII STL, and STL to OBJ too.

No upload.

Paste a package-lock.json or yarn.lock and see what is in it: the package count, every package installed at more than one version, git and tarball sources, and which dependencies run install scripts.

The file never leaves your browser.

Found a KSUID in a log and need to know when it was created? Paste it to read its timestamp and payload, or generate 1 to 1000 time-sortable KSUIDs at once.

Runs in your browser with the Web Crypto API.

See what is inside a .torrent before you add it to a client: the files and their sizes, the trackers, the piece size and the info hash, plus a magnet link to copy.

Parsed locally in your browser. Nothing is uploaded or downloaded.

Flushing DNS clears one cache: your machine's.

We flushed dnsmasq and the next answer still came back with TTL 125, not a fresh one. 1.1.1.1 upstream had kept its own copy.

Commands for Mac, Windows and Linux, and how to purge the resolver above you:

Alpine's sshd had a password-login bypass, fixed November 5 in OpenSSH 10.6p2. It affects Linux on musl libc without PAM. Set PasswordAuthentication no, then upgrade. ssh -V won't confirm the fix; apk list -I will.

Convert a Word file to Markdown: headings, lists, tables, links, footnotes and images carry over, or export HTML and plain text. Nothing is uploaded.

[devtoollab @devtoollab]

Turn Markdown into a real Word file with headings, tables, code blocks, links and footnotes. Pick Letter or A4. It builds in your browser.

[devtoollab @devtoollab]

Turn a text-based PDF into Markdown in your browser. Headings, lists, links and simple tables survive, and the file is read locally, never uploaded. Scanned PDFs need OCR first.

Two open-source job search agents earned almost 150,000 GitHub stars in about seven months. We read both: career-ops loads about 52,800 tokens of instructions per job, ai-job-search about 12,900. Neither presses Submit.

Open STL, OBJ, PLY and 3MF files in your browser. Rotate the model, check its size, volume and print weight, then export a binary STL. Free.

Preview a DXF with its layers, blocks, arcs, splines, hatches and text, then convert it to SVG in your browser. ASCII and binary DXF up to 200 MB, never uploaded.

CVE-2026-98432 is in the Linux TCP handshake, so every listening IPv4 TCP port reaches it. Debian, RHEL, AlmaLinux and Amazon Linux have fixed kernels; Ubuntu had none on Nov 3.

How to check, patch and reboot, or filter IPv4 options until you can:

Paste an iptables-save file or a one-line rule and get nftables back. Output matches iptables-translate 1.8.11, checked on more than 25,000 rules, and 1.8.11 output that nft rejects is corrected or flagged.

Free, in your browser, nothing to install:

[devtoollab @devtoollab]

Paste hex from tcpdump -XX, Wireshark, xxd or hexdump -C and read every Ethernet, IPv4, IPv6, TCP, UDP and ICMP header field with its byte offset.

It recomputes each checksum, shows the right value when one is wrong, and decodes IP and TCP options.

A stock PostgreSQL install assumes a tiny machine: 128MB of shared_buffers and 4MB of work_mem.

Enter RAM, CPUs, storage and workload, and get tuned postgresql.conf lines or ALTER SYSTEM statements for PostgreSQL 10 to 19, each value explained.

TrueForge on the open model GLM-5.2 cost $3.00 a run in TrueFoundry's own benchmark, against $11.80 for Claude Managed Agents on Opus 4.8.

Five open-source agent harnesses compared, from license to where the agent's code runs.
