TOPTRONIC® · Long Project Configurator · Windows 10 and 11 · works offline
One folder for a long project, and the record of what was decided. Fully offline.
TLPC is a Windows desktop app for work that runs across many sessions: a software project, a legal matter, a course, a small business. It keeps the brief, the rules, the templates and the prompts you used in one folder you can copy, back up or hand over. No account. Runs from a USB stick.
- 🔒 Nothing leaves this machine unless a button says it will
- 📦 No account, no cloud, no telemetry
- 🧯 No MCP server can run inside it
Windows 10 & 11 · Runs from a USB stick · Plain JSON, yours to keep
Project: Solar Controller Firmware ● loaded
Templates: 12 reusable setups
Resources: Model + IDE profiles
Status: ● Offline mode — no network calls
Built on a proven foundation
TLPC inherits the same Rust + egui desktop stack TPEE has shipped through 180+ builds. It is in active development, and the build named on this page is a working program, not a mock-up.
- ✅ Proven stack — the foundation TPEE has hardened over 180+ builds
- ✅ In development, not abandoned — active builds shipping now
- ✅ Reuses what you know — shares TPEE's model and IDE profile data
What it is
Set a project up once, then start every session from the same folder.
TLPC takes everything a project needs — its defining .tlpc.json file, reusable templates, model and IDE profiles, learning material and your own rules — and keeps it together in one local workspace you can open, edit and carry. Your projects become portable files you own outright, not records trapped in someone's cloud. Everything a project reaches for is catalogued beside it — agent skills, MCP servers and repositories, every row opened and measured before it was listed.
One file per project, in your hands
Every project is a single, human-readable .tlpc.json file. Open it in any editor, back it up, hand it to a teammate. No proprietary database to migrate out of later.
Start every new project from a known-good baseline
Save a proven setup as a template and re-import it into a new project, so every job starts from configuration you already know works.
The profiles you rely on, always available
Keep the model profiles, IDE profiles and reference tables you depend on as local, offline data. Always present, never fetched, never behind a login.
A new teammate can read the project instead of asking you
A lesson browser walks a new member through configuring and maintaining a long project, in the same order the window draws it.
Your workspace follows you
General settings and themes persist to a local preferences file. Set it up once, then carry the same setup across sessions and machines on a USB stick.
Keep your team's configuration consistent
Open the project rules folder and edit your rules from inside the app, so every project your team configures stays consistent no matter who runs the file.
The catalogue
3,530 projects, opened and measured before they were written down.
Every row in this catalogue was checked before it was listed: the address answers, the description says what the project does, and the category says where it belongs. It is the same list the TLPC desktop app carries in its Install windows, published here so you can read it before you buy anything - and so you can name the exact skill, server or repository a long project should rely on.
Agent skills — 859 MCP servers — 833 Repositories — 1,838
TLPC never connects to any of them. Not one of these is fetched, installed or started by TLPC - the catalogue is a list you read and a plan you copy, and your own tools do the rest.
Security & privacy
Strictly offline, by design.
TLPC follows the same firm policy as its sister product: it makes no network call except the two you start yourself — Check for Updates and Send Feedback — and connects to no other service. Your projects never leave your machine, because there is nothing in the program is built to send them.
Two buttons, and nothing else
No HTTP clients, no async runtimes, no telemetry. Nothing leaves your machine unless you press Check for Updates or Send Feedback.
Local files only
All persistence is local JSON — tlpc_preferences.json and your project files. You can read every byte yourself.
No MCP servers
External MCP tooling is never connected; it appears only as documentation. There is nothing in the program that can reach a server.
Sister to TPEE
TPEE writes the prompts. TLPC configures the projects.
TPEE, the Toptronic® Prompt Engineering Editor, shapes every prompt into the 12 proven sections LLMs need. TLPC is its sibling: it configures and manages the projects those prompts are used in. Together they cover the whole lifecycle, from designing a prompt to organizing the projects that use it, all offline.
- Same proven stack as TPEE (Rust + egui), hardened over 180+ builds.
- Reuses TPEE's model and IDE profile data by copy-and-adapt; never modifies it.
- One workflow: write in TPEE, configure and run in TLPC.
TPEE + TLPC
TPEE — the prompt editor: 12 sections, scored 0–100, exported to 20+ IDEs.
TLPC — the project configurator: projects, templates, resources, rules.

Who it's for
If you run more than one long project, this is for you.
Prompt engineers juggling many setups
Stop re-creating the same configuration in every session. Keep each project's full setup in one file you can reopen instantly.
Developers who want plain, portable files
Projects as versionable JSON files you own — not data trapped in a service you have to log into.
Teams that need everyone on the same setup
Consistent project configuration without another SaaS login or admin console to manage.
A legal matter, a case or a claim
The correspondence, the filings and the reasoning kept in one folder, so the file you hand over is the file you worked from.
A course you teach
Lesson plans, hand-outs and the notes on what worked last term, reopened next term without rebuilding them.
A small business or a trade
Quotes, suppliers and the jobs in flight — no subscription, no account, a folder on the office PC and one on the laptop.
One folder per project. Everywhere you take it. Nothing to sign in to, nothing that leaves the machine.
Before you write
Five questions people ask first.
Is TLPC free?
It is a paid licence: one payment, and the build you buy keeps working. Nothing is offered for download yet because the build is not code-signed; when it is, the price and the buy button will be on this page.
Does it send anything to a server?
The program itself makes no outbound call except two you start yourself: Check for Updates and Send Feedback. Your projects, prompts, rules and preferences stay in folders you choose on your own disk. No account, no MCP server, no telemetry.
How is it different from TPEE?
TPEE writes and scores one prompt at a time. TLPC organises the long project that prompt lives in: the folders, the master rules, the sessions, the PRDs and the record of what was decided. They are sister products and they sit side by side on the same desktop.
What does a project actually look like on disk?
One folder per project, named after the prefix you choose, holding sub-folders for the history of chats and actions, the session starts, the prompts, the PRD documents, the settings and the LLM rules — each one named after that same prefix, so a folder found on a backup disk says which project it is.
Does TLPC come with a warranty?
Every licence is a lifetime licence: one payment, every build we release installs over yours at no extra cost, and if TLPC is retired the last build stays downloadable. Write to [email protected] with your order reference if something does not work as the manual describes.
A four-slide tour
What TLPC does, once you are inside it.
Four slides, no video and no sign-up. Swipe, scroll, or use the numbered buttons under the deck — the slides are ordinary HTML.
The deck scrolls sideways; the buttons jump straight to a slide.
The Toptronic LifeTime Warranty
Buy it once. Keep it for life.
Every TLPC licence is a lifetime licence. There is no subscription, no renewal date and no per-seat meter — the build you buy keeps working for as long as you keep the file.
- One payment, no renewal — your licence does not expire and nothing switches off after a year.
- Updates for the life of the product — every build we release for TLPC installs over the one you own, at no extra cost.
- Yours even if we stop — if TLPC is ever retired, the last build we shipped stays downloadable and keeps working on your computer.
What is covered
Every feature of the copy you bought, on a machine that runs Windows 10 or 11: where it does not work as this site and the user manual describe it, we make it work to your satisfaction for the life of the product — and every release we ship for TLPC installs over your copy at no extra cost while the product is maintained.
What is not covered
- A copy we cannot show was bought from us.
- A machine that cannot run Windows 10 or 11, or a fault caused by software outside TLPC.
How to claim
Write to [email protected] with your order reference and one sentence describing what goes wrong. A person reads it, and the fix costs you nothing.
The warranty covers the software you bought. It is not a promise of new features, and it does not cover a machine that cannot run Windows 10 or 11.
New in Build 091
Six new categories, 270 more checked repositories, and a list that leaves the app as a script you can run.
The catalogue holds 3,530 items in 111 categories now: 859 agent skills, 833 MCP servers and 1,838 repositories, and 270 of them are new. Six of those categories did not exist before this build - Multi-Agent Orchestration, WebGPU & In-Browser Inference, Prompt Compression & Context Caching, Desktop Automation & RPA, Reproducible Builds & Provenance, and Code Graphs & Repo Indexing - and each one starts with at least nine rows, because a category that narrows to two rows is a category nobody presses twice. The Install pane has a fifth thing to copy beside the plan, the JSON manifest, the CSV and the two saved files: a shell script with one git clone line per row of the filtered list, in the order you are looking at, with rows already marked installed left as comments. TLPC writes that script and runs nothing.
Your next long project starts as one folder, on your own disk.
TLPC runs on Windows 10 and 11. It is not code-signed yet, so there is no installer and nothing for sale on this page. Leave your address and you will get one email the day a signed build is ready to buy — no list sharing, no partner offers, no second email.
[email protected] · Windows 10 & 11
Two emails, no marketing
Tell us where to write when TLPC is ready to buy.
TLPC is built and running, but it is not code-signed yet, and nothing unsigned is ever sold or offered for download here. Leave your address and you will get two emails and no more: one now, to confirm the address is yours, and one the day a signed installer exists and the price is printed.
Feedback
Tell me what broke, or what you want next
This form reaches the same table the app's own Help > Send Feedback reaches, and both are read by a person. A defect is written down with the build number before it is fixed, so say what you were doing and what you expected.
Thank you
Made possible by the engineers who wrote to us.
TLPC is new, so this wall is the family's rather than TLPC's own yet: the marks below belong to engineers who sent feedback on the Toptronic® Prompt Engineering Editor and on Toptronic® Assistant, the two products TLPC is built beside. Write to [email protected] or use the feedback form below, and TLPC's own wall starts with you.
