Overleaf is the reason most people reading this write LaTeX in a browser at all. It took a toolchain that needed a local install, a package manager, and a tolerance for cryptic errors, and made it something you could just open. Any honest comparison starts there.
We built TeXposit because we wanted different things from an editor, not because the existing one was bad. What follows is an attempt to lay out the real differences without the usual competitor page dishonesty. There is a section on where Overleaf wins, and it is not decorative.
The short version
| TeXposit | Overleaf | |
|---|---|---|
| Where it compiles | In your browser as you type, plus full server compilation for final PDFs | On the server |
| Collaborators (free tier) | Unlimited | Limited |
| Version history | Full history free, git backed | Paid plans |
| Local file editing | Edit directly on your own disk | Sync integrations on paid plans |
| Authorship provenance | Cryptographically signed record | Not available |
| Hosting | EU, self hostable via Docker | Global, Server Pro for institutions |
| Publisher templates | General templates | Extensive, with direct submission |
| Maturity | Public beta | Over a decade in production |
How the architectures differ
The compilation model is the big one. Overleaf compiles on its servers, so your project crosses the network every time you want to see it. TeXposit does that too for final output, but adds Live Preview, a LaTeX engine compiled to WebAssembly that runs in your browser and recompiles as you type. The difference shows up in the drafting loop rather than in the finished PDF. We wrote about why that loop matters separately.
Then there is where your files actually live. Overleaf is the system of record and you sync out of it. TeXposit projects are git repositories where every save is a commit attributed to whoever made it, and local file sync lets you edit a project directly on your own disk with the editor's features still applied. "On my machine" and "in the editor" stop being two worlds you periodically reconcile.
Hosting matters more than it used to. TeXposit runs on European infrastructure and is GDPR compliant, which for some institutions is a procurement requirement rather than a preference. It is also self hostable with a single Docker command. Overleaf offers a Server Pro edition for institutions; the difference is that ours is the same deployment we run ourselves rather than a separate enterprise product.
Where we deliberately went further
Every project carries a signed record of who wrote what and how much was AI assisted, exportable as a tamper evident report. As journals and funders start asking authors to disclose AI involvement, "I attest that..." is becoming a weaker answer than "here is the signed record." Nothing equivalent exists in Overleaf, because Overleaf was designed before anyone was asking. There is more on this in the provenance post.
The AI assistant is built so its work can be checked. It searches real academic databases and inserts real BibTeX instead of generating citations from memory, which matters because fabricated references are now turning up in published literature. You can also point it at a local model through Ollama, so an unpublished paper never leaves your machine.
The hybrid .tex.md format lets you write Markdown where Markdown is enough and drop into LaTeX where you need it, compiling to the same output. Most papers are ninety percent prose and ten percent things that genuinely need LaTeX. The hybrid format stops you paying syntax overhead on the ninety.
On limits: TeXposit is in free public beta with unlimited projects, unlimited collaborators, full version history, and no compile timeouts. Overleaf's free tier caps collaborators per project and compile time. We would rather you checked their current plans yourself than trusted a competitor's summary of them, because pricing changes and a page like this one is the last place you should learn it.
Where Overleaf is the better choice
This is the section most comparison pages leave out.
Overleaf has run a production LaTeX service for more than a decade, and its toolchain handles a long tail of unusual packages, classes, and edge cases that any newer service, ours included, will sometimes miss. It also has direct relationships with a large number of publishers, so if your target journal has an official Overleaf template and a submission link, that is a real workflow advantage we cannot match today.
Incumbency counts for something too. If your university has a site licence, your collaborators already have accounts, and your lab's projects already live there, that inertia is worth real money in saved friction. Switching cost is a legitimate reason to stay.
And we are in beta. Overleaf is not. For a thesis due in six weeks, boring and proven is a feature. We would rather you finished your thesis than switched tools halfway through it.
Five questions that actually decide it
- Does your institution require EU hosting or self hosting? If so, that probably settles it on its own.
- Do you need to document AI involvement in your writing? If your field or funder is moving that way, provenance stops being a nice extra.
- Are you working around Overleaf's collaborator or compile limits? Working around a limit is a cost you have already agreed to pay.
- Do you depend on an unusual package or a specific publisher template? Test it before you commit. This is the most common reason a switch fails.
- How close is your deadline? Do not migrate a project that is nearly finished. Start with the next one.
Importing an Overleaf project takes about thirty seconds and the import guide walks through it. Nothing stops you keeping both, and plenty of people draft in one and submit from the other. If you try it and it does not fit, we would genuinely like to know why.
