Start with your team’s writing workflow, not the logo on the login page. Overleaf is still the default choice for many research groups, and the service says it supports more than 16 million users worldwide [source: Overleaf]. But it is not the only serious option. If your project needs tighter Git control, notebook support, journal formatting, or simpler coauthor review, several Overleaf alternatives deserve a close look.
TLDR: Overleaf is best for most pure LaTeX teams, but it is not always the best fit for labs with code, data, and mixed writing styles. For example, a six-person research group with two Python users, two LaTeX-heavy authors, and two reviewers may save hours by using CoCalc or GitHub Codespaces instead of passing files around. Papeeria and TeXPage are closer to classic online LaTeX editors, while Authorea, SciSpace, and Fidus Writer suit teams that care more about publishing workflow than raw TeX control.
What to compare before switching
Do not pick an editor just because it has real-time editing. That is the easy part now. Compare these factors first:
- Compilation reliability: Can it handle large bibliographies, custom classes, and many figures?
- Version control: Does it support Git, file history, or both?
- Collaboration style: Are comments, tracked changes, and permissions clear?
- Data and code support: Can the platform sit near notebooks, scripts, or computational work?
- Export options: Can you get clean PDF, LaTeX source, Word, JATS, or journal-ready files?
1. Papeeria
Papeeria is one of the closest Overleaf-style alternatives. It offers online LaTeX editing, live collaboration, templates, and PDF preview. The interface feels more focused than flashy, which is fine for serious writing.
It works best for students, thesis writers, and small academic teams that want a familiar LaTeX setup without extra publishing tools. The weakness is scale. Very complex projects can feel slower, and the template library is not as broad as Overleaf’s. Still, for standard papers and reports, it is a clean option.
2. CoCalc
CoCalc is the strongest choice here for teams that mix LaTeX with code. It supports LaTeX documents, Jupyter notebooks, terminals, course management, and shared project spaces. That matters when the paper is tied to computations, plots, or reproducible analysis.
The catch is that CoCalc feels more technical. A non-coding coauthor may need help for the first hour. Once set up, though, it gives a research group one place for writing and computation. That can reduce messy “final figure v7” email chains.
3. Authorea
Authorea is built for research writing rather than only LaTeX editing. It supports collaborative authoring, references, figures, and scientific publishing workflows. It can be useful when authors want a more structured writing space and do not want every contributor touching raw TeX.
This makes it attractive for interdisciplinary teams. A biologist, statistician, and clinical researcher can work together without forcing everyone into the same LaTeX habits. The tradeoff is control. If you need deep TeX customization, you may feel boxed in sooner than expected.
4. SciSpace
SciSpace, formerly known to many users through typesetting and journal formatting tools, is useful when the end goal is submission-ready output. It focuses on manuscript preparation, formatting, references, and research workflows.
It is not the best pick for authors who want to write every macro by hand. But it can help teams that spend too much time fixing citation style, margins, and journal rules. Honestly, it feels like formatting should not eat an entire afternoon, yet it often does. SciSpace tries to cut that pain.
5. Fidus Writer
Fidus Writer is a serious option for academic writing with citations, structured documents, and collaborative editing. It is not a pure LaTeX clone. Think of it as a scholarly writing platform that can support technical publishing needs without asking every author to learn TeX syntax.
It fits humanities, social science, and mixed research teams well. Reviewers can focus on the argument, not broken commands. The downside is clear: heavy mathematical writing will still feel better in a true LaTeX editor.
6. GitHub Codespaces with LaTeX Workshop
GitHub Codespaces paired with VS Code and LaTeX extensions is a strong choice for power users. It gives you Git, branches, pull requests, issue tracking, and a real development setup in the browser. GitHub describes Codespaces as cloud development environments that run from a repository [source: GitHub].
This setup is excellent for technical papers, software documentation, and reproducible research. It is also the least friendly option for casual coauthors. Expect to waste time on setup if your group has never used Git. Once the workflow is stable, though, review becomes much cleaner than random edits in a shared file.
7. TeXPage
TeXPage is another browser-based LaTeX editor worth testing if you want a simpler writing space. It offers online compilation and collaboration features aimed at LaTeX users. It is less famous than Overleaf, but that does not make it unserious.
TeXPage may suit users who want a more direct editor experience and do not need a large ecosystem around the tool. Before moving a major paper, test your class files, bibliography style, and image-heavy sections. A 20-page draft can behave very differently from a 180-page thesis.
Best picks by use case
- Closest Overleaf alternative: Papeeria.
- Best for code and data: CoCalc.
- Best for Git-based teams: GitHub Codespaces with VS Code.
- Best for journal workflow: SciSpace.
- Best for non-technical coauthors: Authorea or Fidus Writer.
- Best lightweight LaTeX test: TeXPage.
How to test before you commit
Run a real trial with one existing paper. Do not use a blank demo file. Upload your bibliography, figures, custom commands, and journal class. Invite two coauthors and ask them to leave comments, resolve edits, and export the final PDF.
Time the boring tasks. How long does compile take? How many clicks does it take to restore an older version? Can a reviewer understand the comment system in five minutes? These small checks reveal more than any feature table.
The safest choice is still the one your team will actually use. Overleaf remains hard to beat for standard LaTeX collaboration. But if your work includes code, strict version control, complex publishing needs, or coauthors who hate TeX, the seven tools above are worth a serious comparison.
