Cloning and plasmid design in the browser
SnapGene vs. Conspecta
A feature-by-feature comparison.
SnapGene is a polished desktop tool for cloning simulation, plasmid maps, and sequence design, loved for its clean maps and .dna files, licensed per seat with a free read-only viewer. It's part of Dotmatics, the scientific-software suite Siemens acquired in 2025. Conspecta brings cloning, primer design, alignment, and restriction analysis into the browser, connected to your samples, images, and notebook, free for you and one collaborator.
| Capability | Conspecta | SnapGene |
|---|---|---|
| Platform | Runs in any modern browser on desktop, tablet, or phone. Nothing to install. | Desktop app for Windows and macOS, licensed per seat. A free read-only viewer is available. |
| License & cost | Free for you and one collaborator. Academic teams pay a flat per-lab rate. | Paid per-seat license or subscription. The full editor has no free tier. |
| Cloning | Cloning wizard with gel visualization. | Polished cloning simulation across common methods. |
| Plasmid maps & annotation | Annotated maps and sequence editing. | Its signature strength, clean plasmid maps and automatic annotation. |
| Primer design | Primer design built in. | Primer design built in. |
| Alignment & restriction | Pairwise and multiple alignment, restriction analysis. | Alignment and restriction tools. |
| File formats | Imports and exports common sequence formats like GenBank and FASTA. | Uses its own .dna format, and reads and writes GenBank and FASTA. |
| Sample context | Constructs and sequences link to the samples and images they belong to. | Files on a workstation, not linked to samples. |
| Collaboration | Shared team workspace you open from anywhere. | Single-user. Sharing means passing .dna files around. |
| Beyond sequences | Image analysis, flow cytometry, and figures live in the same project. | Sequence and cloning tools only. |
How the workflows differ
Why labs look for a SnapGene alternative
SnapGene is a focused, polished app, and its plasmid maps are the reason many labs love it. The friction usually isn't the design work, it's everything around it. There's a per-seat license, a desktop app to install on each machine, and constructs that live as .dna files on one workstation and get emailed around. For a lab that wants a collaborator to open a map without buying a seat, that setup gets in the way.
Cloning and sequence design in the browser
Conspecta brings the everyday sequence work online. You plan and simulate a cloning strategy with gel visualization, design primers, annotate a map, and run alignment and restriction analysis, all in the browser with nothing to install. The student on a Chromebook and the collaborator across campus open the same link and see the same construct.
Constructs connected to the rest of your work
The clearest difference is what a construct connects to. SnapGene keeps the sequence in a file and leaves the sample it came from and the imaging that validated it to other tools. In Conspecta, a construct links to the samples and images it belongs to, so the cloning, the microscopy, and the flow run for one experiment sit in the same project. SnapGene is the cloning piece of the Dotmatics suite, sitting apart from its separately licensed notebook (LabArchives), figures (Prism), and flow (OMIQ) tools.
In practice that means less bookkeeping across tools. You aren't matching a .dna file to a tube in a freezer and a stain in an imaging folder, so there's less chance of a mislabeled construct or a figure built from a stale export.
What switching actually looks like
Moving over is mostly a one-time step. You import your sequences in common formats like GenBank and FASTA and keep working, no install required. Your sequences export back out in those same formats, so nothing is locked in. SnapGene's free viewer stays available if you ever need to open a .dna file, so keeping both around during a transition is easy.
SnapGene vs. Conspecta: the bottom line
Switch to Conspecta if
- You want cloning, primer design, and sequence tools in the browser with nothing to install
- You want sequence design free for you and one collaborator, without a per-seat license
- You want constructs linked to the samples and images they belong to
- You also work with images or flow and want them in the same project
- Your team should share one workspace instead of passing .dna files around
Stay on SnapGene if
- SnapGene's polished plasmid maps and annotation are central to how you work
- You need a fully offline desktop tool that works without a network connection
- Your lab is standardized on the .dna format and SnapGene's cloning simulation
- You want a single dedicated app just for cloning and sequence design
