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 |
|---|---|---|
| Runs on | Any browser, any device. Nothing to install. | Windows, macOS, and Linux desktop app. |
| Price | Free for you and one collaborator. Academic teams pay a flat per-lab rate. | Per-seat license or subscription. The free Viewer opens files without editing. |
| Cloning | Restriction digest with a gel preview, and construct assembly that joins parts end to end. | Restriction, Gibson, In-Fusion, Golden Gate, Gateway, and TOPO cloning, simulated step by step, plus site-directed mutagenesis. |
| Plasmid maps | Circular, linear, and sequence views with translation layers, and auto-annotation from a library of common parts. | Circular, linear, and sequence views, and auto-annotation from its curated feature and enzyme database. |
| Primer design | Primer pairs for a target region, scored, with melting temperature and product size. | Primers for PCR and for each cloning method, with melting temperature and product size. |
| Sequence analysis | Pairwise and multiple alignment, Sanger chromatogram (.ab1) alignment, BLAST, ORF finder, CRISPR guide design, codon optimization, phylogenetic trees, dotplots, sequence logos, and RNA folding. | Pairwise and multiple alignment, ORF finder, and Sanger chromatogram (.ab1) alignment. |
| Import and export formats | Imports FASTA, GenBank, SnapGene .dna, and Sanger .ab1 traces. Exports FASTA, GenBank in a project export, maps as SVG or PNG, and a Sanger alignment as SVG, PDF, PNG, or TIFF. | Reads and writes .dna, GenBank, FASTA, and EMBL. Exports maps as PNG or PDF. |
| What a sequence links to | The samples, images, and notebook pages it belongs to, and the sequence it was made from. | Its own cloning history inside the .dna file. |
| Who can open it | Everyone on the project, in the browser, at the same time. | One person at a time, by passing the .dna file. |
| Beyond sequences | Image analysis, flow cytometry, samples, notebook, and figures 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
